This is strange. I’m writing several Sturgis Chop Techs after I returned from Sturgis. I’ll try to remedy that in the future, but we were so damn busy trying to complete the bike and run Bikernet, we didn’t keep up on the techs. Many apologies.

This piece covers the installation of the hot Speedster cap from Crime Scene Choppers in the modified stock XR 750 factory tank. Later, you’ll discover, that this highly modified, strengthened and extra rubber mounted beast was my Sturgis nemesis. But more on that later.

We added rubber-mounted bungs to the back of the tank. I moved the petcock to the rear and filled the center for a 2.76-gallon gas capacity before it hit reserve. I doubt that it contained more than a quarter tank of reserve, so I’ll toss it a 3-gallon total gas capacity.

Oh, I need to thank Cyril Huze, who designs beautiful steel tanks for the opportunity to experience an aluminum tank once more. He suggested this classic for the Sturgis effort.

Don’t ever run an Aluminum tank on a rigid frame. You’ll be asking for problems.

I’m not holding it against Cyril. He’s a master and I’m the bungler for attempting aluminum on a 93-inch rigid S&S hot rod. As you’ll see the vibration aspects came from several sources that I could have remedied. It’s all just a roll of the dice.

When I received the Speedster cap I drug the cap and tank down the street, about three doors, to Bill Hall’s Welding. He handles my aluminum welding, since I don’t have a TIG welding system. I’ve got the rest, but not TIG. I would highly suggest a TIG system for quality welding capacity and good looking welds. It’s much like welding with a torch, so you’re certain of the bead and depth of penetration.

Bill’s a retired designer who enjoys welding and fuckin’ with his customers. “How are you going to drill the hole for the bung,” he asked?

I was thinking about die-grinders and files. I knew it would make a mess. Bill hooked me up with a 3-inch hole saw. He suggested that we hit a marine store for a tapered dowel pin (used for plugging holes in the leaking hulls).

The key was to drill a perfectly centered ¼-inch hole to maintain a center approach to the cap bunghole. I drilled it and then ran the tapered wood dowel into the tank.

Then we set the tank on a pad on the drill press platform and lined up the hole saw. I used plenty of cutting oil on the edge of the blade and aluminum face to prevent the tank from snagging or catching. I knew how tender the surface of the tank was. We oiled the hole in the tapered wooden plug and carefully went to work. Bill’s formula worked like a charm.

Next, we needed a tool to hold the Crime Scene Speedster bung in place. I grabbed a piece of strap, drilled a hole or two and mounted it with the supplied hardware, which was brass. You can order the cap with several styles of fasteners for your application.

It was off to Bill’s for welding. While the gaping 3-inch hole was available I could have made a tapping tool and tapped out any imperfections in the tank walls. I dinged it way back in the beginning and never got around to fixing it. I left her be, as if it was the first injury and she needed to stay. I know it’s one of those wild superstitions.

Okay, so during the “read the directions” phase, I noticed the bit about a non-vented tank. I would need to drill a tiny, cunt-hair hole in the cap of the tank. I discovered that I actually had such a tiny fuckin’ drill and dug it out. I had to find a chuck that pinched down to that size. Then I had a wise ass notion to drill the initial hole about 1/8 inch in diameter, since drilling with hair-thin bits causes easy drill bit breaks. The thinner the surface the better.

So, I initially drilled the inside of the cap with a 1/8-inch drill and drilled right through—Bummer. Ultimately I tapped the cap with a 10-32 then drilled the stainless Allen stud with the tiny drill bit. Then I screwed the stud into place and the job was finished.

After Bill welded the bung into place it was my job to grind the welds down and ship the tank to Foremost Powder for a clear coat. I hit the big spots with a grinding tool. I tried my damnest to take only meat off the welds and not off the surrounding tanks surface.

Next I used small emery discs to carve at the aluminum bead. I also smoothed some of the welds on the front of the tank where we filled the tunnel for additional gas capacity.

