Sturgis Shovel Part 6
By Robin Technologies |
Here we go. I’m relunctantly behind the eight ball, or more likely the 5-Ball in this case. The bike is nearly complete and I haven't caught up with the articles. For the most part I was working at Primedia on the bike mags and didn’t have time to breath. No fucking lame excuses. Let’s hit it.
My original plan called for brass sculptures to hang this bastard together in a purely Bandit way. I messed with some odd heavy brass cloverleaf rod that was over a ½ inch in diameter. I wasn’t having my usual creative luck with bending or messing with this material. Kent from Lucky Devil Metal Works in Houston recommended that I use silicone Bronze rod and I’ve since messed with it. I shifted gears from Gargoyles and sculptures to pure mechanics. I started drilling holes is everything.
I discovered a piece of ½-inch wide strap that I thought was copper. Remember that the notion behind this mess is to use as much bare metal as possible. As it turned out the strap was brass so I gave it the Scotch Brite treatment and went to work. Before I made or positioned the rear Custom Chrome chain I needed to align the wheel, the transmission and the engine. I used my BDL inner primary and pulled the loose engine and tranny into position. Then I centered my chain axle adjuster and installed the chain using the CCI instructions (above). I have an old chain breaking tool, so I took out just enough links.
With the chain in place, aligned and adjusted the wheel using the Doherty wheel spacer kit (a life saver). I couldn't mess with the requisite chain guard until all was in the correct groove. Although the Paughco custom frame is designed for a belt, I choose the old school route and it worked out well. Lots of extra space to mess with.
I dug through my drawers of tabs and crap that I’ve had around for 25 years. In the old days Mil Blair would call me from Jammer from time to time and tell me when it was time to shit-can scrap iron. I picked up tabs, spacers and brackets by the fist full and I’ve been moving them from place to place ever since. But damn, when you need a tab it’s bitchin to find just the right size in a drawer. Since I was going nuts with the drilling treatment, I matched the work on the frame with holes in the chain guard and counter sunk the edges for a more rounded look.
I also hit the top motor mount with a similar treatment. To give it a bit of consistency I measured from center to center on the holes and made all the holes the same diameter, 1/4-inch.
The hole deal became an obsession. I started drilling ¼-inch holes in everything including the Joker machine foot controls. I also went after Russell Mitchell’s Scotch Brite code. I swallowed hard and rubbed a piece of chrome with the coarse material and discovered that chrome reflects everything until it’s brushed with the wiry fabric. It gave it a raw material appearance and I decided that it was cool but a pain in the ass to do.
Again, I drilled the holes the same space apart, ¾ of an inch. It’s not always that easy, though. Sometimes the formula just doesn’t work. I use a pair of calipers to hold and mark the distance from hole center to center. If a hole ends up being located too close to an edge of the material, I back off and try another formula. Make sure to plan before you start drilling.
Here’s that damn brass stock. I was determined to have Brass, Copper, Stainless, Aluminum and a bare metal effect on the frame. You’ll see shortly how it worked out. I couldn’t bend that brass shit without destroying it, so I made the shift linkage out of it. I cut it off on a bench lathe and drilled and tapped the ends to 5/16 fine threads to fit the fine thread heim joints. Then I drilled the rod and countersunk the holes to remove the sharp edge.
Here’s one of the Joker Machine control sets, rubbed with Scotch Brite and drilled. They make fine controls, some of the best. You can adjust these puppies anyway you choose to fit your riding position, inseam or foot angle.
Before I leave this chapter I’ll touch on this new petcock from Spyke. It’s incredible, if it works well. It’s designed to give you every option for positioning and spigot direction. I ran into only one problem. No wrench lands to help tighten the bastard.
Check it out. You can run it faced in any direction and still read the switch locations and turn the knob without a lever smacking the frame and components. The spigot set allows builders to face the gas line in any direction.
I used the straight spigot and took off one of the fittings because my tank threads are female. The only problem I had was tightening it down, but I’ll get to that after the powder coating returns from Foremost Powder in Gardenia, California.
This puppy will revolutionize the industry for petcocks, if it works. I’ll let you know in a week or two.
Ride Forever,

Sturgis Shovel Part 2
By Robin Technologies |
This bike might look like shit, but it should work perfectly. I'm endeavoring to keep it light, tight, narrow and right. So far so good. We've even decided to eliminate paint from the equation, except for rusty metal that may need black powder coating from Custom Powder Coating in Dallas, and the front end was powder coated black at the Paughco factory.
Let's jump into the shop. I was jazzed to receive my Rev Tech wheel order from Custom Chrome. I needed to mock up the frame and ship an image to Tim Conder for a concept drawing. Conder's images inspire any builder. I couldn't move on it until the Custom Chrome wheels were delivered and mated to the Avon Venom tyres. I'm also going to avoid chrome and flashy stuff as much as possible. We're running bare metal in several instances: Wheel rims, aluminum tank, brass fender rails and linkage, copper hard oil lines, and thick wall copper tubing bars. Dig this, we're going to galvanize the frame, rear fender and oil bag. The XR Sportster racing tank which is aluminum was delivered from Cyril Huze. I'm going to leave it brushed aluminum, but the capacity was a minimum 1.75 gallons. I'm mounting it high on the frame so we'll open the tunnel for additional fuel capacity and weld the area shut.
I'm jumping around. Let's get back to the Rev Tech wheels. The spokes are stainless with polished aluminum rims for a long lasting approach. Even the Paughco frame came with brushed aluminum axle plates. We're going to leave 'em alone. Cyril Huze designed a new, between the heads, coil and ignition switch mount. I ordered one without polish or chrome. It's unfortunate that we can't get wheels with Stainless hubs and eliminate chrome all together. The front is a 21 with a 18 by 5-inch rear for a 180 Avon Venom. I don't want a super wide tire. I'm specifically avoiding wide tires. I think they make choppers look like fat-assed chicks. They lose their chopper code of agility and lightness.
With my Doherty wheel spacer kit I was able to set up wheel spacing quick, for the time being. It's a trick working in the shop by myself and I will try to explain some operations from that perspective. We all face shop blues from time to time. Makes me kick back and rethink various operations when six hands are needed and I'm limited to one on the part and one on the arm of the drill press.
So alone one night I grappled with the installation of the CCI neck bearings (I need a JIMS tool for the races), to install the Paughco springer front end. After a trip to a local fastener store I was able to weave two studs into the rear legs of the front end for traditional, vibration dampening Custom Cycle Engineering risers. The studs needed were 1/2 inch about 2.5 inches long with 1/2-20 threads on one end and 1/2-13 on the riser end. The shop only had two different-length studs and one needed additional tapping to fit.
I use these risers on most of my bikes because of the traditional, old school appearance and the vibration element for long runs, but they take a degree of thinking since they shove the bars toward the rider (and often the tank) about 2 inches. I needed to watch for the appropriate amount of tank clearance and ultimately needed the 1-inch longer stems. Very high bars can be a problem with the leverage against the flexible rubber, but with patience, they will work fine. Since each riser is a single unit, they will flex and pivot until they're aligned and tightened down.
I installed low rise drag bars from Custom Chrome/Khrome Works. I'll see how they fit as the seat is mounted. I ordered a seat at a swapmeet this weekend, black with brass buttons by West Eagle. My plan is to bend thick-walled copper tubing and polish it for the final bars.
