Eric Bennett grabbed the shop door chain and hoisted the roll up door for the first time, in 2000. He started his mechanical career as a certified diesel mechanic with 60-weight always flowing through his blood stream. Finally, he gave into his entrepreneurial spirit and his desire to make motorcycles his life—he opened his own shop on Signal Hill. The rest is motorcycle history, much of it spent at the Bonneville Salt Flats with his dad, Bob.

He recently owned a modified twin cam FLH, but a customer made him a deal he couldn’t refuse, so he let it go. Then a deal on a Dyna surfaced and he made a quick move to snatch it. This time, he decided he would take it to the concrete and rebuild every aspect of the bike to be moderately fast, ultimately reliable, precise, and built with absolutely all the best mechanical intentions and components in mind. You get to see the 106-inch project unfold before your very eyes right here.

One of the benefits of running a service center in the largest city in Los Angeles County includes encountering every possible mechanical malady and the ability to research whatever solution might be necessary. Since LA is also the motorcycle media hub, he has constant opportunities to test anything new on the market. After working on Twin Cams since their introduction into the market in 1998, Eric has watched every configuration, modification, performance recipe, and model roll in and out of his shop.

With this build he could pour every lesson and improvement into his own ride. It started as a bone stock 2004, 88 cubic inch TwinCam. Eric could choose from any hot rod configuration in the world, but he chose to roll with a 106-inch kit from S&S and Branch re-tuned heads. He started the process by installing a JIMS Timken conversion into his left case and welding his crankpin into the S&S lower end after it was balanced.

“With superior S&S flywheels, I didn’t need to monkey with the cases,” Eric said.

 He bored the stock barrels from 3 ¾ to 3 7/8 inches and increased his stroke from 4 inches to 4.5. With JIMS tools he pressed in the JIMS race (using green Loctite) (9-59-1) while keeping his fixture perfectly flat and the hole in the race at 12 o’clock.

Using a JIMS fixture tool, he was able to drill guide holes in the case for Timken bearing and race oiling. The JIMS tool holds the drill and guides it. The drills are set to indicate the depth. Otherwise, he would need to use transfer punches and a milling machine. Then he used another JIMS tool to drill for the race fastener holes, and used tap guides to prevent misalignment.

“I’ve made tap guides for every size tap,” Eric said.

One of the benefits of the higher quality Timken lower end bearings is their ability to lock the lower-end into place.

“I have never seen a Timken bearing fail,” Eric said. Until recently Timken’s were used since 1957. “I’ve seen dozens of roller bearing failures!”

The cost saving shift to roller bearings started in 2003 during the 100th anniversary season. “The best Twin Cams were built in 2002,” Eric confirmed. “Better engines, still carbureted and with 1-inch axles for strength and stability.”

Eric used red Loctite on the race screws. He uses a tool for installing both Timken races at the same time. Kelly McKernnan, an amazing machinist out of Portland, Oregon, manufactured it.

The next phase included welding the S&S flywheels. Anytime Eric has a twin cam lower end out of a customer’s bike, he welds the crankpin in place with stainless TIG rod. It doesn’t create much heat and is not a structural weld; it just cements alignment and prevents shifting. He always checks the true after welding.

Next, he installed the Timken bearing by heating the race to expand it, and it slippped over the shaft easily. There is very little endplay in the shaft, just .001-.002-inch. Eric cinched down the top bearing with another JIMS tool, then pressed in the main seal and spacer with yet another JIMS tool.

At this point, we shifted to pressing the new S&S cam bearings into the new heavy-duty Screamin’ Eagle cam plate for hydraulic cam tensioners, but Eric chose to shift to an S&S gear drive system, so he blocked off the oil passages to the hydraulics.

He installed Torrington cam bearings in the right case prior to installing the new cams. His plan called for installing a D&D Bob Cat exhaust system, which is 20 pounds lighter than a stock exhaust. D&D pipes come bolted together with all spring clips, flanges, and heat shields in place. “They take like two minutes to install,” Eric said.

“It’s the easiest system I have ever installed,” Eric said. “It comes with the all the components needed and the heat shields in place. No shimming is necessary or egg shaping holes.”

Day 2

We took a break for the day and grabbed a beer. But the next day, Eric installed a heavy duty Harley-Davidson pinion shaft bearing kit using a JIMS pinion bearing tool and it was time to slip the cases together with Yamabond on the case edge, while applying assembly lube on the pinion shaft. The case bolts were torqued to 18-22 ft. lb.

“Don’t forget the new oil pump O-ring when installing the high flow H-D pump,” Eric pointed out. Eric has an engine-building quirk. He continually turns the engine over, while rolling through the build process, and constantly tests for changes. “I want to catch anything that might bind early on,” Eric said. We actually ran into a small glitch while installing the cam plate.

But first, he installed the oil pump return gears, and then the separation washer and the spring, before the feed gear. He bolted the cam plate in place with ¼ -20 fasteners torqued to 120-inch- pounds. He used guide pins to help align the oil pump, and turned the engine over while tightening the pump so it would seat itself properly. He tightened two oil pump bolts, then removed the guide pins, and then tightened the other two Allens.

While aligning the cam drive gear dots, he installed the cams and used red Loctite on the drive gear Allen bolts, but used assembly lube on the washer for more accurate torque values and to prevent the bolt from galling against the washer surface for a false torque reading.

As we wrapped up the operation for the day, Eric installed the lifter with the oil holes facing the cam cover, then the guide pins, caskets and covers. No more lifter stools.

Day 3

Eric sub-leased a portion of his Signal Hill building to Branch O’Keefe, perhaps the best head porting business in California. I don’t want to put down any performance heads, but Jerry Branch, who is now about 82, built a helluva business around head performance.

Here’s a description of their heads from the Branch-O’Keefe site:

This is where is all began. Branch-O’Keefe is known throughout the industry for legendary cylinder head modification service. Our extensive reworking of stock Harley-Davidson cylinder heads begins with removal of the stock valve seats and guides. Next, the combustion chambers are heliarc welded to add additional aluminum alloy in the combustion chamber and around the valve seats for re-machining.

The valve seat pockets are then machined for larger nickel-chrome valve seats, and the combustion chamber is cut from the stock low compression rectangular shape to the legendary Branch “bathtub” chamber. After cutting the combustion chamber, new oversize valve seats and performance-quality valve guides are installed to tighter than stock tolerances.

The heads then advance to the porting room where the ports are fully hand-ported, blended and polished to Branch’s exacting specifications as proven on the dyno and flow bench. The head’s gasket surface is machined an additional 0.050-inch, which raises compression slightly. Finishing up, new oversize intake and exhaust valves (hard chrome stainless steel with stellite tips, polished face) are installed in bigger seats with a machined race-quality valve job and then hand-lapped. New seals and a high quality high-lift radius spring kit complete the installation.

The Branch O’Keefe head components are damn impressive from the titanium upper collars to the single oval wire spring with more travel and a larger diameter spring material. They have developed heads for JIMS big inch motors that produce 132 horsepower and ft-lb of torque, at an absolutely stock reliability level, even on a B motor. So natch, Eric had John O’Keefe and his master right-hand man, Paul go through his heads. Actually they used a formula they call the Dave Thew head. It’s a nickname for a performance formula. Dave beat everyone with these Branch O’Keefe head configuration. I will outline the different formulas next week.  

We started the day installing S&S pistons with wrist pins first, since the oil rings pass over the wrist pin holes. Seems odd, but it’s the nature of the short-skirted piston. “Actually it allows for more skirt on stroker motors and does away with stroker plates,” Eric said. “This piston configuration will keep a stroker running longer.” The oil ring must be positioned with the dimple in the wrist pin area in a particular location to prevent rotation. The S&S pistons use four-piece oil rings with a removable ring land.

Eric installed the bottom compression ring so that the opening faced the exhaust port area. “No gaskets are used on the bottom of the cylinders,” Eric said, “just O-rings.” He compressed the rings carefully, lubed the inside of the freshly bored cylinder and slid the cylinder into place. Then Eric spun the motor over to check for binding. “I can’t wait to hear the D&D pipe.”

Eric started to install the heads using Cometic gaskets. The heads were torqued to Cometic specs and then he set to installing the rocker boxes and the fasteners, which were torqued to 22 foot-pounds. He started from the inside and worked out. Then he slipped in the S&S Quickee-Install intake pushrods for maximum valve opening. “I run premium S&S lifters with travel limiters,” Eric said.  “They become solids at high RPMs.”

He tightened each pushrod until the valve slipped off the seat, and then let it bleed down, for about 10 minutes. He backed off the adjustment until he could spin each pushrod (one at a time). Then he backed off just one complete turn or six flats.

These shots were taken before John O’Keefe came up with a crazy notion to machine Twin Cam cylinder fins in a round configuration. Eric was knocked out by the procedure and pulled his barrels for the process.