This shows the different grinding phases to reach a level that’s still strong with weld bead but handsome enough to live with. This was an interesting effort, since no bondo or thick urethane would be applied, covering a myriad of mistakes. This was the final stage before clear powder from Foremost in Gardenia, California.

After this stage I polished the panels of the tank and hauled it off to the powder masters. There’s one other process I need to explain. I made every effort to clean the tank of debris and shavings. I also made sure to run a gas filter. I still had problems, which I will explain in my Sturgis Saga. They were easily remedied through Lee Chaffin at Mikuni. Just needed to dial the right number.

This shot was taken after powder and pin striping when I installed the gasket, decided which direction I wanted the cap to face and screwed the brass fasteners down. The cap worked flawlessly all the way to the Black Hills.

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.

Illustration by Tim Conder.

I'm attempting to build the ultimate handling chopper. It's not designed to be a show winning, bitchin looking, artistic masterpiece. I'm going another direction, attempting to build a righteous, old school, performance, handling, and reliable machine. No, it's not a Martin Bros job, and from an artistic standpoint I believe they are the ultimate builders. I want it to fit me, handle like a dream and last forever. We'll see.

Inside the Paughco powder coated springer rocker.

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.

We tried to find the smallest, strangest, most effective Custom Chrome headlight available.

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.

This is the springer axle and spacers available from Paughco.

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.

Custom Cycle Engineering risers in place with studs.

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.

Here's the CCE risers with 1-inch longer, tank clearing, stems . I don't throw away a goddamn thing. I had these laying around from another bike project. Worked perfectly. I'll black powder them before it's all done.

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.

Here's a Doherty front axle spacer in place. What a dream it is to have a kit of varying lengths at my fingertips. Actually, a girl named Bree would fill my dreams more appropriately, if you know what I mean.

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.

Bikernet Warning: When mocking up your ride don't sweat the wheel spacers just yet. Install the wheels as close to center as possible, but keep in mind the slop before you install your fenders only to discover, under final spacing, that the fender is out of whack. Beware

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.

Again the Doherty spacer kit made my midnight working conditions shine. It comes with a variety of spacers from over 2 inches to 1/4 inch polished aluminum jobs.

Here's the CCI chain sprocket. I like the old school notion, O-ring chains are reliable and not sloppy, and I like the size that's not an obstacle to view the wheel.

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.

I bolted on the Joker controls and the Custom Chrome kick stand to easy parking if the bikes was removed from the lift.

The stock XR Sportster racing tank in place.

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.

Here's the new petcock bung hole drilled at the rear of the tank for maximum capacity.

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.

I'm not going to attempt to weld the tank. Just up the street is a 40-year pro, but I need to have all the parts and pieces ready to weld.

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.

I made sure to bevel the holes slightly to prevent a fit with the rubber and insure the steel wouldn't cut the soft material.

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.

Here's the tabs ready to rock.

I used a level on the frame, ultimately on the front motor mount then on the top of the tank to make sure the tank was level with the frame.

At 1:00 a.m. I turned in, but just before I tacked the tabs to the frame and used my air hose to cool the tabs, so I didn't smoke the rubber sleeves. I discovered in the morning light that the tank wasn't in the center for the frame rail, and it needed to be dropped 1/8-inch in the front.

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?

I'm not sure about this operation. I drilled several holes in the tunnel for gas to flow in and out. I hope it's cool and enough flow. Any suggestions? I didn't cut the tunnel completely out for structual reasons. It's an aluminum tank on a rigid frame. I don't want it to crack between here and Sturgis.

After positioning the bungs and petcock several times, I decided to run the Petcock back as far as possible for the most gas capacity. Then I positioned the round tab forward enough to clear the petcock.

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.

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.

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.

It doesn't hurt to take shots as you tear an engine down, to keep track of what goes where.

This engine was already set to go with a Compu-Fire single-fire ignition.