Now Imagine the first time I installed the front wheel, wrestling with the slipping front end and frame, the front wheel, the axle and the spacers simultaneously. Fortunately my 11-year-old grandson was on hand with a rubber mallet to assist. For the rear I used a crate to hold the wheel and the approximate height so I could muscle the axle and spacers through to align it with the frame. It was time for a Corona.
The engine is currently in the hands of S&S for a breast reduction from 103-inch to 93 smooth inches of reliable horse power. I'm waiting on the engine build images to share with you.
Hold on, I'm slipping the clutch again. Next I mounted the Rev Tech rear wheel with another Avon Venom within the Paughco frame. Unfortunately my Kraft Tech Fender is 9-inches wide and the tire on the 5-inch wide rim runs only 7-inches. I need about an 8-inch wide fender. I'm waiting for the shipment to arrive.
Then I moved onto the tank. I needed to create a couple of bungs for rubber mounting the rear of the tank and tap them for 1/4-20 threads. It was the first time I used our new/old lathe. This is all a new learning experience at the new Bikernet Headquarters. I grabbed a lathe that was rusting in Japanese Jay's backyard. He wasn't using it and I wanted one to cut wheel spacers. I reworked and cleaned the lathe until it was operational then the Doherty crew created a wheel spacer kit? Ah, but the lathe has a myriad of uses, like cutting bungs from a chunk of aluminum. Worked great.
Then I tapped them using the lathe chuck. I discovered that the tank petcock bung needed moving to the rear, since the tank was mounted at an angle. I cut it out with a die grinder and returned to the lathe to machine off the welds.
Next I need to learn how to use my new/real old, milling machine. My dad was a machinist most of his life and ultimately an engineer in the oil well industry. As a teenager I worked in machine shops and picked up equipment experience between smoking joints. I swear I learned something.
Let's see, what else. I dug through our parts bins and found the exact bracket I needed to mount the Kraft Tech oil bag. I need to cut off the existing coil and oil bag brackets and make a new front mount.
Wait a minute I'm slipping again. I dug through my bracket drawers and pulled a couple of old Jammer brackets 1/4-inch thick. I drilled 1/2-inch holes for the rubber mount grommets from Cyril Huze. I bolted them in place.
Next, I carefully measured the backbone tubing of the frame and figured the dimensions of the tabs and carefully marked and cut them, then beveled the edges for strong welds.
The next day under a sober sky, I refit the tank, tacked and MIG welded the tabs. Once the Bill Hall, pro-welder, welds my tank bungs in place and the tunnel is capped, I can make the final rear tabs and mount the tank semi-permanently. Is that possible?
Next, I will mount the Kraft Tech Oil bag, the rear fender and sprung seat mechanism. I'm also dealing with the rear drive. The frame was set up for belt, but more and more I like the chain notion.
The JIMS machine tranny is set up for 4-speed applications with 6-speed gears. First, I ordered the wrong Custom Chrome tranny plate, then I was twisted about the sprocket vs. belt pulley needed to drive the bastard. I dug through old parts bins until I found gears, since it looked like a gear-driven job. Then the sprocket didn't fit. I'm still trying to figure it out.
I'm going to meet with Jim of JIMS in the next couple of days and get to the bottom of it.
Although the frame is set up for a belt, that means if I run a chain, I'll have plenty of alignment flexibility. Hang on for my next report.

1928 Shovelhead Project Part IV
By Robin Technologies |
One of the best aspects of building bikes nowadays is the integrity of the components. If you get the right mixture of components together and take care with the wiring and assembly, you’ll have a bike as reliable as factory stock. That’s one of the reasons Bandit has moved to using Compu-Fire electrical components on most of his bikes. First, because even he can install them, and most of all, because Compu-Fire has been building electrical components for years. The stuff doesn’t break.
Take, for instance, this charging system. The stator slips firmly in place over the engine sprocket shaft race area and Compu-Fire suggests that you use the stock fasteners with a drop of red Loctite to ensure it won’t ever come loose. Compu-Fire alternator plugs are the protruding variety from the late-model design. Carefully oil the plug and slip it into place, then replace the plastic bridge and fasten it with blue Loctite. If you have new cases, make sure there are no sharp edges on the plug opening. File if necessary. Then with the shaft seal .090 shim in place, use a wire feeler gauge to determine that you have at least .060 of clearance between the rotor and the case.
With each Compu-Fire charging kit for Shovelheads or Evolutions comes a thrust washer that goes on the outside of the rotor on chain primary systems. It may not be necessary on belt drive primaries. Mr. Gillihand from Compu-Fire recommends that you have a direct ground to the engine cases. Compu-Fire charging systems are the series type, unlike the shunt variety. The difference is that a shunt type drives the charge to ground if the battery is satisfied, causing the alternator to heat up and constantly work. The series type shuts the stator off when the battery is satisfied, which allows the unit to cool. The hot wire goes directly to the battery through a circuit breaker, or to your ignition switch on the hot side. In this case, the regulator was positioned with the coil between the tanks so the plug wire had to be extended.
That covers the basics of installation. Now here are the specs: Compu-Fire manufactures two versions of its charging kit, a 32 and 40 amp. From 1970-’75, stock charging systems were rated to 15 amps; from 1976-’80, they were 17.8 amps; between 1981 and 1988, they jumped to 22 amps; and finally, in 1989, skyrocketed to 32 amps. Now fuel injected models run 38-amp systems. So the two systems cover the lot.
We’ll get into wiring after paint and chrome. The ignition system is Power Arc. The timing module is in the nose cone and the coil is also positioned under the seat with a chunk of angle iron. This system is about as clean as you can find.
Next week we’ll hit the final sheet metal as we close in on paint and chrome, and the lovely Princess Lena, daughter of the rich and powerful Rick Fairless, king of the Strokers Ice House plantation, makes her move on the hapless Bandit. –Wrench
5-Ball Factory Racer Tuning issues
By Robin Technologies |
This has been the strangest tuning dilemma I’ve ever faced with a motorcycle in my 40 years of messing with these bastards. I fell in love with our Factory Racer CrazyHorse 100-inch engine. The day we started the bike for the first time, it fired to life immediately, no hiccups, stumbles, or coughs. Every time I hit the Phil’s Speed Shop electronic system starter button, it immediately rumbled to life. Then we attempted a break-in ride and it blubbered badly at mid-range. If I nailed it, it jumped forward, then stumbled and nearly died. I was perplexed.
At first we thought, and so did S&S, that our Crime Scene air cleaner, facing backwards, was the evil culprit. We began an extensive investigation. Larry Petri, the master Chop N Grind mechanic, came over and we tried some jetting changes, which didn’t seem to help. We went to Bonneville, so we shifted gears to our Peashooter project until we returned.
While cleaning the shop after Bonneville, I came across another S&S Super E, and installed it immediately. The bike did the same thing, so we ruled out the carb for a minute, and I investigated whether there was any chance it could be the ignition.
According to a few CrazyHorse experts, the Thunderheart ignition system could have been the problem, so I reached out to Thunderheart in Florida. They asked me to send them the ignition module and the cam sensor, which I did. They told me the cam sensor was defective and replaced it. I re-installed it and the bike did the same thing, blubbered at mid-range. I performed another Thunderheart test by running a power lead from the battery directly to the coil. No change. I tried the power lead to the other coil connection, and believe I blew out the ignition. It wouldn’t start again.