In the next episode, Eric will slip the beautiful 106-inch Twin Cam into the stock frame, and we will discuss JIMS tools, while replacing the inner primary bearings, the slightly modified Dyna D&D pipe, and then and the new Rivera Primo clutch, the S&S G carb, and a new S&S high flow air cleaners.

Here’s the link to Mudflap Girl Part 11: http://www.bikernet.com/pages/Mudflap_Girl_FXRs_part_11_The_First_Road_Test.aspx

My son’s Mudflap Girl FXR is running and partially broken in. I even, finally, dialed in the Wire Plus Speedometer, and it’s working. I wish I knew what I was doing wrong, but that puppy works like a champ. I enjoy the tightness of the display and ease of installation. In that small cylindrical Wire Plus display, I get a speedo, a tach, trip gauge, neutral light, turn signal indicators, oil idiot light, and what else?

Okay, so it’s time to turn the Pro Street version of the Mudflap over to my son, Frank, but first we couldn’t leave the bone stock remanufactured 80-inch Evo engine alone. I reached out to S&S for a cam recommendation, and they recently built a relationship with Crane Cams.

Bruce recommended the following stock engine formula: S&S Super E carb, Crane Hi-4 ignition, S&S Cam and S&S easy-adjust pushrods, a Crane dual-fire coil, and the S&S 33-4250 breather and shim kit, for just enough pump to let this motor breathe.

I hauled the Mudflap beast on my Kendon tilt-up combo trailer to Bennett’s Performance, a very clean shop, next to Branch O’Keefe Flowmetrics, on Signal Hill. Eric Bennett, the boss, bought the Bikernet Hearse, immediately fired his girlfriend and started to cruise the backstreets of Long Beach. He traded his bagger for a Sons of Anarchy Dyna, and is about to turn the 88-inch twin cam into a 106-inch S&S night flier. His band, the Signal Hill Billies, transformed their usual light country western twang into dark blues. What the hell did I do? We will bring you reports on his engine transformation. I could swear the all-black lowered hearse smirks at me whenever I roll into his parking lot, but we won’t go there.

I pulled up the other day to find Frank’s Mudflap Girl on a lift center stage. No sooner did I enter the shop when Eric slipped out the back. A mysterious tech sauntered out of the engine room with long gray hair. “Don’t take my picture,” he said, “and don’t mention my name in the article.”

I’ve known him a long time. He’s an experienced Bonneville racer and a multiple-tour Vietnam vet, about my age. He’s only been married once, and is still married to the same woman. “I swear,” he said, “I’ve never pulled my military issue bayonet on my wife.”

I’ve been married five times and Eric three, and he just broke up with his long-time girlfriend. Maybe the graybeard tech with his twisted grin was trying to say something.

What the hell could I say? I set the box of parts on the lift and started to blow the dust off the fresh engine. Eric gave me a new cone gasket, seal, and a Torrington cam bearing, in case the fresh engine was fitted with a poor quality INA bearing—it was. I removed the pipes. The tech removed the plugs, and we jacked up the bike. He popped the pushrod covers and broke out the bolt cutters to remove the stock pushrods without removing the rocker boxes.

“I roll the engine over so the valves are closed when I cut the pushrods,” Graybeard said, “so the valves don’t slam shut when the pushrods snap.”

Then he removed the point cover, and the crane Hi-4 ignition plate. “There needs to be a washer under the fastener holding the Crane point breaker plate,” he barked.

Unfortunately, I had installed the Crane system and breaker plate—my bad. I thought about my fifth wife. He pulled the cone cover with a rare Trock tool, since the master is no longer with us.

With a couple of JIMS magnetic, or H-D lifter tools the lifters were held out of the way while he pulled the stock cam and checked the bearing.

Sure enough, it was an INA cam bearing with about half the rollers of the high quality Torrington cam bearings.

JIMS tools makes a handy cam bearing puller, which was installed, and swiftly, perfectly yanked the stock bearing free. Eric made specific machined aluminum drivers for installing new bearings, which were carefully tapped into place. After it was installed, he reached in to make sure the bearing spun free, with no binding.

Next, he aligned the timing marks on the pinion gear and set up the new S&S breather gear.

Steel breather gears have better dimensional stability than plastic gears. Embedded particles can damage the crankcase breather gear cavity. A screen provides better protection than a slotted gear, so small particles are prevented from entering the gear cavity, where they may damage the gears and oil pump.

The S&S steel gear with welded in screen with larger diameter holes provides improved air flow/oil scavenging from the flywheel cavity. Crankcase flywheel cavity vacuum and oil scavenging are further improved by optimized breather window timing. Breather oil trap scavenging is significantly improved by increased scavenge port duration. These improvements are the result of exhaustive research using digital sampling and data acquisition equipment.

This gear was the standard size for late 1977—‘99 Harley-Davidson big twins. Breather gear kits include breather gear and steel endplay shim kit.

With the new S&S breather gear installed, he started to adjust the endplay with a .120 shim. “That’s usually the one,” he said. As it turned out, we went with .110-inch shim after he checked the fitment with a straight edge. Then he performed a similar operation with the cam to check endplay. We discovered that a .055-inch thick shim was needed in addition to the existing flat shim. He dug around and found one, and we were set to test it with another JIMS special tool.

The S&S 510V bolt-in cam works well with stock or ported heads. The improved ramp design results in low valve train noise. It’s meant for engines up to 96 inches and with compression as high as 10:1. It’s designed to pull its best results in the mid to upper rpm range, 3000 to 5000 rpm.

It was time to set the cam timing with the pinion bearing and breather gear slots. Then the mystery tech cleaned some of the case threads with a tap. “Too much Loctite,” he said. He touched all the stock ¼-20 Allens with blue Loctite and installed the cone and torqued them to 110 inch-pounds. He installed the appropriate washer in my breaker plate, and then the timing plate.

Before he removed the Crane Hi-4 ignition plate, he scribed the plate and the case so the timing would be right where I placed it when everything was put back together—that is, if I didn’t fuck it up in the beginning.

I peeled the S&S quick-adjust pushrods out of their vacuum-packed container and shortened them for ease of placement. These S&S jobs were a breeze. He checked for all the needed pushrod gaskets, and we compared the pushrod lengths to use the short ones on intake valves and the long ones for the exhaust.

“I adjust them the old school way,” he said. “I make sure one intake lifter is at the top of its cycle, and then adjust the other. Then visa-versa.” He waited 20 minutes between adjusting valves for the stock lifters to bleed down, but while he waited, we started to install the pipes. “No time to lose.” He made sure each pushrod would spin after it bled down. In each case, he took the slack out of the pushrod and then turned it out four turns or 24.5 flats. Once he tightened the pushrod lock nuts, he would take the half flat out of the adjustment.

Here’s the Quickee Pushrod Supplement from S&S: To install S&S quickee pushrods, thread the jam nut off the threads towards the ball end and screw the adjuster into the pushrod tube until the threads disengage and the pushrod can be collapsed

S&S Quickee Pushrods for S&S Shovelhead and all big twin engines contain two long and two short pushrods. All Sportster model and Harley-Davidson twin Cam 88 pushrodes are the same length.

We replaced the pushrod cover clips with another JIMS tool, and I finished installing the Spitfire brake master cylinder and pedal. Once together, we turned on the gas, hit the starter and it fired right to life. Our very experienced Vietnam vet tech let her warm up, adjusted the carb and quietly returned to the engine room to work on a twin cam engine build for a customer. It’s time for my son to pick up his bike and head for a paint shop or the hills.

Spitfire

1964 was an interesting year for Harley. it was the last year of the 6-volt electrical system, and last year for the kick-start only. In 1965 they stepped up to 12-volt system and the first electric start and massive batteries started to appear. So let’s get started, I removed the primary, to my surprise it had a belt drive in it.

Someone wanted a step-up from the original chain drive, unfortunately it’s covered in oil that leaked from the main shaft seal and chain oiler that was never shut off. I might be able to save it with a healthy cleaning, we’ll talk about that later. After removing the primary drive and clutch, I thought the transmission would be a good place to start the restoration.

I did the research and found out all the parts I needed to rebuild the stock 4-speed transmission were available from J&P Cycle, and manufactured by JIMS. So off to the catalog I went. I ordered all the gaskets and seals I needed to rebuild it, except one, the main drive shaft seal (which was the worst one out of the bunch). According to the manual and other people I talked to, you need to invest $250 in the special tool from JIMS. It removes and installs that seal. However, I found an old friend (older than I) sorry Danny! LOL, who knew how to R&R the seal without the so called special tool, no big deal, according to him!

Be careful not to lose the gear shaft key for the sprocket. Also, there’s a small keeper key (looks like a flat L). It holds the sprocket far enough away from the seal, so it doesn’t ride on the seal. Keep it just in case. I later found out the new seal came with the keeper, but it’s better safe than sorry, if ya know what I mean.

