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.

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 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
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,

5-Ball Factory Racer Closing in on New Cam and Ignition
By Robin Technologies |
We were fortunate to hook up with Heather New, of New-Line Engraving several years ago. Since I was about to switch out my CrazyHorse engine ignition with a Blackhawk Motorworks cone cover I needed to come up with a classic point cover for the new unit and the 5-Ball Factory Racer. It was a natural choice to send her a chunk of aluminum, or I shoulda sent a piece of brass, but oh well. Either way I knew she would bring the project to life.
Heather started engraving in a small shop in downtown Edmonton in the Early 80’s, where she took care of over 100 jewelry stores. “I was engraving everything from I.D. bracelets to wine goblets to pocket watches, and more,” said the raving redhead, “items which other engravers said could not be done, I soon learned to do!!! This was when I first met Frank.”
Frank Gurney was (and still is) the best Hand-Engraver in Canada. “He is a true artist and craftsman, and along with the Alberta Apprenticeship Program, arranged for me to be his understudy,” Heather said. “I was thrilled!!! I learned so much from Frank in those years, confidence, trouble-shooting, and above all HUMOR!!!! We spent hours working and laughing (hoy-deedle-doy!!). He taught me so many things before he eventually retired out near Victoria, B.C.”
She then moved on to the largest Jewelry stores in Canada. “I was doing all of their machine engraving, as well as custom wedding bands, and one-of-a-kind jewelry pieces,” Heather said. “They treated me like gold, and I will always be thankful for the kindness I experienced there. I relocated near Calgary, Alberta, and began working for a gigantic company with more talent than I had ever seen gathered in one place. I naturally did the engraving there, and also moved on to operating CNC machines, and hand-carving moulds used in casting.” She became a programmer, writing the programs, which would later be used by the CNC machines to cut the actual moulds.
She started New-Line Engraving in the summer of 2005. “I hand-carved an inspection cover for my good buddy ‘Chicken’ and with her over-whelming encouragement, (she cried when she saw it) I decided to branch out into custom bike carving too (after all, a derby cover is just like a signet ring, only BIGGER.”
So here’s how the short, two-week process rolled:
Cover the piece in white water-soluble paint, and transfer the artwork onto the surface
I highlight the general outline, scratching the paint leaves a more permanent mark than pencil, and you don’t rub it off as you work!
For removing large areas you can try a dermal, but they tend to vibrate too much for any fine work…I used small gravers hooked into a pin-vice to cut in between the letters,
as this cover was done mostly under a microscope.
I also use fine sandpaper, jeweler’s files, and burnishers to “round-off” curves (as seen on her legs), and give some dimension to whatever artwork you are dealing with…
Details like hair, the features in the face, and fine shading are all done with fine gravers and files.
I then add an aluminum-oxidizing agent, which blackens the entire piece. When it is re-polished, the highest surfaces will become shiny again, while the black remains in all the nooks and crannies of the background. (I only do this by hand—a buffing machine can remove hours of work in a heartbeat!!)
“If anyone out there in Cyberspace wants to give it a whirl, I am always here with support and tips,” said Heather

Sturgis Shovel Part 7
By Robin Technologies |
Brembo has a solid worldwide reputation, and I ran into a hot looking Brembo representative at an illustrious bike function and decide I’d give them a try. They’re hot and ready to rock. The only items I needed were the locking nuts for the back of the rotors bolts and the springer axle spacer. This set-up was designed for a stock springer replacement.
Because of the wild, light, taper-legged Paughco Springer my hiem joint link wasn’t long enough and I bastardized two fine bolts together temporarily. At that point I wasn’t considering a front fender. There are two aspects of chopperdom that I have a tough time working around. Bikes need front fenders and brakes. Can’t ride ‘em much without those two bastards. Even in the old days I ran front fenders, Avon Tyres and front brakes.
Chris Kallas came over at just the right moment. He’s as old at riding as I am and an artist. We’ve featured his work in special reports. He knows his bike shit and I’ve been trying to convince him to see Jim Murillo about a job. Jim has a paint shop in Torrance, but he’s not the graphics guy, Chris is.
As usual, about the time I think it’s going to be easy, the devil pops up on my shoulder. Kent, from Lucky Devil Metal Works in Houston called, “What are you going to do about a front fender,” he said? “Yeah, that’s what I thought. I’ll send you some shots of my springer front fenders.” He hung up and Chris looked at me sorta strange.
”Who the hell was that,” he said?
”Never mind,” I said flipping my computer on. Kent developed a system of mounting springer front fenders that’s clean as a whistle and odd as only the devil would make it. An engineer wrote Bikernet when I first featured his wild notion and chewed us out. “That idea’s not worth the powder the blow it to hell,” he shouted.