After speaking with several builders, I was convinced the problem was the Thunderheart. Frank at Black Hawk Motorworks builds a billet bottlecap cone, allowing us to install any Evo ignition to a CrazyHorse, so I headed in that direction. Frank recommended a mid-range S&S cam, which would require new adjustable pushrods, also from S&S. Ultimately, I ordered the S&S Quickee pushrods, so I didn’t need to remove the rockers for installation. Life was looking up. I also ordered a single-fire ignition from Compu-Fire, one of the easiest ignitions to install on the planet.
That’s the complicated direction we’re headed today, the S&S cam installation, the S&S pushrods, the Compu-Fire system install, and the whole unit detailed by Heather New, of New Line engraving.
First, I pulled the Thunderheart ignition, which I grounded to the bottom of the transmission, and we pulled the ignition cam sensor off the front of the engine.
Next, we pulled the pushrod caps and clipped off the pushrods with an old set of shop bolt cutters. The cutters were so old, I had to disassemble the cutters, grind the jaws, learn how to adjust the jaw alignment, and re-assemble the cutters. They worked fine. The S&S instructions always call for disconnecting the battery, which is a damn good idea. It’s always a good idea to run the engine to top dead center (TDC) before clipping the pushrods, so there’s a minimum of pressure on the rods and parts aren’t jettisoned around the shop.
With the stock non-adjustable pushrods out of the way, we could remove the cam, which was also an S&S unit 35-0157. We were going to replace it with an S&S 561V , part number #33-5076 configuration, which was recommended by Frank Aliano of BlackHawk Motorworks in Florida. He has studied and built products for the bottlecap Indian engines for years.
I removed the cam plate fasteners and carefully removed the plates. The BlackHawk Cone came with replacement gaskets and O-rings, but I was careful not to damage anything. The stock S&S cam slipped right out of place, along with the thrust washers. I dug around for more replacement thrust washers for setting up the proper cam clearance.
You need to read the S&S cam installation instructions closely. Depending on the year, the cam lobe height, the model, engine size, etc., you may need to follow different portions of the directions. For instance, S&S recommends that you replace the cam bearings in 1992 and later big twin engines with a Torrington bearing, which has a higher radial load rating and can handle the performance stress.
I replaced the cam several times and checked the clearance with various thrust washers. S&S calls for an endplay measurement of .005-.015. This CrazyHorse 100-inch monster has the new oil pump mounted to the front of the motor, so there was no breather gear alignment issue. I thought it was a breeze and aligned the cam dot with the pinion bearing. There was also a red paint mark on the pinion gear about two teeth from the alignment dot. The red mark was there for gear size when the engine was originally built, not alignment.
But after I bolted up the cam plate, I questioned my alignment and removed the plate again. The cam had two marks on it. One was for a breather and the other for the pinion gear. I needed to make sure I was using the proper indicator for pinion gear alignment.
I ducked through this process several times. Another stumbling block surfaced: the lifters didn’t stay securely in the lifter stools. In the old days, solid lifters stuck well above the stools, so they could be held by hand or with a rubberband while the cam and thrust washers were replaced. I monkeyed with this, even removed the rear lifter stool so I could check the endplay and push two lifters out of the way. Ultimately, a sharpened piece of welding rod, bent just so, helped with the process of holding the cam followers in line.
I bolted up the new cam chest plate, with new O-rings. I made sure to oil the cam bearing surfaces. I had a set of standard S&S adjustable pushrods, which require removing the rocker arm assemblies in an Evo configuration and dropping in the pushrods from the top. I anticipated a problem with this endeavor and ordered a set of S&S Quickee Pushrods for this application. I didn’t want to mess with the engine to create the clearance to remove the rear rocker box.
Again, when I received the instructions, they were broken down for virtually every model available, from Buells to Panheads. I went with the 1984-1999 Big Twin instructions, which call for rotating the engine until the front piston is as top of its stroke, with both front lifters at their lowest position (TDCC–top dead center, compression stroke). If you look in the timing hole of the Crazy Horse engine, a black dot indent emerges at TDCC, so it was a breeze to find. I cleaned the pushrod tubes and replace the O-rings with a light coat of oil, inserted the new pushrods through the tube assemblies, and installed each one in the proper position.
I extended the adjusting screw to remove all the lash in the pushrod, then compressed the hydraulic unit in the exhaust lifter four complete turns or 24 flats, then tightened the lock nut (Frank recommended 4.25 turns). Then you are required to wait 5 to 10 minutes before adjusting the intake pushrod, so the valves don’t run into each other. After the waiting period, the pushrods should turn with fingertips.
I repeated the above procedure for the rear cylinder, and then replaced the cover clips and spark plugs. The instructions called to starting the motorcycle and checking for leaks. That’s good info. I blew oil all over the place before I discovered a pushrod cover that hadn’t seated properly.
Here are a couple of helpful warnings. First, if you are unsure about the lifters, here’s a way to check it. If you adjust the pushrod down four turns and wait, then try to turn it with your fingertips, and it doesn’t turn, you have hydro-solids.
Next, S&S Quickee pushrods for all big twin engines contain two long and two short pushrods (exhaust-long, intake-short). All Sportster models and Twin Cam 88 pushrods are the same length.
Now I could install the Compu-Fire ignition system. I left the engine in the TDC position for this maneuver. Compu-Fire has several systems, including single fire, dual-fire, and kick-start units. You can remove your point system and drop in one of these puppies in a flash. The system is a breeze to tune and it’s and all-in-one unit in the cone.
I’ve known the boss of Compu-Fire, Martin Tesh, for a couple of decades. He knows his shit when it comes to these simple, easy-to-tune, solid-state units. The unit comes with complete instructions, but basically, you replace the cam plate, install the ignition plate in the cone with a drop of Loctite, and run the wiring harness to the coil. Install three wires, tune the bastard with the supplied magnets, and you’re good to go. It even has switch settings to allow you to adjust the timing curve at 35 degrees before top dead center at 1500 rpm, to 35 degrees at 3500 or 4,000 rpm, depending on the model. You flick a switch, test ride it, and it’s set.
Here are the official Compu-Fire ignition installation requirements. First, I cleaned out the pristine Black Hawk timing cavity. I didn’t need to worry about the seal, it was brand-new. I installed the trigger with the long supplied Allen screw, and checked the gap between the trigger and the ignition plate. It seemed excessive, so I checked it again, and installed the supplied shim to tighten the gap. I aligned the trigger with the notch and torqued the Allen screw to 25 inch-pounds. The large round TDC indicator ding in the flywheel was still centered in the timing hole, so I was good to go for timing.
Just to be sure, the locating cam notch falls in the same place for every big twin cam, if the TDC mark is on the compression stroke. It always comes up at 7:00, so I checked it and was good to go. If it wasn’t, I needed to run the engine over one more time to be on the correct compression stroke. It was time to set the timing.
The directions called for turning the ignition switch off and reconnecting the ground wire to the battery. The instructions called for stripping the Compu-Fire red wire and temporarily connecting it to the battery positive terminal. I rotated the timing plate counterclockwise to the full retarded position. The Accu-Ray timing light may be on or off when you start this procedure. I used the disc magnets to turn it off and on by swiping them across the timing plate. It’s like magic. I turned the light off, then rotated the plate clockwise until it popped back on. I did this several times until I could lock the plate in the exact spot where the light came on.