There are some measurements you can take with feeler gauges for the shifter forks and spacers, refer to the manual.
Also you can check the timing shifter notches for alignment after the cover has been removed, also in the manual.

I actually ended up with two manuals, the original 1964 Harley service manual and a Clymer manual. Out of the two, I prefer the original service manual, it’s so easy to read and understand an idiot can follow it. Wait a minute! It’s also a good notion to pick up a parts manual for a variety of parts illustrations not found in service manuals.

For the serious rebuild the Wolfgang Panhead Restoration book, by Rick Schunk is an excellent guide. We were fortunate to have a low mileage transmission, and only a clean- up was required.

All the schematics are hand drawn in detail, very cool and definitely vintage. For the main shaft sprocket seal, I used the old school method my friend suggested, a slide hammer. Simply drill a couple of 5/32 holes in the seal, not too deep, about ¼-inch, screw in a sheet metal screw, and slam away!

It came out on the second slam of the hammer, YEAH! Installing the new one was just as simple, add a little Vaseline or WD40 to the outside of the seal and gently and evenly tap it in. I used a brass seal installer I had lying around, moving it back and forth on the seal so it doesn’t bind. Tap it down flush with the case, and your done. The JIMS tool insures that the seal is installed perfectly square into the case.

The rebuild kit came with all the gaskets and seals. There’s an O-ring seal in the kick-start shaft that rides between two brass bushings, be sure and replace it.

You can reach in with a dental pick or small screwdriver, and remove it without pounding out the bushings. The kit comes with new gasket for speedometer cable and neutral light indicator.

I polished up all the chrome it had and added a brass kick-start pedal, it looks great! Yeah, I know, not OEM pedal, but it looks cool and is pretty close to the era. I also ordered all new chrome case screws, the old ones were rusted, plus the chrome looks better anyway. I painted the inner timing cover and polished the out cap. You will find that almost all the transmission and engine cases are cadmium platted.

Lots of guys polish or chrome them, my customer wanted them to look as factory as possible. Here it is, the finished product. Not sure what I’ll tackle next, if you have any requests, let me know, I’ll be glad to accommodate. I’ll probably go right into the engine. That’s all for now, Tail Gunner out till next time.

Mudflap Girl, chapter 10: http://www.bikernet.com/pages/Mudflap_Girl_FXRs_Part_10_Suspension_Tuning_and_Le_Pera_Seat.aspx

I can’t make it to Sturgis this year. We are focused Bonneville builds, like mad starving dogs, and the two events are only separated by two weeks. Ray is tuning and I still don’t have an engine, but we’ll cover that later. The engine could be running today, in Richmond, Virginia, at Departure Bike Works.

Okay, so what’s a poor bastard to do, when he planned to make the run to the Badlands with his brother Hamsters? They ride out from the West Coast every year. Some of the members, including Arlen Ness are in their 70s and riding custom Victory bikes. Some rode from Spearfish, South Dakota, out to Mammoth Lakes, California, to ride back to the Badlands with their brothers. So, what’s the least I could do? Meet them at their first stop in Mammoth, just east of Yosemite? 

The good doctor has owned several motorcycles, including a 1934 VL I helped get running, but one motorcycle stuck with him, a 1989 FLH. He had clocked over 200,000 miles when he decided to rebuild it. Bennett’s Performance handled the semi-stock Harley engine (the rebuild was covered on Bikernet). With a couple of thousand miles on his rebuild, and 50 on mine, (another 80-inch semi-stock Harley engine, assembled by S&S, with headwork by Branch O’Keefe), we rolled out of Los Angeles.

About 15 million folks know rolling out of Los Angeles is the biggest challenge to any weekend excursion to someplace less congested. It’s amazing, like no-man’s land at the front of any war zone. Just try to slip out of Los Angeles on a Friday. Try to peel by noon or before. If you don’t you could be faced with serious bumper-to-bumper malady, or a lane-splitting conundrum. We recently published a report about splitting lanes and the benefits. They actually made a case for increased safety in areas supporting lane-splitting.

I’ll make one case for the freedom to split lanes, maybe two. Well actually, the published study pointed out the benefits of keeping motorcycles moving during high-congestion back-ups. My point included any rider’s sense of alertness. When splitting lanes the rider’s acute awareness is on high alert. Even while putting past a myriad of parked cars, a brother never knows what could blink, so his senses are hot wired. He or she is aware of anything that moves, from a slight wheel shift, to a nod, or a turned head.

So, I split lanes as soon as I hit the 405 freeway, off the 110, the oldest freeway in the US. It runs directly into the heart of Los Angeles, downtown, from my digs in the Port of Los Angeles. As I pulled out of Wilmington, two concerns stirred my humble sense of motorcycling comfort. First, I discovered my rear chain smacking the Spitfire hand made oil tank. There was always a bothersome noise bugging me, and I finally discovered the treacherous origin, the rear left corner of the FXR-styled, rubber-mounted oil bag.

Fortunately, the Spitfire team had welded a threaded bung into the corner, and a tab off the frame. I ran across the problem during assembly and removed the tab for more clearance, but evidently not enough. So the night before the run, I removed the chain, cleaned the threads with a tap, and made a countersunk Teflon bumper to protect the tank, but would it last? Or would the chain disintegrate my protective barrier, cut a hole in my oil tank in the middle of the Mojave Desert, dump all my oil onto the highway, seize up the engine, and leave me to be tarantula bait, after I baked under the 107-degree blistering desert sun?

I also made one final adjustment to my Wire Plus speedometer sensor stuffed into the JIMS Screamin’ Eagle over-drive 6-speed transmission. I had tried everything. I was at a strange juncture. It’s been so long not working, if it worked I would have been shocked. As I pulled away from the headquarters, I wasn’t disappointed. It still didn’t work. Now, I have another idea. I didn’t connect the wire from the sensor to the speedo wire directly, but to a connection board. Maybe a direct connection would be the trick.

Somewhere in the sizzling desert, with the afternoon sun baking my feeble skull, the notion of this road test article was spawned. The Mudflap Girl FXR contained only 50 break-in miles so far; this 700-mile jaunt would be the iron test. I had followed the Eddie Trotter break-in regime, almost to the tee. With each longer and longer ride, I returned to the headquarters to make corrections, repairs, and adjustments. It was time for the acid test, a long road into one of the hottest regions in Central California, a total round trip of perhaps 700 miles in 2.5 days. That’s a big deal for this old guy.

There I was, splitting lanes across the LA airport toward Santa Monica and the good doctor’s office, where he was leaning over his knockout secretary and adjusting a tall tattooed redhead. Tough job. Sticking around his office near the coast, with a bottle of something, would’ve made my weekend.

Oh, one more concern disturbed my peace of mind. I started to write peach. I was still with the girls in the office. I hand-made the two mounts holding the single RockShox to the girder. My mind whirled with 80mph impact, a bottoming out shock, and the stress on the mounts. Would they last or toss me into the fast lane of a crowded Los Angeles freeway? Ah, for the days when we would build a bike, smoke a joint, down a shot of whiskey and ride some half-wired together chopper across town at breakneck speeds to her house. Hell, we felt so good, it didn’t matter if we made it our not.

While parked at the good doctor’s office, I inspected my Teflon pad. It was sliced severely, in just 40 miles, but the next 40 or 100 would finalize the experiment. My shock mounts hung tough, but what about the next 100 miles? We gassed up and peeled out onto a crammed 10 Santa Monica freeway. Splitting lanes and dodging merging traffic we weaved onto the 405 Freeway. It peels over the notorious Sepulveda Pass, into the San Fernando Valley, and beyond toward the 5 Golden State, high-speed direct link from Los Angeles to the bay area and San Francisco.

We just needed to cut across the 101, to the 5 for a five-mile stretch, and then off on the 14 toward the Mojave mile airport landing strip and land speed trials location. I felt every bump and groove in the crappy road as I leaned into the fast lane and poured the coals to this 80-inch beast. It ran sweet. I set up the dual-fire, Compu-Fire ignition according to instructions, and installed the Trock modified CV carb, but never adjusted any aspect of it, except the idle.

The week before we peeled out I rode to Bennett’s Performance and Eric popped the cap off the air fuel adjustment behind the float bowl, and adjusted it—it was too lean. Trock removed the cap, so the adjustment screw was operational. I rode the bike, noticed an intermittent cough, and called Eric. He recommended backing out the needle one-quarter turn. She seemed happy, and in Mojave we refueled and checked our mileage against Christian’s trip meter. We had covered 90 miles and I reloaded with 1.82 gallons for 49.45 mpg. It pulled well in any gear, even in sixth gear. The JIMS Screamin’ Eagle Overdrive transmission shifted like butter and never missed finding neutral. I geared it slightly high for a 6-speed with a 23-tooth trans sprocket and 51 on the rear wheel. 