At first I thought he was correct, but the more I considered it, the more I determined that he was wrong. The caliper follows the line of the rotor, so the fender will follow the circumference of the Avon tire. Of course when I stepped into the ring to create a similar configuration I couldn’t do it like the Devil does. The Brembo caliper runs too far ahead of the rotor to mount the fender so we ran carefully designed struts off the brake linkage. Chris drew up the plan, then bent struts out of coat hanger for a guide.
We constantly tried fitment again and again before tacking them into place. I wouldn’t recommend this configuration to anyone. If you run struts off the caliper they’re solid. The heim joints allow the fender to fluctuate, especially side to side. I had to find a concave washer that would allow the heim joints to work up and down but not side to side.
Chris bent each rail to match in pure artistic form. Then I tacked them.
Kent built the front fender with threaded aluminum bungs underneath. I figured out some slender spacers to fit on top of the fender and tacked the rails to them. I must have welded them a dozen times trying to grab just enough rail, weld and spacer to prevent cracks.
There you have it. It’s wild, but will it last to the Badlands?

Sturgis Shovel Part 8
By Robin Technologies |
My first move began with a correction. I removed the exhaust pipe tab welded to the oil bag. The oilcan is rubber mounted, the exhaust pipe generated severe heat and the pipe system needs to be solidly mounted. It had to go. Actually Kent from Lucky Devil Metal Works in Houston tried not to mention the false move, but his frown gave it away. Or was it that question? “Is your rear pipe really mounted to the fuckin’ oil bag,” Kent said tentatively?
I discovered that the pipe exits the head close to the seat post and worked on a pipe connection there. There are a couple of rules in making pipes that I need to abide by. I needed to remove the pipe once in awhile, so I needed the pipe tab to be on the outside of the frame tab. Often mounting required slack, so I dug around for 1/16-inch washers to run between the tabs. That way when the fasteners are removed there’s some slack to pull the pipe free.
I worked with the pipe fully in place then tacked the seat post tab. Below is the tab tacked to the pipe. Then the tab welded in my shitty MIG welding fashion. I should slow down and clean the base metals more. I generally grind a bevel into the tabs for greater weld penetration. The welds are strong, just not handsome.
Next I needed to attach the Lucky Devil rear fender, align the rear wheel and cut the chain to fit. But first I needed to center the wheel in the frame, sorta. The custom Paughco frame is designed and manufactured to hold a belt pulley and a 180 Avon Tyre. That prevented me from measuring between the frame rails. I needed a straight line down the center of the frame backbone. It’s not incredibly accurate but close to draw a fabic or nylon line down the tube. Then with Doherty space kit and the seal spacers that came with the Custom Chrome aluminum and stainless spoke wheels, plus the Brembo brake caliper bracket, I aligned the wheel.
Before I cut the Rev Tech chain I installed the BDL Belt inner primary and pulled the engine and transmission into place which determined exact spacing. I know I covered this aspect somewhat a couple of chapters ago. There’s been some heavy drinking in the meantime, so if I lose track, it’s on Jack.
I centered the wheel in the chain adjustment slot to give me slack either way. Then I finally cut the chain with a JIMS tool.
I spoke to a couple of guys about sprockets and was told that this contraption will hold a sprocket nut from coming loose better than simply Allen screws in the Custom Chrome sprocket. I may use it or not. Haven’t decided yet.
The reason this is altered is that it’s for a pulley and a different era. Add that to the fact that I flopped the dished sprocket over to space the chain away from the tire. That aspect worked perfectly.
I decided that since the tank was rubber mounted and aluminum won’t flex as well as steel that I would attempt to rubber mount aspects of rear Luck Devil fender. Kent designed and handmade the fenders to match aspects of the XR 750 tank.
Cyril Huze sent me several grommets to work from and this pair are from some late model Sportster application. I measured the O.D. on the center portion and discovered that I needed ½-inch holes in the fender which I drilled after I had mocked up the fender in place, ground a clearance strip for the chain and stood back several times. Arlen Ness once told me that he used a chain wrapped over a tire to space a fender. I needed enough space for fasteners under the fender and some chain adjustment slack either way.
I moved the fender up and back, and side-to-side several times before making any hole-drilling marks. I was a nervous wreck. Ya don’t mess with the Devil’s fender. I finally drilled a half-inch hole, and smoothed the edges, in the bottom of the fender then at the crossover tube. I worked in the rubber with a dab of oil and bolted the bottom stainless bolt in place.
The Sportster grommets have metal inserts, which make them easier to install. With a couple of spacers in place the fastener held the center tab for tacking.
Here’s where it got tricky. I’ve been bending metal with a torch for years. Never improved my technique. Just the other day, a month after I built this fender rail system, I bought a small strap or tube-bending tool. Wish I had it when I went after this project.
First I built the fender strap out of a piece of exhaust pipe bracket. It came with two 3/8-inch coarse tapped inserts in each end. My plan was to build a fender rail system with tubing so I could adapt a couple of running lights on the tips. I carefully bent and drilled the strap and fender.
Then I bent the tubing fender rails to fit over the chain and tacked tab to the Paughco frame. One item I often attempt to use is a level. I’ll level the frame from side to side, then strive to keep all the other elements level. It helps.