Frank, at Black Hawk suggested that I rotate the plate a hair past the light-on spot to advance the timing slightly. Then I locked the plate down and I was done. Except to install the new Heather New engraved timing plate cover.
I disconnected the hot lead, and then wired the Compu-Fire ignition system in place according to the single-fire wiring diagram with a new Compu-fire single-unit, single-fire coil.
Okay, so I fired the beast up and went for a ride. Same problem. It blubbered at mid-range. It had to be a carburetor issue, so I yanked the S&S and installed a Mikuni 42-mm slide carb. I pulled it out onto the street, fired it up, adjusted the mid range air nozzle and the idle screw, and slammed the tank shifter into first. She popped but ran like a top.
That did it. It had to be a jetting issue, but then an uncustomary California storm rolled in, and it rained solid for a week. Hell, it’s rained for six weeks in Brisbane, Australia. And we thought we had flooding issues. I’ve been working with Paul Cavallo and his teams at Spitfire on our 2011 bike build efforts. I’ve had the privilege to speak often to his main builder, Larry Scrotum, a guy who has been building bikes for as long as I’ve been writing about them. Just recently, during a break in the weather, I mentioned my problem to him, and he was the first to come up with real solutions.
It could still be the Crime scene air cleaner and the way it’s positioned, leaving the choke vent open. He says the air rushing over it causes a problem with the fuel delivery inside. I needed to block off the outside vent and take the Allen screw out of the underside of the body adjacent to the vent. I’ll let you know what happens next. He also made a tuning suggestion regarding the air bleed vent in the float bowel. I’ll let you know the outcome.

Sturgis Shovel Part 5
By Robin Technologies |
Helluva weekend. Anytime there's lots of motorcycle carnage,sex, whiskey and writing, I'm all for it. Maybe it's Valentines Daycreeping up. Make a note. Here's the deal on the Sturgis Shovelhead. Sincethe engine was in and mounted I went to work on the exhaust system,then seat mounting, position and played with the bars. I made a runto a local steel joint, because I had a notion that I doubt will worknow, but I'm still investigatin'.
Let's hit the highlights. I'm fortunate to have a young,talented fabricator/builder who I'm sharing ideas and resources with.Kent from Lucky Devil Metal Works in Houston is on the phone dailyfor tips and knowledge sharing. It's damn healthy to have someone whois in the trenches daily to assist. In fact I had a couple ofcrucial metallurgy question that morning, but let's hit what Iaccomplished.
A crucial aspect of building any bike is planning. That'snot to say all my eggs are in a row. We'll see, but the more you canaccommodate, the less redo's will be necessary. Also, don't throwanything away. That junk part might be a critical bracket tomorrow. Idug through my partially organized pipe bin and found a set of oldglass pack, shorty muffler, shot gun pipes. I could use the rear one.I decided, since noise issues are a concern and performance issue area constant priority, I would build a set of shorty mufflers withBandit tuned baffles.
Then I spotted the fishtips in the pile and myconsideration changed. I dug further. Kenny Price from Samson allowedme to dig through his warranty bin when I was looking for stanchionsfor my Bikernet office railing. I remembered touring mufflers withfish tips, I kept digging.
Sure enough I had a set and in quick movesI sliced them into chunks. You know me, I'm a gambler. I cut themwith no methodology in mind past the size and looks, but I came uplucky. Samson designed a baffle system with a cone at the front toguide exhaust pulses into the baffle and it seems to be working fortouring applications. I cut off that portion and discarded themajority of the baffle. But there was still 2 inches of baffle and astandard donut in the rear of the muffler. That's where fate movedit's evil hand over Richard Kimball again. Or in other words I rolledthe dice.
I spoke to Kendall Johnson recently and he told me aboutperformance stepped exhaust systems and reversion cones used to tunesystems at the rear of the pipe. I couldn't make this donut move upand back, but I had the makings of a reversion cone at the stern.With a torch I cut out the remaining baffle, then after speaking withthe HOT BIKE staff member, Craig Murrow, for a reversion cone descriptionI knockout out the remaining baffle, then with various cutting andgrinding cones I formed and smooth departure for the exhaust pulses.Then I had to remove the old touring mounts with a die-grinder andthey were ready to weld.
The rear pipe was comparatively easy since the pipe wasalready made except for the muffler and brackets. Shovelheads arenotorious for louse exhaust manifold connections and tearing out thesingle stud, so I wanted to mount them in the front and rear for asolid, secure connection. The only port for the connection at thefront was the oil bag. That was a bad choice and I'll run a bracket off the seat post before all is said and etched in stone.
I had to make sure the pipe could be removed with the tabs onthe bottom, then I spaced the tabs apart with a heat sink material. Imay use Teflon, then the notion that the oil bag is rubbermountedfloated to the surface. What bearing would that have on thiscoupling? Hell the frame will vibrate like a mad dog. I'm stillquestioning that link, but we'll see, maybe a spring between the tabs? The final decision was the seat post bracket to come.
There was one other pipe design consideration–the length.I try to keep the pipes somewhat equal and between 32 and 38 inches.Buster's Sportster runs sharp and crisp with his hand-made 38-inchesfrom the Bikernet Headquarters, as seen in Street Chopper. So Idesigned this pipe to be 38-inches and not protrude past the tire. Mygoal was to make the front pipe curve out the other side and be ofequal length.
At the end of Friday night, one pipe was complete, toolswere scattered all over the shop and I had a couple of Hooker Headerchunks of 1 3/4 pipes segments cut and was fooling with the frontheader. The front was tricky as hell. I wanted to scoop out the leftside of the bike, which added length. I also had a bitchin Rohm Engineering oil filter/cooler system that mounts to the front motormounts and aims the filter at the ground for ease of removal anddraining. The pipe had to clear it significantly. This puppy was alifesaver. I planned to run an oil cooler (Shovelheads run hot) andfilter, for a lasting driveline and more oil capacity. My originalplan called for old school mounting on either side of the oil bag.This eliminated all of that and the plumbing for two elements, the cooler and the filter, wasreduced to one hot looking job in front of the engine for maximum cooling.
I spentall day long on Saturday, dodging the phone and working in thegarage. I had all the tools and materials I needed, even two new setsof welding glasses, which came in damn handy. The trick was to lineup the pipes, make all the right decisions, hope for the best andtack 'em. I did and with a level I constantly compared the pipe tothe top of the lift. The spacing worked out fine.
I cleared the top of the Rohm bitchin' oil cooler/filter mounthopefully by enough to allow the pipe slip down and out of the head (I was recommended to use a CCI Filter part number 270126).I tacked the tab with a spacer between the two for some jiggle room.And I made damn sure that the pipe tab was below the frame tab. Atthe back, the muffler was fabricated the same as the other one with aslight exception.
I shaped the reversion cone the same, cut off thetouring mounts and ground the tabs. Then I used a couple of V-blocksto hold it perfectly in line for tacking the halves together. Then Isliced off the crush tabs on the front of the Samson tapered muffler.They were wider and different than the other side, so I cut them off.You'll notice the difference, if you check both side.