So far, we flew along big wide freeways through the Soledad Pass, Palmdale, Lancaster, and then into Rosamond. At over 90 degrees, the freeway started to die and turn into a two-laner along-side the Pacific Crest National Trail leading into the Sequoia National Forest. It looked sorta bleak and hot to me, as I pondered the welds that held my chopped Spitfire bars together. So far, the riding position was a dream. My legs were stretched out nicely. I could move around on the very comfortable gel-impregnated Saddlemen seat with the spine relaxing channel, and just a touch of lumbar support. The bike handled well, as I adjusted to the long bike vibe.

Another rambling rural 50 miles in the desert with only rolling hills in the distance, and the 14 Highway disappeared to be replaced with the well-kept Highway 395 in Indian Wells Valley. We passed more deserted truck stops, than active ones. They were extreme sun-dried out buildings. Chipped paint was sandblasted by desert winds, and busted windows gave the dilapidated structures, gradually turning to dust a war zone appearance. I set the bike up to be a chopper for the long road, with rubber H-D pegs, old styled thick rubber Knucklehead grips, and Custom Cycle Engineering rubber-mounted traditional dogbone risers. Since the drive train was rubber-mounted, it all worked to minimize vibration.  

We followed one billboard to an old gas station turned into jerky sales headquarters. It bragged “Good jerky.” It was actually so-so, and small packages were priced at nine clams. I wanted to support their sticker-scattered cause. The smiling Hispanic broad behind the counter gave me the okay to plant a Bikernet sticker on the building, yet I couldn’t cough up nine bucks, plus tax for a bag of so-so jerky. We peeled out.

Just a handful of small towns peppered the highway with reduced speed signs, some as slow as 25 mph, perhaps a fund-raising effort. We rolled into Lone Pine and the Dow Hotel, which was packed with tourists and bikers heading to Sturgis. The Dow, built in 1923, was specifically constructed to house movie crews, since a large number of westerns were shot in the region. What a roll of the dice, but it paid off. We topped off and compared notes this time. We had sliced through 111 miles and I took 2.3 gallons, for 48.3 mpg. The doctor grabbed more fuel between stops, so he crossed 38 miles and took 1.2 gallons for 31.6 mpg. He was disappointed, and we discussed options for the future.

The good doctor noticed some drops of oil on the pavement next to my bike. My oil cap isn’t correct for the screw-in bag bung, so I found a press-in rubber cap, with a small dipstick. It worked, but loosely, and a small amount of oil seeped onto the roof of the Spirfire steel oil bag, then some trickled down the right side, onto the frame and dripped onto the pavement. I pressed the oil cap deeper into place and check the oil level, and then it dawned on me. I noticed a softening in my rear GMA brake action. That was the cause.

[page break]

I checked the Teflon pad, and it didn’t indicate any more chain damage, plus the tank was well clear of the carved edge. It appeared very secure, and my shock mount held fast. Vibration was minimal, and at every stop, folks confronted me about the Mudflap girl bike, the traditional chopper appearance, and almost every onlooker said, “Is it a rigid?”

The next morning, we faced just 99 miles for our meeting with the evil Hamsters at the Westin lodge in the heart of Mammoth lakes. The roads were perfect and our 80-inch Evos purred as the elevation increased from sea level to 4000 feet, and we were expecting another 4000 thousand and more pine trees as we cut a dusty trail toward the Sierra Nevada Mountain Range, just east of Yosemite. We stopped in picturesque Bishop for breakfast, but the two hot spots were jammed. We strolled into Whiskey Junction without a problem, then rode the remaining 40 miles to the Mammoth cut-off. I was expecting winding, twisting mountain roads into the mountain/sky resort community, but it was virtually a straight shot. My memory reminded me of a similar stop the year I hit a deer inWyoming.

We didn’t pop for the high-dollar rooms, but stayed down the street at the Sierra Motel, where the doctor pointed out a concern with his front wheel. We rode up the street to hang with the Hamsters as they rolled in as early as noon. Some rode in from Spearfish, but the Bay Area contingent, including Arlen Ness chose to fight traffic in slow lanes through Yosemite National Park. They weren’t scheduled to arrive until the early evening, so we returned to our digs to take a look at his front wheel. Under the backdoor hotel overhang, we found a massive cinder block, jacked up his FLH and removed the front axle. One of the bearings demonstrated serious damage and we attempted to remove it with the help of the Hawaiian biker handyman.

We easily had enough tools between my Bandit’s bedroll and the doctor’s tool bag. Concern grew as we discussed our issue with other riders, and Ted Sands, from Performance Machine. “Did you powder coat the wheel?” Christian scored a couple of late model Twin Cam, 1-inch axle mag wheels, powder coated them, and replaced the bearings with ¾-inch axle jobs, but there was some question about the internal spacer. The spacer needed to be solid against the inside bearing race, and that didn’t seem to be the case. The left bearing demonstrated serious wear. We started to make calls.

The Mudflap Girl bike handled the roads to Mammoth extremely well, although we are hoping to step up and buy another RockShox with at least 2-inches of play and a 250-pound rated spring for testing in the future. I’m sure with the correct resources, we can make this girder ride like a Cadillac. I ran into one problem with the Mudflap girl. The left stock H-D foot peg with massive rubber padding for comfort, wanted to slip off the stem and depart. I thought this bastard wouldn’t budge, but I continually fought it.

We called for local bikes shops, but it was Saturday night and resources were limited. Christian made a run on my FXR to an auto parts and bought a jug of bearing grease, a spray can for chain-styled foam lube, and a small container of Buffalo-snot glue for my peg. I actually needed rubber cement, but gave it a shot.

“The FXR Chopper is one great looking scooter, with just the right stance to have attitude, without being obnoxious,” said the Doctor. “Everyone twists their neck when she goes by.

We operated as best we could on the doctor’s wheel but could not remove the bearing to correct the inner spacer problem. We packed that bastard full of grease and called for a U-Haul truck rental in Bishop for the next morning. The final question: Could, would, should the good doctor risk riding his Bessie down the hill? We confirmed with U-Haul; the regional office would open at 7:00 a.m. The Bishop franchise opened at 8:00 a.m., and a 14- foot box truck was available with a ramp. We would need to score a batch of tie-downs.

We returned to the Westin to hang with our brothers, Buckshot, a Bikernet and Thunder Press contributor, and Marilyn Stemp, the editor of Iron Works. That’s when Ted Sands told us about the drawbacks of powder-coating the interior of late model hubs and the impact on bearing spacers—bad news. I rode the FLH, and it rattled like marbles in an empty tin can, but I didn’t sense any grinding in the bearings. I didn’t want to make a recommendation. This had to be his call. Then I mentioned the 40-mile distance to Bishop. He was thinking 100 miles to Lone Pine.

By the way, we gassed in Mammoth for another 98 mile run. My bike was feeling the pain of reduced oxygen at 8,000 feet, and the night would drop to 41 degrees, but she still ran well. I struggled to squeeze the nozzle into my tank and loaded it with 2.5 gallons (39.2 mpg), and the doctor refueled with 3.2 gallons (30 mpg). He will look into a jetting change for his S&S carb.

As we hit the hay, the doctor decided to attempt the slow ride to Bishop. We set the alarm for 6:30 and tried to sleep.

The weather was amazing, just a tad cool in the morning as the sun slipped between pine needles to warm the streets. We packed and rolled down the hill to the first coffee shop. We were gassed and ready for the 40-mile delicate, risky ride to Bishop, a town of 5,000 along 395 just below Mount Whitney, the highest mountain in the continental United States. We were so focused on surviving the Bishop run, we didn’t think about the cool breeze, my wandering peg rubber, or any distraction. I’m sure Christian was as tense as an over-tightened drive chain as we rolled serenely down the mountainside onto 395 south at 45 mph.

“Going 40 miles down the hill towards Bishop was a bit nerve wrecking, since the bearings were grinding and clackering like marbles in a bag being tossed on the ground!” Said the doctor.

The good doctor rode almost 20 miles, his hands, like vice-grips on his bars waiting for the bearings to scream and spit from their housing. The hefty front mag would wobble, then lock against the twin Performance Machine 4-piston front brakes and scream for relief, maybe locking up and tossing the doctor and his gear in the weeds. I asked him to ride on the right for easy access off the road, just in case.

“But after about 20 miles the sounds and noises started to be less and less,” said the doctor. “Once we got to Bishop it had subsided 80%!!!!!”  

We arrived right on time, and spotted a women in the U-Haul yard. “They don’t open until 11:00.” Her husband arrived and confirmed the bad news. Disillusioned, we rumbled into town for a hearty breakfast at Jack’s and made a number of phone calls. If we could make it to Mojave, we could find another U-Haul, but then we would only be 100 miles from home. The Doctor could ask his girl to meet us there with a trailer. He called U-Haul, bitched and sought alternatives. None were forthcoming.