Here’s a perfect example. As I finished my welding chores, I got on a roll. I thought– wouldn’t it be cool to weld the fender bolts in place from the bottom. They would never come loose. Note the angle. There was no way they would ever return through their mounting locations. I was forced to grind them off and clean the holes.
Here’s the finished fender rail system. I drilled holes in the frame and the rails to run wires. I still haven’t found the perfect running light style that rocks my boat and will afford me enough room to use the proper fasteners. Hang on!
Sturgis Shovel Part 11
By Robin Technologies |
I’m not sure if I’m keeping everything in line. But this segment took us to Foremost Powder Coating in Gardena California. I was at that point when these shots were taken. I’ve had a Powder Coating Sponsor for years, Custom Powder Coating in Dallas. They’re good people and know how to handle custom work. They’ve handled jobs for Strokers Dallas, our custom for American Rider and even the 1928 Shovelhead for Bikernet.com.
Powder coating costs have dropped and it doesn’t make sense to ship a frame to Dallas. It would cost less to have it Powdered in LA than to pay for the shipping. So I looked around the area and was recommended to Foremost Powder Coating (877) We-Coat-it, 1608 W. 139th, Gardena, CA 90249. These people have their shit together and the girl who runs day-to-day operations, Esmeralda, is a delight on the eyes and to work with.
Let’s back up, though. Just before teardown for Powder I needed to think electrics. Kent from Lucky Devil Metal Works in Houston sent the above illustration for mounting the Compu-Fire voltage regulator under the tranny with the small Dyna Coils from Custom Chrome. I pondered that drawing and decided that I didn’t like the notion of putting my coils at ground level. What if I ran through a rain puddle? He’s built bikes using this technology several times and so has the guys at WCC, so it must work in most circumstances.
I decided that since I was going to run the Compu-Fire engine based electric starter that I had room under the oil bag for the coils. I still installed the sealed voltage regulator under the tranny on a 3/16 sheet of aluminum. But then welded brackets under the Craft Tech Oil bag to hold the two coils apart.
This was a delicate operation and ultimately the new Accell Sparkplug wires run right across the top of the RevTech Tranny. I also had just enough room behind the coils to house the wiring for the single-fire Compu-Fire ignition system. I thought through most every aspect of this motorcycle right up to the wiring business, then came up with a nuts notion, which I will explain during the final assembly process. It actually worked out fine with a handful of scary moments.
I welded four bungs that housed 3/8 fine threads to the frame with my Miller MIG welder. Ultimately I mounted the Compu-Fire voltage regulator to the pipe side (right) and it worked out fine.
It was time to strip the Engine out of the frame, complete final welds, grind the welds and ship the parts to Foremost Powder. I needed to create a temporary engine stand to hold the S&S 93-inch Shovel in place. I used a RevTech engine stand and mounted it to a junk metal table leg. It worked perfectly and I shoved it in a corner for future use.
As I tore portions of the bike down I formed zip-lock bags with labels to hold the fasteners. You’d be surprised how fast you forget which spacer fit what, unless you organize. Mike Egan told me years ago that he takes photos of every part and organizes his assembly with photographs to demonstrate how components matched or were fastened. Since I try to take shots constantly I had an archive of various aspects. Hell, I just need to turn on Bikernet and look up the tech.
The next move was to finish welding any tab or bracket that had been tacked or partially welded. MIG welding is a breeze, but not as dead certain as TIG and I’m after a Lincoln TIG welder.
Here’s all the fasteners, grommets and spacers in bags with biz card labels. It works like a champ although I replaced some of these fasteners with stainless Allens wherever possible.
Next I dug out all my tools for grinding welds and went to work. This level takes a great deal of patience and artistic style, which I don’t have. The more time and patience, the better each weld will look. There is actually a process for bondo filling powder now, but it’s more costly. If you don’t want welds to show ask about it. If you don’t mind the look of a clean weld, just powder. I wanted the look of a machine, nothing slick.
There’s one more consideration. Try to make each weld look the same as the next one for consistency. In my case that was tough. Some of my welds were decent, others sucked. I did my best, but my welds didn’t compete with the Paughco paid professional beads.
As I finished grinding and drilling holes in the frame for wiring I separated each group of powder finish parts and took a shot for the Powder guys at Foremost. It was a lifesaver to be able to hand them a shot of each group of parts since some had to be sand blasted before the finish was applied.
One more comment on drilling holes for wiring. This was one of the first times I drilled plenty of wiring holes. Remember Frank Kaisler’s rule? Drill the hole. Ream it out on a taper to prevent cutting your wires. Then with emery cones make sure there are no razor-sharp burrs in the tubing. Frank ran the emery paper then he’s twisted a Kleenex and shoved it in the hole. If it caught he’d sand the edges more. If not it was good to go. Let’s hit it to the next chapter, we’re burnin' daylight.
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.