The front parts of the pipe were Hooter elements and theyare smooth mandrel bent segments. I used another one for joggedstraight piece between the muffler and the head. I took the 13/4-inch exhaust to my Muffler Master bender and bent it slightly oneway, then reversed the sucka and bent it the other way. It fit like adream and looped out enough to pass the oil bag. I used Hooker headeralignment sleeves to hold the front pieces in perfect alignment. Donedeal, I tacked them, constantly comparing the level with the lift,the pipes then the muffler. After the tacking was secure, another tabwelded to the frame, avoiding the oil bag (a Lucky Devil concern,since the oil bag is rubbermounted), then all elements wererechecked, I removed both pipes and MIG welded them as complete aspossible.
I find that MIG welding is a pain and blows holes in pipes easily.I also discovered that after I MIG weld a pipe I can flow the weldeasily with a torch and smooth out all the welds, fix holes and fillgaps. I actually found a piece of old steel rod, not much bigger thana piece of wire. I usually use old coat hanger, but it pops andwheezes from the paint coating.
After the pipes were welded, flowedand checked twice, I ground all the surfaces with an emery disc andpainted them with whatever barbecue heat paint I had laying around.The lovely Layla is currently on her way back from Home Depot withsome flat black heat paint. We'll see how that works.
Kent from Devil hand fabricated the seat pan, brackets andbungs. I set them up and welded the parts in place. Then it was timeto roll the bike off the lift and see how she fit and where I mightneed heat shields. I discovered a couple of things. Yes, the scootwould require left side heat shields and nothing on the right. I alsotested my notion to sculpt claws out of brass, unsuccessfully.
I also found that the existing bars wouldn't cut it. Igrabbed the old '48 Panhead TT-bars, narrowed them by 4 inches, and Isorta like them.
Okay, so I grappled with the sculpting business fora couple of hours and discovered that I can't control the brass likeI can steel. I spoke to Kent from Lucky Devil and he recommended thatI try TIG Silicon Bronze rod. I'll try that next week. In themeantime, my first brass sculpting attempt ended up on the shop door.Let's get the hell out of here.

Sturgis Shovel Part 1
By Robin Technologies |
We're starting another project at Bikernet, the Ultimate Chopper. I dediced that title was bullshit. I look at some of the bikes built nowaday and mine pale by comparison, so screw it. It's the Bandit/Sturgis 2005 Chop. It's been a couple of years since I built a bike for myself. Hell, I can't ride the shrunken FXR, it's too small. Besides I need a rigid chopper for everyday flying. I gotta tell ya, I love choppers, like women. They're sleek, slim and move with an indescribable grace.
Here's the design notion. No we're not trying to compete with the Martin Brothers, Paul Yaffee or Matt Hotch, who are all master craftsmen and artisans in the custom motorcycle world. They are incredible and I have the utmost respect for each one of them. I'm sorta Indian Larry West. I want to build a light agile chopper for the ride. I'll attempt to explain. I've been riding choppers most of my life. I've tried out many styles, but consistently come back to the mighty light weight chopper.
Let's get specific. I needed something stretched to fit my 6-foot, 5-inch frame so were going with a stretched Paughco Rigid with 4 inches in the downtubes and 3 in the backbone. But I'm sticking with a very moderate rake of 35 degrees for handling. I'm running a 9-over light tapered leg Paughco springer for class and city handling. I'll run my traditional Custom Cycle Engineering risers for limited handlebar vibration and traditional appearance.
One of the notions is to make this bike a very reliable, rideable chopper for long hauls, maybe to Sturgis next year. I would generally run a 96-inch Evo to fit the rule, but this time a brother, Richard Kransler cut me a deal on a Shovelhead engine with 3 5/8 bore and 5-inch stroke. That over 100-inch monster would tear this bike apart in short order so I called S&S for advice.
We're going to roll with a tried and true S&S formula for street power, reliability and balance–same bore with 4.5-inch stroke will give me 93 inches of grunt. I tore the engine down for modifications last week and shipped the lower end to Viola, Wisconsin for a S&S blessing.
In keeping with the chopper code of the west, no fat assed tire will cramp the handling. I'm going with only an Avon 180/18 and a 21 on the front. No wild billet wheels but clean Custom Chrome polished aluminum rims and 40 stainless steel spokes. This bike will have a touch of chrome, but not much. I'm going to start a bin of Stainless Allen fasteners to take care of assembly.
I'm not going to run anything that sticks out from this bike, no sidemounted license plate bracket or wide bars, just tall risers and what I call TT bars that I will narrow for splitting lanes on LA freeways.
I may use a flush mount Sporty tank, or perhaps a Cyril Huze job like the one on the Shrunken FXR. What a sharp tank. I'll use a BDL belt, Compu-Fire alternator/ regulator and single fire ignition for reliability. We're mounting Kraft Tech fenders and oil tank, making our own pipes and brackets. Dewey's custom pegs will be used because they're light and contain just enough rubber to keep vibration away from feet and hands. The foot and hand controls are all Joker Machine for true reliability and simple clean design.
The Jim's 6-speed overdrive tranny is waiting a Custom Chrome Sprocket and Rev Tech O-ring chain. Finally I'll research the best possible sprung seat for comfortable, vibration free ride.
We're shooting for a bike that will be solid for the long run. It'll run strong, won't vibrate to shit, be reliable enough to ride to Sturgis, a street fighter in the old school fashion. Not a lot of flash, but tremendous class. Watch as it comes together right hear on Bikernet. Oh, I've got a couple of tricks up my sleeve that will be revealed as we turn this pile of parts into a running gargoyle.
1928 Shovelhead Project Part III
By Robin Technologies |
The lovely Lena Fairless, who has threatened to marry Bandit (the sixth Mrs. Ball) and make him work for her folks at the Easyriders Dallas store, has been pushing to see that this 1928 Shovelhead project is completed in time for her wedding plans. Bandit doesn’t seem to move unless there’s a motorcycle and a woman involved. There’s just one problem in this case, which Lena is well aware of, she’s under age…
The other news on this project is that we now have a corporate sponsor, Ed Martin of Chrome Specialties, and a mentor, Chica, who builds bikes in Newport Beach, Calif. Chica built “Trick,” the old-time Sportster that Chrome Specialties is displaying at all the events it attends, such as Laughlin this month. Randy Simpson from Milwaukee Iron and Arlen Ness are also building spindly retro scoots with late-model drivelines. I spoke to Arlen the other day and he told me that a number of top builders in the country are building this style of beast for upcoming shows. Arlen is now building Sportster frames, sidecar frames and the tubs for these units. He’s sold 10 sets. Don Hotop is building aluminum tanks, so soon the parts for building these retro bikes will be even more available.
The contact stateside for the European parts we used is Fred Lange at (805) 937-4972. He has access to seats, fenders, front ends, tanks, headlights and more. Let’s see if we can pick up where we left off.
The frame is a stock rigid Panhead configuration from Paughco, with a stock, late-model Bad Boy front end. To drop the front slightly, Jim Stultz, Rick’s main fabricator/bike builder, used a KT components lowering kit to make the frame level because the newer springers are XA length. The retro tanks are sweat-brazed together and contain the oil in one half and the gas in the other. Unfortunately, the tanks did not fit the frame at all and had to be disassembled, cut and re-welded to fit. The fun part of such a round-the-town project is that it can be a true swap meet special once you have the basics in hand, and you can slip as far back into the retro world as you want. You can roll with chain or belt. You can use any old brakes you have around. Rick chose to use disc brakes and a chain, but he’s going with a jockey shift and internal throttle assembly from Chrome Specialties. The charging system will be state-of-the-art Compu-fire and the carburetor S&S. The engine and transmission were rebuilt from the ground up by JIMS machine and the engine cases are STD.