We said, “Fuck it,” and kept rolling. With each 50 miles, his confidence grew, but we remained at a mild pace of 60 mph, them 65. I finally got fed up with my spinning peg rubber and pulled off the side of the road and strapped it down with tie-wraps, pulling them damn tight.

“Do you want to cinch them down with a pair of pliers?” said the good doctor.

“Nah,” I responded. “We’re good to go.”

Yeah right. The sonuvabitch still squirmed and tried to escape. At the final refueling stop in Mojave, I broke out the pliers and pulled those tie-wraps as hard as I could. The bastard never moved again.

The doctor, comfortable with his FLH, resigned himself to flying into LA by himself. I would cut off at the 210 and dodge the rough, jagged, concrete 405, heading directly into one of the most congested intersections and construction zones in Los Angeles, the 101 junction, over the Sepulveda Pass to the 10 Santa Monica interchange. I could fly into the city on the foothill freeway against the San Gabriel Mountains into Glendale, cut south on the Glendale freeway for just 10 miles and pick up the 5 for one mile before I jumped onto the 110 south directly to my door through downtown Los Angeles.

As I peeled off the 5 at the 210, Christian gave me a final thumbs up and rolled into congestion for just another couple of miles, then cut off at the 405. It was just about 3:00, the bewitching hour, before a city of half-drunk yahoos, talking on cell phones and playing grab-ass with their girlfriends, headed home from barbecues, weekend camping beer-soaked outings, cantinas, bars, ballgames, you name it. This is the most notorious crew of inexperienced drivers, on unfamiliar freeways, buzzed, and distracted, heading home after too much fun. This group of millions, in tin overseas boxes and SUVs, with stereos blasting, is in contrast to commuter traffic, made up of professional, daily migrants, who know every inch of their incessant trips back and forth to work.

Both Christian and I have ridden LA freeways for over 35 years. We both rolled into our respective digs within 20 minutes of each other and checked in. Within an hour and after my first Jack on the rocks, I wrote some compliments and foreword thinking thoughts to Paul Cavallo, the Spitfire master, and he immediately responded:

“Hey brother, good to hear from you. Glad you had a great ride,” Paul wrote. “I have you covered on the oil cap. I just finished up a re-design on the girder trees that eliminates the shoulder bolts. I will update yours to the new gear.

“Bill Dodge rode his out from Kentucky for Born Free, and loved the ride, but after a 5,600 mile round trip, those little thrust washers wore thin. I doubled the strength of all of the pivot components, and machined pivot pins into the trees, and cross bars. I even designed a retro kit for all of the existing front ends.”

We discussed RockShox with increased travel, and I also mention raked trees for better cornering. The more you rake a bike, the more it wants to go straight, which hinders cornering. Bikers generally love to corner, and I discovered, with my blue flame that even a chopper can corner with adjusted frame geometry.

“When I update your front end, I will give you 3, and 6-degree links for it,” said Paul in his response. “The girder is so easy to change the rake on.”

There you have it. The first 700-mile distance test of our Mudflap Girl FXR. Scooter Tramp Scotty is right on: Evos Rule and Choppers never die.

Oil tank and lines were next on my agenda. I opted for a more modern spin on oil filter adapter, it looks nice and makes oil changes a snap. I kept the original oil filter that was polished just in case the owner wants to go all original some day.

The front forks have been completely rebuilt with all new modern seals, I had them polished also, looks nice! My customer decided he wanted a old school look on the wheels like they did in the ’30s and ’40s, so we blacked out the spokes and hubs leaving the star bearing plates and lug bolts the original parkerized coating.

Just about everything that is aluminum was polished like chrome. We kept to the OEM look on the primary and oil tank, which was black with touches of chrome.

As for the clutch shift linkage (mouse trap), it also was completely gone through and restored, polished and looks like new. I did find out why they call it a mouse trap! Got my Fuckin’! finger snapped twice while trying to adjust it, IT HURT BAD!

The brakes have all new shoes, lines and fittings. Front brake is mechanical and rear is hydraulic, all juiced, adjusted and ready to go. Tires we picked are replicas of the day. They are Shinko reproduction white walls. Not the best, not the worst, but fit the budget just right. They have all new tubes, rim belts and have been balanced and trued by me.

The new exhaust went on comfortably with new head clamps. We kept the original muffler. It was salvageable. All the footboards have been rebuilt with new rubber and rivets and foot controls were installed.

The original generator in chapter 3, was a no go, it had a bad armature and wasn’t cost effective for a rewind. So I ordered (cust. request) a new 6v generator with built in voltage regulator, it too looks very nice. Just a quick rundown, the electric system although all 6v, has all new solid state components i.e. electronic dual breaker distributor with a solid state voltage regulator, no mechanical parts.

The electrical has all been installed and wiring is complete less the head light and tail light. Both electrical junction boxes have been rebuilt with new insulators and wiring harness.

There’s a lot of little things like the $5 chrome chain guard I found at the swap meet and some odds and ends I also found in good condition cheap, at the swap meet. You can see them in the photo’s if you look hard. The steering head lock was a nightmare. It took me months to track one down on eBay. Shortly after I purchased the one on eBay, JP Cycles informed me that they finally had one in stock, go figure!

Here’s a link to the last chapter: http://www.bikernet.com/pages/Mudflap_Girl_FXRs_Part_8_Wiring_World.aspx

What a year, and we’re cranking on so many two-wheeled fronts. Both Mudflap Girl bikes are running and one is in the wind, but I’d better back up. You’re going to love this tech, and the ending.

I took the Mudflap Girl bike to Saddlemen during the holidays, at just the wrong time. They faced the holiday schedule, then dealer shows, including the Easyriders V-twin show, then Daytona, before the dust settled and the shop was calm enough to focus on a couple of custom seats.

Sure, the economy sucks, but you wouldn’t know it if you stumbled into their brick manufacturing facility in a Los Angles industrial community. The shop is cooking, building twice as many seats as last year, and adding 420 new seat part numbers. Tom Seymour, his partner, Dave Echert, and Avery Innis have stepped into the luggage arena for touring bikes, cruisers, and sport bikes. They designed a line of bag inserts, sissybar pads, tank and fender trim, you name it. If you’re going for a long ride, they have the product for you.

That’s just the tip of the chrome and leather iceberg. The Saddlemen team will attend 78 shows, and events this year, from Sturgis to flat track racing, with the marketing director, Ron Benfield in the lead. The family atmosphere in their facility started to impress me after a couple of visits. I met 25-year team members and their sons and cousins. In fact, Avery kindly took a liking to an old Bikernet buddy, Buster Cates, and offered him a position on the team. Buster owns and rides our Shrunken FXR to work every day.

Let’s cut to the seat-building chase. The Saddlemen team turned motorcycle seats into an engineered art form. They don’t just make cool seats but poured engineering into the mix for comfort and long-ride ability. They studied the use of medical gels, then the spinal relief channel, lumbar support, and foam and fabric functions. Now they make heated seats, and the heels-down seats for shorter riders. Several of these elements add time and substantial cost to the seat manufacturing process. Plus they always attempt to make their seats fit better than stock.

Saddlemen has a team of custom seat builders who carefully design seats for special applications, race bikes, and sometimes, ultimately production seats. I was impressed with the myriad of seat manufacturing processes and how the team handled each one. Jose, the senior custom seat designer, worked with us through the entire process. First, he verified the position of the seat and the position of the frame rails, which are not always entirely symmetrical. Then he determined the center of the fender. He carefully masked off the entire seat area, and then began to hand-form a sheath of 1/8-inch wax. It performs a couple of functions. First, it molds perfectly to the frame, and second, it affords a 1/8-inch clearance for fabric to fill during the final stage.

“Every motorcycle has a seat,” Avery said, “but there are multiple body styles.” Avery is the engineering, design, and customer relations guru. He worked for Suzuki and Honda for years, and rides touring bikes and enduros. “All body styles don’t fit the same seat or style of riding.”

The wax helped the seat to locate itself on the frame perfectly. With wax strips, Jose formed a small channel on the inside of the wax seat pan to allow for fasteners not to protrude. The channel is about ½-inch wide and 1/8-inch thick. When the channel was placed securely, Jose filled the wax-to-wax edges with clay to prevent resin from seeping under the wax channel.

After the first sheet of fiberglass was carefully laid over the wax and carefully coated with resin, we cut a dusty trail and planned to hook up the following week.

Day Two:

We returned to the shop. The doors open at 6:30 in the morning and shut down at 3:30. I found the timing to be very civilized. The staff can enjoy a comfortable afternoon at home. We didn’t roll into the shop until 10:00 and Jose was already cutting and shaping the fiberglass seat pan, with the seat hook brackets molded into the bottom of the pan. Fiberglass contains amazing strength, yet adds flexibility. They are the official seat maker of the AMA pro racing/flat track, and now road racing classes, and they make all of Steve Storz café racer kit seats for Sportsters. They also sponsor dozens of flat track racers, the 5-Ball Bonneville Racing team, the Jordon Race Team, and Lotus.

With the seat pan shaped perfectly for my goofy Mudflap Girl ignition key system, we peeled out once more, and returned the next week for foam shaping.

Day Three:

“This is the most impressive aspect to making a custom seat,” Buster said of the foam shaping process.

“The driving force is style,” Avery said, “then we add performance with the gel, the spinal relief channel, and lumbar support.” Initially, I shot for the coolest, cleanest design to feed my chopper soul, but realized I needed a long-distance rider for my future Sturgis runs. When the discussion of lumbar supports surfaced, my lip zipped tight. I didn’t want to step into the middle of the comfort engineering mix.

My goofy key position worked perfectly into the channel design. Jose cut and shaped the 1.5 inches of foam with highly sharpened kitchen knives and coarse emery discs. Avery and Jose discussed the sketches for the position of the channel and the gel. One inch of gel represents 3 inches of foam.

Here’s the company’s gel description: Almost two decades ago, Saddlemen was the innovator of SaddleGel for motorcycle seats, bringing over a gel technology widely used in medical applications.

Without question, SaddleGel is the most important breakthrough in motorcycle seating technology in decades. This amazing product will increase the amount of time you spend on your motorcycle, creating the comfort necessary to ride all day. Every type of riding is more enjoyable, from touring to dual sport, canyon carving to street cruising.

When it comes to motorcycle seat comfort technology, nothing compares to a Saddlemen seat with SaddleGel. The proprietary SaddleGel technology was gleaned from the medical industry with specific origins in wheelchair pads and hospital beds. The gel was used (and still is) to prevent bedsores for those confined to beds for long periods of time and for people in wheelchairs—some for their whole lives. Know anyone that rides as much as a person confined to a wheelchair?

In the early ‘90s, the experienced riders at Saddlemen figured out a way to incorporate all the benefits of gel into a motorcycle seat and quickly learned it was far more comfortable than standard seats for a variety of reasons. For one, SaddleGel isolates engine and road vibration, a common cause of rider fatigue. SaddleGel is a molded solid with fluid-like properties that will not slide to one side or move around in your seat like air or water in a plastic bag. Instead, the proprietary design eliminates pressure points at the hip bones and tail bone by evenly distributing your weight across the surface of the seat. Otherwise, pressure points or hot spots can hinder blood flow, causing pain and discomfort. Normal circulation is never lost on a seat with SaddleGel. It keeps your rear end comfortable on a long ride, and ready to respond quickly as road conditions change.

Saddlemen SaddleGel is extremely advantageous, but we were able to maximize its benefits by developing a seating comfort system around it. Our integrated seat designs include a selection of materials that work together to make our seats as comfortable as possible, while still giving your bike show-quality style.

Avery has a product formula he learned from the president of Suzuki in 1990 at a business philosophy conference. “Every product must be evaluated for styling, performance, and value,” Avery said. We discussed business notions and the alignment of the stars while Jose carefully shaped foam.

Day Four:

While I was missing in action, Jose refined the shape, inserted large segments of gel, and made a custom aluminum channel section. They need something to apply the upholstery to, and then fasten it to the bottom of the seat pan. Nothing is as easy as it seems. Then he added a final lather of breathing foam, only about ¼-inch thick, and we started to decide on the fabric and pattern.

“In the past, we all thought leather was the ultimate fabric,” Buster said, “but not so.” Learning the Saddlemen ropes fast, Buster discovered new, more resilient fabrics, stronger materials, and more comfortable weaves. Avery chose a long lasting carbon fiber weave for the front of the seat panels, then a brushed aluminum vinyl for the channel center and the lumbar region. They even planned to scan a Mudflap girl and embroidered her into the seal. The rear seat tab was positioned during the second layer of fiberglass. Avery chose another black vinyl for the back of the seat. It’s tough, has the delicate touch of skin, and will last.

Jose marked lines for fabric patterns, and next he would drill and counter-sink the custom aluminum panel before upholstery and placement down the center of the pan. He ensured that the gel was properly glued with their coveted water-based adhesive, used for all foam application. The thin layer of porous headliner foam acts as a visual detailing source for seat shaping and adds breathing, but it’s not long distance comfort foam. The Saddlemen-designed progressive foam and gel handled the tough job.

Here’s the Saddlemen description regarding the spinal channel system: Our Gel Channel line of seats for sport bikes are designed specifically for the rider that needs a seat that can do everything—canyon carving, track days, or commuting.

They feature Saddlemen’s Gel Channel (GC) technology (patent pending) that incorporates a split piece of SaddleGel and a channel in the base foam to relieve seating pressure on the perineal area, increase blood flow, and keep the rider in the saddle longer.

While another week sped past, the Saddlemen staff sewed the pattern pieces together with marine grade nylon and polyester, colorfast thread for sun tolerance and lasting durability.

I never imagined so much thought, engineering, product testing, selection, and creativity would go into a goddamn seat. But when you think about it, you’re almost as involved with the seat as you are with any other aspect of a motorcycle.

The call came: “The seat is finished and fine,” Buster said. “Come and get this puppy.”

We grabbed the new license plate, a new Aeromach mirror, a Bandit’s Dayroll packet full of tools, and peeled out. This wasn’t within the mantra of the Eddie Trotta break-in procedure. The well-organized Saddlemen facility was located about 10 miles from the Bikernet Interplanetary headquarters. We ran the driveline through several heat cycles, but it never felt the clunk of the BDL clutch allowing the JIMS 6-speed transmission drop into gear, or the Metalsport mag wheels and Avon tires skid across any dusty asphalt lanes.

The Mudflap Girl resided in the asphalt driveway, out front, as we pulled up to the Rancho Dominquez facility. For the first time, I swung my leg over the carefully detailed Saddlemen seat, and sat down, as if about to cut a dusty trail. I immediately felt at home.

While the Saddlemen gang hung out around my Mudflap Girl in their driveway and we warmed the H-D Evo engine, we tightened the leaky fuel filter, adjusted the position of the clutch lever, and then I dropped it in gear. It shifted so smooth, I didn’t know I was in first. I was slightly nervous as I rolled out of the driveway. The seat was amazing, but would I survive the virgin ride home?

Next, we will cover my son’s final build aspects, adjustments, and first ride. Hang on.

Editor’s Note: Our 5-Ball factory racer was feature in Heavy Duty Magazine in Australia recently. It’s the largest selling custom bike mag Down Under. The story and the photos were handled by the amazing Smilin’ Doc Robinson, the longtime tech editor. I’ve left the story alone for your viewing pleasure. Enjoy.–Bandit

Many interesting and colourful characters populate the biker world and Keith “Bandit” Ball walks tall among them. And not only because he tops out at six-foot five inches. Lifetime biker, author, longtime Easyriders’ editor, custom bike builder, salt racer, founder of the premier web site Bikernet.com, Bandit is all this and more.

Get him settled in the comfortable lounge seat in his Los Angeles abode, pour him a stiff whisky, and sit back as he shares tales of the road, some that would make your hair curl, others that are genuinely side-splitting and always among them, lessons to be learned about life.

I figured that the best way to introduce this build to HEAVY DUTY readers is to give it to you in Bandit’s own words: “For decades guys have built vintage- looking scooters with late model drive-trains. Hell, I built another one at Strokers Dallas in the ’90s. Before I dreamed of it, Arlen Ness built a ’20s vintage scooter and sidecar around a Sportster engine.

Randy Simpson built vintage kit bikes. Don Hotop built some of the finest vintage-styled customs and recently I saw a ’20s styled bike at the SEMA show in Las Vegas built by the Shadley Brothers for House of Kolors. Beautiful piece. So I ain’t the first by a long shot. But there is something in the air recently about respecting the old iron and bringing it back to life. Some of it has to do with restrictions, and building older bikes is unrestricted. Some of it has to do with nostalgia and some is just a wild departure from the last project. I’m excited every year about this learning process.”

I asked Keith to sum up the vision that drove this build: “Well I built it in the teens vintage style, but with my height and long limbs I had to scale it up a bit. It’s built for long miles, with floorboards, a sprung seat, rubber grips, tall gearing and a spare gas tank. Every custom motorcycle build is an adventure. It takes me from one crazed time in my wild life to another. Fortunately, I’m not spilling my guts about another woman I lost during a knuckle-busting build. But this build did represent turning points. I’m rapidly closing in on my mid-sixties and about ready to sign up for Social Security. It also represented our stinky economy.”

Bandit is such an industry icon and it is not surprising that many of the leading lights of the motorcycle aftermarket were involved in this build, blokes like Ron Paugh of Paughco, leading manufacturer of custom parts and accessories for the past forty-three years, Rick Krost of US Choppers, Chica, who needs no introduction, Gard Hollinger of LA Choprods and HEAVY DUTY photographer Glenn Priddle who made the sweet seat.