Both wheels are 21s for that spindly look. The handlebars were designed by Jim and bent by Milwaukee Iron. With the internal throttle cables, there will be a minimum of controls on the handlebars. Since the transmission was rebuilt with the notion that it would be electric start, an aluminum inner primary will be used with an old-time-looking tin outer primary that Rick picked up at a swap meet. Rick ordered a narrow Karata belt drive for the primary.
Jim sliced all the mounts off the frame except the front footpeg mounts, the engine and tranny mounts. Since the oil tank is part of the gas tanks, the only additional container would be for a battery to conceal a car-type marine ignition switch and a light/toggle switch.
“I try to fabricate components to be user friendly,” Jim said. He designed the battery box so it would only take two bolts out of the seat post and two out of the rear section and the whole pan will lift out through the top. The two sides covering the battery will meet in the middle in a flying wedge configuration, and Jim plans to build a top cap to conceal the battery from the area under the seat.
The steel gas tanks, once cleansed of the brass, were chopped and channeled to clear the rear head. The entire center of the tanks was removed to fit over the frame. Unfortunately that reduced the gas capacity to 1.5 gallons. The European threads in the cap bungs were tapped out of sync, so they had to be re-machined.
Lena teases Bandit with occasional shots from her mother’s digital camera. Next week we’ll discuss the mounting and installation of the Compu-fire ignition. Some members of the staff will be happy to see Bandit go to Texas, others, mostly the women, are bummed. He even called to see if he could ride it back to the coast and was told that it didn’t carry enough gas to get him out of town. Evidently the tank is Lena’s design.

Mudflap Girl Part 1, the Concept
By Robin Technologies |
Life is nuts, or is it just me? Fortunately, we have motorcycles and women to chase. And this year became the year of the Evo, the FXR, and the mudflap girl. I’m scratching the back of my head and wondering how to kick off this build for 2011. There’s a lot on the plate this year and it’s a tad difficult to explain. First, I must fess up. I’m turning 63 this year and no more riding rigids to Sturgis, or even chasing young broads. Ah, but the adventure continues. It’s actually a blessing not to be hassled with women troubles. I’ll let my son, who just turned 37, deal with the addiction to soft curves. I’ll hide out and watch…
The solution for my missing long distance rider was an FXR, and I have one, the John Reed V-Bike that I took to Bonneville in 2006 and set a 141-mph record with a top speed over 150. Unfortunately, I have a hip problem and can’t ride mid-control bikes anymore. I even modified that puppy, but that didn’t do the trick. I love that bike. So, what the fuck was I going to do?
Okay, so I started to piece this bike together. We factory re-manufactured a ’98 Evo engine and JIMS rebuilt the transmission into a six-speed. I had a couple of Renegade Wheels and Progressive Suspension shocks. Then I had a conversation with Kenny Boyce, the man who designed the Pro-street FXR frame. He wasn’t happy with now-defunct Quantum. I also found out that some of these frames break in front of the seat area at the backbone. The project was moving forward with a Custom Chrome, super-wide, upside down front end, Aeromach risers, and we added super wide, Burly bar highbars.
I even had an aluminum mudflap girl oil tank I ordered from Nick at New York Choppers. The bike was leaning toward a pro street touring model with a set of Redneck Softail fiberglass saddlebags and a Klockwerks touring bike rear fender.
I was rolling when Kim Hottinger called and asked if I could haul my old ass out to the American Built/Spitfire manufacturing facility in Rancho Cucamonga, California. Paul Cavallo was the engineer/manufacturing guru behind Hellbound steel. As we watched the production chopper industry dry up, in the wake of a floundering economy, only the diehard survived, and I wanted to support anyone who understood the code of the west.
The brothers who love motorcycles, choppers, bobbers, and custom parts continued to jump up every morning and do what they adore, work on motorcycles. Some went from building hundreds of bikes every month to a handful, but they kept building. Paul downsized and kept rolling with his father at his side. When I saw what he was up to, I was inspired. He can build any frame, for any motorcycle configuration, so my mind went wild. We could build a Frisco’d and stretched, single-loop FXR, and I dragged an old Durfee girder out to his facility so Paul could see how the master built the originals. Imagine an FXR with a state-of-the-art girder.
Paul is a wild man when it comes to building and manufacturing anything. He re-engineered the girder and refined the looks, and added two shock mounts to incorporate a state-of-the-art front suspension. Over the next year, you’re going to witness Paul’s Spitfire abilities with features in several national magazines, and you’ll begin to see his products pop up in Custom Chrome catalogs.
The more we moved forward with this bike, the more inspired I became. This was a bike for me, maybe the bike for my old-guy riding future, now that my Road King was down the road. So I went to Paul with the deal of the century: build two of these frames and front ends. I spoke to Paul, then to my son.
There had to be a goal behind this effort. We would ride to Sturgis together. Shit started to happen fast and I ran into a TV producer who wanted to follow the build, and Leomark studios got involved.
Next, I reached out to Chris Kallas and we started to work up a concept drawing. Here’s some of the e-mail that flew back and forth.
Here’s my initial description:
Frank’s bike: classic black mag wheels from Metalsport. Klock Werks rear dresser fender on Frank’s, might bob it. Both wheels will be mild width. Mudflap girl theme on my bike and Hardball tattoo on Frank’s. Paint reversed from Frank’s bike to mine. Forward controls on my ride, Frank’s will run mid controls. Rubber pegs, grips. dog bone-style tall rubber mount risers. Shotgun pipes. One Redneck bag on the left of Frank’s bike. We also talked about a small front fender.
–Bandit
Some questions?
Black and chrome or silver Evo engine?
Your wheels? Mag or spokes, what kind?
Style/brand of headlight, tail light?
The risers are the type with rubber mount at top?
Carb/aircleaner?
Shot gun pipes, staight, no mufflers?
Style of seat?
Your fender the same not bobbed?
Brakes? Dual or single up front? What brand of rotor/caliper?
If any of these things aren’t specific yet, they could be semi generic on art.
If you can send any photos or links to of fenders, wheels, bags, brakes or controls, it would be helpful.
As for paint, just a thought.
It looks good with lots of black or aluminum, and chrome.
It also looks good with your signature orange accents or striping. Since I’m not crazy for white frames, they could both have blue frames and just flop the two-tone paint on the tanks and fenders.
— CK
Here’s the basic FXR platform showing the frame modifications.
This is with a 3″ extended swing arm.
I need to go back and recheck some measurements but it will give you a
rough idea of the stretch up front.
Is this the type of exhaust setup you were thinking of?
When you said shotgun and 2-into-1, I wasn’t sure.
— Chris K.
I think we should go with this type of exhaust, if we plan to pack passengers. I’m going to ask Dar about that swingarm, but my tendency is to extend it about 1.5 inches, not 3. The stretch looks great. Let’s fuck with those fender rails, arch them, or make them disappear and bob the fender slightly. Plus I think we will need to lower the rear at least an inch, with shorter shocks.