Here’s Bandit again: “The key to the success of this project is the drive train. I sought a Crazy Horse V-Plus, 100-inch engine for several reasons. It has a classic design, renewed performance, cool looks and a left-side carb. I coupled it to a JIMS 5-speed transmission with a Baker kicker unit and Baker N1 shifting drum, so I can run the tank shifter and find neutral without a problem. The rocker clutch system I put together from old H-D parts while I fabricated the tank shifter.”

When he hasn’t got a fast motorcycle between his legs, or a whiskey in one hand and a beautiful redhead in the other, Bandit is happiest welding, soldering, wrenching, milling and turning metal in his secret and damn well-equipped lair beneath Bikernet HQ. His other love is writing, usually upstairs in his 1923 shop, behind his glass-topped Panhead-motor desk, rattling his computer keyboard, churning out another fiction book, a book for motorbooks, magazine articles (sometimes for HEAVY DUTY), or news, or one of dozens of tech articles for Bikernet.com.

And for those of you who are truly interested in the real guts of bike building, let me recommend reading the whole story of this build on the Bikernet.com web site. It runs over some eleven parts and is well illustrated with photographs showing each and every step of this build.

If you only read one part of the full story, make it Part 6 where you’ll see the immense amount of work that went into the rear fender fully detailed as master metal shaper Chica gets to work. But once again, I strongly recommend you read the whole thing as a salutary lesson on just what goes into a ground up build. Without the space limitations of a magazine Bandit is able to show and tell stuff that you won’t find elsewhere. To find it, go to Bikernet.com and click the Free Departments button and select Techs and Bike Builds and scroll backward through the various articles until you find Part One and take it from there.

I really dig this bike in every aspect; the concept of honouring old iron in this way, the marriage of old school looks with a nod here and there to practicality and safety, given that brakes back in the first two decades of the twentieth century were mighty primitive to say the least. I love that shifter in all its brassy mechanical glory, the vintage touches like the chain oilers and the leather strap holding down the battery and the cool fuel tank mounted up top to extend the bike’s range.

Having examined it closely, both during construction and in its completed state, I can attest that the fit and finish all over is excellent and detail touches like the pin striping are icing on the cake. Keith thanks Sin Wu for her part in this build and reckons this woman is a keeper, and I can understand that. This bike is a beauty and will look just as cool in fifty years from now. Way to go Bandit, I’ve seen several of your other builds but with this one you’ve climbed a pinnacle. HEAVY DUTY is proud to feature it in our pages.

The plan was to ride to Sturgis, but I never got out of Dodge. Now the plan is to ride it to Arizona for the too broke for Sturgis run to Salome, a little sun burnt town in the middle of nowhere. But it has a very cool or western saloon on the edge of town.

Wiring is always a treat, unless you use one of those systems in a box like Phil’s speed shop systems. I ran one on my factory racer, and it was a breeze. I’ll try to find a photo. It was designed to mount to the frame seat post. Inside it contained the circuit breaker, the starter relay, the ignition switch, the starter button, high low beam, and horn button. Then a ream of wire rumbled out of a hole. I guided them to the appropriate spots and hook them up. Nothing to it.

In this case, we worked with Wire Plus since they are the masters of wiring kits, Speedos and assorted equipment. They sent me a complete wiring harness with a starter relay, flasher system for turn signals, a 30-amp circuit breaker with mounting strap and rivets. They also included an installation and operator manual for model Wp192, Mid Frame Mount System, with Chopper style harness, with or without turns.

Their manual affords the reader a lighting circuit flow chart, an ignition flow chart, and an accessory flow chart. It demonstrates several ignition switch wiring circuits and handlebar circuits. It even comes with a Wp143 lighting control system for auto-canceling style harness. Actually, I checked the Wire Plus web site and they do make a seat post ignition switch wiring system unit, in a coffin shape, classic, and old school. They also make a cylindrical shaped engine mounted ignition switch housing, and ignition and toggle switches. They have systems that include compression releases–Amazing.

Wire Plus also makes individual wiring products, like their lighting control modules, power modules, plus custom power ports, for plugging in accessories. There’s a reason for going on and on about Wire Plus. Wiring can be a nightmare, and I’m a lazy. I want to be as minimal as possible, for ease and reliability, but I’m fulla shit. Just about the time I think I need to cut turn signals out of my system, someone is wiring in heated grips, or a heated seat, a some sound system, or neon lights under the engine. I avoid anything extra, like the plague. Hell, wire plus make engine mounted electrical port systems, so you can plug in your heated vest, helmet sound system, or whatever.

This is going to be a terrific test. My son’s bike will contain more bells and whistles, and Grip Ace controls in the bars. Tim from Grip Ace from Rivera is coming over to show us how easy it is. On Frank’s bike, we will install turn signals, so anything is possible. We will also wire a metric bike, the XS Yamaha bobber. So, over the next couple of months you will witness three variations, with Wire Plus products.

I start wiring by finding all the components and placing them somewhat in position. Then I search for a place to hide the circuit breaker and a circuit board, or bank of connections. First, we made a trip to the local Marine store and ordered an ignition switch. This included a starter switch, but we were using the Spyke push-button starter mounted to the solenoid. It eliminated the starter relay and any starter switches.

Once I determined a handy location behind one of the Mudfap Girl FXR panels, I drew up a wiring schematic, while referring to the Wire Plus handy manual for guidance. I came up with this nuts notion of hiding the ignition switch under the seat nose, which would position it perfectly for some of the wiring, and run some of it through the backbone of the frame. I grappled with a mounting notion, but Danny came up with the final notion, which took a lot of work, but was highly secure.

Wire plus makes several digital speedos, and several mounting systems for different applications. It was a breeze to mount and wire once I found the mysterious neutral switch connectors, which I ordered from the factory. The WP speedo mounted like a dream on the bars, once I plugged the wiring harness into the rear of the unit, ran the wires under the tank, back to the nerve center for power, then to the speedo sensor, and the neutral switch. Nothing to that one, although I wouldn’t mind running the wire loom through the frame in the future.

Since I was thinking about the rear brake pressure switch, I started to work out my GMA brake systems, and we made some measurements. I ran over to Baker Performance products and in five minutes we had new brake lines cut to size. This was probably the easiest bleeding process I have ever encountered. They were bled and working in no-time. Unfortunately, GMA doesn’t make a clutch lever to match.

On rubber-mounted bikes, I run two grounds. I welded one to the frame and I use one of the Spyke starter mounting bolts as an auxiliary ground. I don’t want to take any chances with the charging system, or the ignition system missing a grounding connection.

I needed to mount an On-On switch in the headlight bucket. It took some hunting for the correct sized switch, then a headlight seal beam from Biker’s Choice, and a lot of digging for a three blade connector. My headlight came from a spot on a police car in the ’30s.

Almost all of my electrical components came from Spyke or Compu-Fire. The Compu-fire ignition system is a breeze. This time I’m running a Compu-Fire single fire ignition system, with their single, dual wound coil, which mounts between the heads, in the standard stock position. It’s all too tight and convenient. Two wires to the coil and one to power and the system is good to go. It’s about that easy to time.

My son showed up with the missing parts for his Bub Bare exhaust system, and we started mounting it. I wish the exhaust guys would make kits with the flanges and retainer spring rings. Some systems come complete, but it’s a drag to run to the dealership, when you’re ready to rock. I understand why they don’t supply them with many system. If the system is replacing a stock system, we just switch out the parts. And these four pieces would jack up the price, but give the customer the option, and the manufacturer could make an extra buck and save the builder time and hassle.

This system slices damn close to $350 and you paint it with whatever heat paint, or heat wrap you like. It’s very similar to my D&D system.

I couldn’t think or speak. I had a week and a half to insure that this puppy ran. I could sense fangs growing under my upper lip. I began to snarl as my fingernail extended beyond my cold hard hands. My eyes reddened, and I wanted to ride. Without the throttle cables I could use the cruise control, if it still worked. I could jam it into gear and fly. Frank hit me with a torque wrench. “We’re burnin’ daylight,” he snapped, “Let’s measure the cables and install the left Knuckle style grip.”

After wiping the grip end of the bar down with alcohol, the grip interior was coated with the rubber cement, that came with the grips. Then it was immediately slipped into place.

I snapped out of my Werewolf London fog. We measured the clutch cable then compared our findings with the throttle cables. As I suspected, lucky 13 inches to make up for the 12-inch taller bars that were an inch wider than the stock units. Frank made a B-line for the phone to call Barnett’s and ordered the cables. We were scheduled to roll up to the fleet center for a performance upgrade on Friday. It was Tuesday and the cables wouldn’t arrive until Thursday. It was going to be a close call. “Barnett has been around since Moby Dick was a minnow,” Frank said. I’ve been ordering custom cables from them since I was in my 20s and first influenced by Apehanger madness. “They are as reliable as the sun on the coast,” Frank continued, but I was still nervous.