–Bandit
Hey, here’s my first crack at putting it all together. Overall the stance looks good. Since it’s a rough draft without much decoration, I just threw a couple
of mud flap girls on it. I thought I’d try a traditional Sportster/FX headlight with it’s rubber- mounted bulb to stay with the theme of using rubber pegs, grips, and
rubber mounted-risers…. not to mention a rubber-mounted engine, plus I like them.
The frame tube behind the shocks creates a challenge for curved fender struts. I’ve included a couple of photos of some frames so you can check out that area, plus for general interest I tried mounting the tank higher (Frisco style) but thought this looked better.
You might use a semi-later model Sporty tank (when they first started making them larger but still had a carb).
I don’t know at what angle or how Spitfire plans to deal with the secondary neck brace under the tank, so just drew it how I thought it might go.
When you said a Fantasy in Iron tear drop air cleaner I took that to mean a plain Goodson (no rib), for engraving. (We now have a Roger Goldammer air cleaner for Frank’s bike)
Since you need to run a front fender, I made it small. I like when they show most of the top of the tire.
Questions:
Who’s handlebar and foot controls do you plan on using?
How about brake calipers?
–CK
Hey, Chris,
I feel like I want more attitude. How about the tank mounted in line with the bottom of the top bar and stretched a tad at the back to more of a point? Take out the stress bar and add a gusset there with a mudflap girl cut out.
Check the news. I ran a shot of the air cleaner, but you nailed it. Did you check out the heavy green flake and silver bike? I like that theme. My bike will have a plain engine. I thought that style worked well with the plain silver, driveline. And I liked the green springer to match the frame.
We don’t need to go with green. It could be almost anything and silver, then reversed for Franks, with a silver frame, and colored sheet metal.
–Bandit
If the Redneck bags wouldn’t fit, we looked at what Bob T. runs on his fantastic RT.
Part number for bags:
’87-90 FXRS conv bags
H-D 90702-89 left
90703-89
As you can see we are flying at this effort. Don’t miss the frame build in the next segment. As it turns out Frank and I will be running the same drivelines: JIMS six-speed transmissions and Harley-Davidson Evo engines.

Mudflap Girl Part 2, the Bandit Engine and Spitfire update
By Robin Technologies |
Okay, you have the story behind this build, and Chris Kallas is refining the concept drawing. My engine arrived from the factory, and Eric Bennett immediately noticed the return address, in Viola, Wisconsin.
As it turns out, the factory hired the S&S crew to assemble their Evo line of engines. What a natural. I liked that notion all the way around the block. First, it means more American hands in my new engine. Plus, what could be better than to have the best performance engine company on the planet working with the factory on the last and most refined V-twin configuration?
For this crew, and lots of riders all over the world, the FXR Evo is the best of the best. So, for Bikernet, this became the year of the FXR and the Evo engine. I asked the factory about their Evo engine program and received the following information.
A Modicum of Harley Engine History
The first 74 cubic-inch V-Twin engine on the JD and FD models was introduced in 1921 and the 45 cubic-inch side-valve V-twin engine (later to be known as the Flathead) on the D model debuted in 1929. The Flathead engine proved so reliable that variations of it were available on Harley-Davidson motorcycles as late as 1973 (servi-car trikes).
In 1936, Harley-Davidson introduced the EL model with an overhead valve, 61-cubic-inch engine. With increased horsepower and bold styling changes, the motorcycle earned the Knucklehead nickname, due to the shape of its rocker boxes.
New features were added to the 61 and 74 overhead valve engines in 1948, including aluminum heads and hydraulic valve lifters. New one-piece, chrome-plated rocker box covers shaped like cake pans earned this engine the nickname Panhead. The engine introduced on the Electra Glide models in 1966 to replace the Panhead became known as the Shovelhead, again due to the shape of its rocker covers.

When my engine arrived, I immediately hauled it in the Bikernet Hearse to Bennett’s Performance for a slight performance upgrade. I needed to let that puppy breath without messing with the reliability aspect. Sharing the same building on the edge of Signal Hill, California is the headquarters for Branch O’Keefe. John O’Keefe worked for Jerry Branch for decades and ultimately bought the business when Jerry Branch decided to retire.
We’re looking at several options for stock engines and for rebuilds. We have three touring models coming together right now, and they are all 80-inchers. One for my son, my factory motor, and Dr. Hamsters 200,000-mile Evo rebuild by Bennett’s.
I’m running the brand-new factory plain Evo engine with the Andrews EV-27 cam and Andrews chrome-moly adjustable pushrods for less flex, a new cam bearing and the Branch flowed stock heads, for 8.9:1 compression, 78 cc Branch-flowed chambers, and 75-80 horses at 2,600 rpms.
The next higher upgrade step from Branch is the EV-51 cam and additional headwork and shaved heads for a 10:1 compression and 85 horses at the same rpms. And finally, a customer can run with an EV-59 Andrews cam and 10.5:1 compression and 90-95 horses. Not bad for never taking the barrels off.
“I like rpms,” John O’Keefe said, “and the new ignitions allow these engines to burn more fuel and bring out the horses.”
The key to all this performance is the headwork set to match the cam, and John O’Keefe has studied this science for most of his life. The key is building a mid-range hot rod without sacrificing reliability.
The first move was to strip the engine and deliver my fresh factory heads to the Branch team. Eric Bennett set my beautiful, plain H-D Evo engine on his clean room bench and removed the top motormount, the top rocker box that came off with the middle ring. We noticed much improved, one-piece factory Teflon gaskets. We won’t mess with them. Then Eric removed the rockers, the pushrods, pushrod tubes and rocker boxes. We also retrieved the new base gaskets to reuse.
Then he removed the head bolts, the front head, and the rear head. I had already purchased the Andrews EV-27 cam from Branch O’Keefe, and Eric and I started to prepare for installation. He removed the point cover, ignition, and cam sensor.
He had a terrific Trock tool for removing the cone cover. It’s always a bastard to try to carve around the narrow gasket surface with a screwdriver or a knife, hoping to find opening and risk damage to the cases or create a leak by scratching the gasket surface.
“We always replace the new factory cam bearing,” Eric said, “with a full compliment Torrington bearing. The factory ran the good ones from ’55 to ’92, then they shifted to a cheapo brand. It’s also not a bad idea to replace the factory plastic breather gear with a solid JIMS unit.”
I scrambled to take notes and photographs while Eric peeled into my engine. He popped a factory set of magnetic tools into the lifter stools to hold the lifters up during cam removal. I wish I had a set of those puppies.
“It’s interesting,” Eric said. “Virtually every stock cam is .060 longer than any aftermarket cam.”
Eric pre-measures the cams and adjusts the thrust washers before replacing the cam, which you will see in the next report, when we study the Branch recipe for performance, the headwork, and modifications. He replaces the valve seats for larger valves, then ports and polished the chambers. You won’t believe the long-lasting components Branch uses.
Then we will watch Eric replace the stock cam with the Andrews unit and adjustable pushrods, and put the whole Evo puppy back together. “Don’t forget to order a top end gasket set,” Eric reminded me as the rain cut loose outside and I wondered if this winter season would ever end. I need a ride.
Then Eric grabbed a JIMS tool and a couple of wrenches and in 30 seconds pulled the cheap cam bearing from the new cases.
“I’ve seen these go south in 10,000 miles,” Eric said. “I’ll never understand why they replaced a perfectly good quality bearing with this junk.”
Just as quickly Eric took an aluminum guide and a mallet and tapped the new bearing in place, another 10 seconds passed, and we were finished.