We weren’t done yet. We torqued (15 foot pounds) the bars into place and began to cut and fit Goodridge brakes hoses, distributed by Barnetts and Custom Chrome. Another delicate operation.

The King has dual disc brakes and the fittings had to be installed just right, tightened properly and finally torgued into place. From the bottom of the triple-trees we used the stock measurement to the calipers from the existing junction under the trees. The new lengths of Goodridge hose were cut with the largest, strongest side cutters I had. Before any fittings were installed we slipped a 2-inch piece of black 3/8-inch diameter shrink tubing over the hose. Next a chromed pinch fitting was slipped over the cable. Frank brought the tools and supplies including a tool to spread the braided hose after the rubber housing was stripped away to allow the new fitting to be installed.

Stripping the rubber sleave back from the end about an inch.

Here’s all the components involved in the process.

The tool used to spread the braided steel shield.

Then a small brass round furl (like a brass ball-bearing with a hole in it) is slipped over the plastic lining. It must be pushed to the point where the internal brass ridge meets with the end of the plastic liner. The other half of the fitting with the long tube is shoved into place. In each case we clamped the fitting between two sheets of leather then began to tighten the sleeve onto the fitting. In each case they were a bear to tighten down indicating that we had succeeded in a strong, secure grip.

The spreading process involves shoving the tool into place and swiveling it to make sure the braided area is spread consistently.

Installing the furl is simple, just slip it on carefully then push it into place. But, inspect the inside to make sure the plastic hose is against the interior ridge.

Now tighten the pinch fitting. Note the leather pads in the vice to prevent damage to the banjo fitting. These puppies are tough to tighten down, take your time.

Here’s another way to hold the banjo fitting for final tightening. Be careful not to bend or damage the sealing surfaces.

Note the two bronze washer/gaskets on either side of the banjo fittings for proper sealing which is critical to your brakes.

After each line was carefully constructed, they were installed on the bike after some jockeying with the Goodridge billet junction under the tree which fit precisely.

For some reason, this Goodridge junction mounted extremely snug between the fork tube guards. For awhile we thought we were in trouble.

We followed the original routing of the stock brake line through the nacelle. With the lines in place we torqued them down (17-20 foot pounds). I took the easy way of bleeding the brakes. I pulled on the lever gently allowing the bubbles to pass through the master cylinder. It took a while, and I had to keep filling the reservoir as the the lines drained the supply.

We used the stock 12-point fittings which torqued down easily to 17-20 foot pounds, which seemed like a lot.

We had completed all that was possible for Tuesday and I swung my leg over the saddle once more. As fire and smoke poured from my ears Frank crept out of the garage and into the night.

Thursday morning I paced the vast porch in front of the headquarters waiting for the UPS man. The truck sped past without a hint of slowing. I called Frank, he called Barnetts. I called the Fleet center after finding that the cables wouldn’t arrive until Monday morning, guaranteed. We had an American Rider magazine deadline, but more importantly I had a run-to-Arizona-deadline for the following Friday. I started pacing the garage and bowing to the new 16-inch apes. I knew, by the power of the Ape, we would succeed.

At 9:00 a.m. in my boxer shorts, Monday morning, I met the UPS man and signed for the Barnett package. I started to lube all the cables then decided that I should get dressed.

In order to install a new clutch cable the face of the transmission must be removed. I was surprised that this was the first item that I ran across on the King that was a pain in the ass to install. The entire exhaust system had to be loosened all the way back to the rear muffler isolator. before the clutch release housing could be removed.

With large clip ring pliers the throw-out mechanism was set free to release the clutch cable which virtually snapped into place. Then the cover was spun to allow the cable housing to unscrew. Next the new cable was fed along the same route as the stock job.

Once the clutch release cover is removed and the clip ring snapped out, you can see the outer ramp with the coupling ready for the cable.

If you look close the cable has been fed through the hole and is heading towards home.

Now with the new cable attached the outer ramp heads back into position. Watch you don’t tilt the case. The ball bearings will escape.

This shot shows the entire clutch release assembly complete. Remember as you reposition the clip ring to put the sharp edge up for the most secure bond.

We discovered that we had a lot of slack and rerouted the clutch cable outside the front motormount to eliminate some. Then the tranny cover gasket was wiped clean and the cover replaced (torqued to 10-12 foot pounds), then refilled with tranny fluid to the appropriate level with the bike upright and the dipstick threads just touching. We filled it to the top dipstick mark, about 3/4 of a quart capacity.

With this assembly you spin the cover onto the cable, not visa-versa.

According to the book, the torque specs call for 10-12 foot pounds of torque to snug up the clutch release cover.

With a 9/16 box end wrench snug the cable housing down with a new o-ring attached.

We jacked-up the gas tank to afford us access to the fuel injection throttle cable routing. With the three tank mounting bolts removed the tank was lifted easily until a chunk of wood could be wedged under the front of the tank. Then I figured out which cable was what. With a small Crescent wrench, I loosened the throttle cable adjusters and took out all of the adjustment to allow lots of cable slack.

The unit with the small spring around the cable at the throttle body end was the push cable. I fed the braided cables through the runners as if they were stock cables. You will note, if you attempt this, that there is a Cruise Control connection in one of the stock cables at the neck. We unplugged it with trepidation. I wasn’t sure what havoc it would cause. I hadn’t tried the Cruise control. As it turned out, it’s a sensor to kill the control, if you back off the throttle abruptly.

Lubing throttle cables starts with wrapping the cable housing with a little masking tape to create an oil container. Fill it with a light 3-in-1, silicone, or Marvel Mystery oil and let it seep into the housing. Fill it several times.

Feed the cables up through the throttle casing. With a little force they will snap into place.

Make sure to grease the brass barrel before installing it to the cable end. The grease will help hold the barrel in place.

With the Barnett cable set at the most slack position, slip the barrel and cable onto the greased throttle guide grove.

This is not a good shot of installing the cables into the guide slots in the intake module, but it’s easy. Just make sure you have the right cable in the right slot. It doesn’t hurt to grease them which we forgot.

Here’s the cables in position. That odd short cable on the side is the cruise control job.

Make sure you oil the throttle cables before they are snapped into the throttle housing on the bars, because the spring clips that hold them into place are a bitch to remove. The cables were both put into place with brass rollers, “After you grease the throttle and cable runners with a Q-tip,” Frank reminded me. Be careful not to lose those tiny brass suckers. I was told later to try to adjust the cables evenly under the throttle and make sure you have slack in both lines so you don’t have continuos drag on the cable fittings.

Here’s the throttle body in place waiting for the front brake mastercylinder.

According to experts, you should adjust the cables so that the adjustment screws are approximately equal in length. My adjustment had to be straightened out at a later date.

Finally we replaced the air cleaner backing plate using Phillips screwdrivers to hold the gasket in proper position. Next the breather hoses had to be pushed onto the head fittings and lined up with the air cleaner element. Lastly the cover was installed. It was time to ride.

But not so fast Kimosabe. We had to install the riser cover, the nacelle trim and the headlight assembly. We were hauling ass.

The actual breather fittings hold the air cleaner backing plate into place.

Use small Phillips screwdrivers to hold the air cleaner gasket aligned.

Push the hoses into place keeping in mind that they feed into the air cleaner element.

This little nut and screw are a bear to replace but must be handled before the nacelle strip can be installed.

This slightly out-of-focus shot shows the little stud that slips through the nacelle. Make sure the strip is locked into the riser cover slot before you tighten the nut.

Tighten the nut lightly with blue Loctite to keep it from rattling loose.

Don’t forget to plug the headlight in before you install it, like I did.

Install the headlight assembly with all eight black screws. Leave the bright adjustment ones alone, unless you lowered your bike. Then it needs adjustment.

We could screw the riser down with the Phillips screws and replace the snap-on ignition ring last. I still don’t like the way it fit and need to check it again.

By noon on Monday we had completed the Highbar installation and I was itching to hit the road. We had moved our appointment at the fleet center from Friday to Monday morning, then to Monday at noon. We didn’t roll up to their doors until 1:30 p.m. and Alan, the master mechanic announced that he was leaving at 4:00. We were burnin’ daylight once again. Would the pressure every end?

The final Frank shot with one hand hanging outside of a van window. I want to thank Frank for the use of his tools and his photographic and technical skills. Those elements and my bumbling hands make these techs as complete as they are. Believe me, it’s a bastard to build a bike, write a tech and take the shots at the same time. We’ve done it before, but a team efforts helps a helluva lot.

Next, we’ll install a performance package with Screamin’ Eagle heads, cams, air cleaner and two into one exhaust that we had jet hot coated. Hang on.