A couple of days passed and I thought, just maybe my frames and front ends would be completed at Spitfire. On a hunch, I peeled 57 miles away from the coast in the hearse while listening to KJazz on the radio.
It was quiet as I wandered into the vast machine shop, welding shop, bike assembly area and ran into Joe Cavallo, Paul’s dad, who was hunting around the shop for Softail brake anchor brackets. He greeted me and said something about shop organization. The Spitfire and American Made business model has faced serious transformations over the last couple of years.
As I mentioned before, Paul was the partner and manufacturing arm of Hellbound Steel motorcycles. American Made manufactured fast moving products for a bunch of now defunct companies such as WCC. At one time, they were building hundreds of choppers each month, and thousands of products in a much larger facility. During the last year, they adjusted their business model and tightened their facility. They rewired their building, replumbed it with compressed air lines, and kept building products.
It’s tough to stop everything and regroup, scour through boxes of tools, base material, parts, and junk. With a skeleton crew they are still building any frame a customer needs, including big twins, rigid Sporty frames, British custom frames, and even frames for Yamaha 650s and Honda fours. They also build an entire line of forward controls, gas tanks, handlebars, girders, and glide front ends (bowling pin), pegs, oil tanks (a variety of styles), trees and taillights. Paul is the mad scientist of the group. As a kid, he manufactured exotic gun cases.
He’s the kind of guy who will catch a notion in a cup of Starbucks coffee, in the morning and by the evening, he has a new product. It’s not a one-off either. It’s fully designed and configured for multi-manufacturing.
Some of his crew have been working with Paul and his dad for decades, including Larry, who is their master motorcycle assembly guru. He knows it all. “Pull the alternator rotor off that engine before you run it,” Larry told me. “Check the wires for twists or tears.”
I made a note. Then we made our way into the frame jig area to see the FXR frame progress. The FXR fever caught on and there were at least five FXR frames in the making. The first was based on the pro-street configuration with additional gussets, the squished wishbone, for the single-loop notion and 36 degrees of rake for a 2-inch longer girder front end.
They discovered some issues with my request for a V-style frame in keeping with the stock FXR configuration. I also hoped for less rake and a shorter Frisco style girder front end style. Paul was working on my unit with a 30 or 33 degree rake, but he also started building a couple of drop seat FXR frames, including one for himself.
We are also going to try a slightly longer swingarm suggested to us by Dar, the boss of Brass Balls for his FXR configuration. He wanted to pull the rear tire out of the frame some, and I was willing to try it. They are hot after these frames, since Paul plans to ride one on the Diablo run that kicks off on May 5th in Temecula, California and rolls toward the border. Don’t know if we will make it.
The plan for now is to pick up the frames, swingarms, axles, and Spitfire girders, on Friday April 8th. Between now and then, hopefully we will wrap up the engine and bring that puppy home to the headquarters. We are trying to match up these Mudflap Girl FXRs wherever possible, but not always. We are going to run long and short dogbone risers from Custom Cycle Engineering, but we’ve ordered a new set of Raw 2-into-1 performance pipes from Bub for Frank’s FXR, and I’m running a D&D 2-into-1 system. I’m running a Frisco’d and stretched tank and he’s running something completely different. He’s running a Klockwerks rear fender and I’m running something bobbed. I’m getting seriously ahead of myself. See you in a couple of weeks with the next report.

1928 Shovelhead Project Part 1
By Robin Technologies |
In an effort to stay tuned with the rapidly growing and ever changing industry the staff of Bikernet began a project Shovelhead several years ago in conjunction with Randy Simpson of Milwaukee Iron and Arlen Ness. It’s been a strange road, but we’re now rolling closer to completion with the assistance of Rick Fairless of Dallas Easyriders and his ace fabricator Jim.
The project began with the purchase of a slightly destroyed Mexican Police bike from Arlen a couple of years ago. He had scored some 300 1984 Mexican cop bikes that had been ridden through several revolutions and costly rebellions. The bikes were shot at, dragged, bombed and ridden harder than any V-twins on the planet. When we first purchased the Shovel complete with police sirens and blinkers, we assumed foolishly that we would restore it to it’s original fighting condition. Arlen even hand picked our unit specifically with our goal in mind.
Well it’s one thing to dream of a restoration, but when the cast iron triple trees are broken, the frame is bent, all the sheet metal destroyed we took a step back and said, Help! We pulled the Engine and sent it to JIMS Machine for a rebuild along with the Transmission. With the cases replaced along with the barrels and heads and all the internals replaced, the engine was ready to rock once more. A similar concoction was mixed for the transmission and a couple of us dressed all in black and prepared to bury the chassis in a shallow grave in the desert outside of 29 Palms, California when the Editor of “Biker” pointed out that we had a valid pink slip. Dean, salivating, over the dying chassis took the entire unit and paid us handsomely for the paperwork. We suspect that he made a rocking chair out of the frame and wheels. During one of our weekly Bikernet meetings we discussed what to do with the Shovelhead drive train, and in the process we started discussing various options and some of the customs we respected the most. Several suggestions were thrust onto the rusting boardroom table. First Randy Simpson had volunteered to help us build an old time looking bike from the remnants of the ’84. We voted unanimously to pursue this avenue, since we had always been impressed with the workmanship and design Randy injected into his own 1928 Shovelhead projects, and he had a desire to create a simple chassis kit to build one of these puppies to market to the public. We agreed to help him promote the concept. We also all agreed that a gesture to the community of San Pedro was a necessity since several members of the staff had been arrested and the headquarters were constantly under surveillance, so we decided that Bikernet needed its own private San Pedro Police bike. How else could we crash the local parades. Randy is a persnickety builder who takes great pains to build quality parts for the market. Two years passed and he still didn’t have the frame built. He was obviously so successful with his growing line of fenders that his chassis concept was slipping onto the back burner. Arlen Ness was also taking giant strides to build a similar machine and if you picked up a recent Easyriders you would have seen the fruits of his labor in his 50/50 Shovelhead. In addition Chrome Specialties with the assistance of Chico in Southern California had recently completed a similar project around a Sportster (It’s called Trick and is featured on Bikernet right now). The competition was stiffening. Randy dropped out, and we moved ahead, and with some research we discovered that a number of reproduction parts are being built in Europe for early Harleys. Early like in 1915.
Devoted to successfully completing this project we picked up a rigid frame from Paughco. This is a standard scale Paughco Rigid for Shovelheads. From there our old part contact was Fred Lange in Santa Maria California. Fred informed us that a European group is remanufacturing 1915 springer front ends, flat track tanks, headlights, fenders and Fred was making appropriate sprung seats for these models. We were in business. We ordered the flat track tanks, the fender for a side car so it could be used for the front and the rear, a hand leathered seat and snuck out of the hills over looking Santa Barbara.
We had a Bad Boy front end, Wheels, etc. We’re in the market for some Custom Cycle Engineering lowering rockers. At that point we needed miscellaneous parts, pipes, etc., and we could get this puppy on the road. It was time to call in a favor. Rick Fairless had purchased the exclusive Bandit I Pat Kennedy Built bike from Bandit and part of the deal was parts and labor on a bike project in the future. It was time to call in that note. Then in a stroke of bad luck and good, Marty Ruthman decided to close his shop abruptly due to health problems and he had a massive sale.