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.

Get a bunch of clean boxes to store and sort parts for final assembly.

Remember, you can't remove the pump body without taking off the shaft clip ring.

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.

Place all the oil pump crap in the same box.

Here's one of those little bastards. Don't use them again. Get fresh ones.

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.

There's another key and clip on the inside of the cam case to remove the oil pump drive shaft.

Here's the keys that drive the pump gears. The fuckers are tiny, so don't lose them. You can use them again.

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 was forced by the gods of Permatex to use a punch through the lifter stool hole in the case to reach the back of the cam cover to encourage its departure.

I devised a careful piston holder to prevent them from banging around. You don't want to damage the cylinder base area on the cases. I had a tool for this years ago, but it left me with one of my wives.

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 devised a tool for removing the pinion shaft nut, which is left handed.

Here's that bastard removed from the threads.

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.

I did dig out a puller that worked to snap that gear loose.

Here's the key that holds that gear in place. Don't lose the bastard.

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.

Here's the last keeper ring on the oil pump shaft on the pump shaft.

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.

The alternator rotor came right off.

You get the opportunity to operate with surgical precision digging out the flat coil keepers that hold in the wrist pin and the pinion roller bearing cages in place.

The Stator is easy to remove once the locking plates are punched out of the way. But make sure to back out the case Allen set screw before you pull the guts out of the plug (below).

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.

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.

These will no-doubt be removed and relocated to the seat post for a more secure, less vibration connection.

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.           

The bitchin Rohm oil cooler/filter mount.

The Rohm oil cooler/filter mount comes with all the mounting fasteners and fittings for oil lines.

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.

Right pipe complete.

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.           

I'll install the Empire internal throttle next week. It's driven on needle bearings, empiremfginc.com.

Ride forever,

We've developed a working relationship with S&S, and I was concerned about the 105-inch Shovelhead Richard Kranzler scored for my Sturgis Chop project. His motorcycle ran like a raped-ape, but the 105 tore the livin' shit out of his old school chassis. The mirrors became frisbies, the footpegs vibrated lose and ditched him at 125 mph on the freeway. The stress was more than the old swingarm frame could take.

Hot Rod engines are cool but will beat the shit out of a solid mount frame configuration. The best bet is to let them stretch out in a rubber mounted chassis. I called S&S to see what they would recommend and they suggested a smaller 93-inch configuration. James Simonelli put me in touch with Steve George, a 10-year S&S veteran, who said under his breath that they prefer not to mess with engine configurations other than they're own, but he would look mine over.

Made a lot of sense. S&S now builds a complete line of Shovelhead engines in four configurations: Two cone motor and two generator style. Each are available in 80-inch and 93-inch power configurations. Here's a description of their new units:

With the addition of the new S&S billet Shovelhead style rocker boxes and tappet guides, along with new pushrods and forged roller rocker arms for Shovelheads, S&S can now offer complete Shovelhead style engines. These engines will be available in 2005

S&S Shovelhead style engines feature the finest parts on the market today. Start with the bulletproof crankcases, flywheels, cylinders, and heads that they've offered for years, and finish the engine with new premium valve train components. S&S billet gear cover, tappet guides, and rocker boxes look outstanding and offer the performance level Shovel builders have come to expect.

What you can't see inside the engine is just as impressive. The new S&S Shovelhead style tappet guides are designed around the quiet, dependable Evolution style tappets. Corrected tappet guide bore geometry assures correct valve timing using Evolution style cams. The unique adjustable pushrods are collapsible for easy removal and installation, but are stronger than our old style adjustable pushrods.

Inside the billet rocker covers are S&S's exclusive straight rocker shafts and the new S&S forged Shovelhead style roller rocker arms. The result is a Shovelhead engine with the kind of quiet power that some folks may just have a hard time believing.

A new addition to the S&S Shovelhead family is the 93-inch alternator/generator engine. This is the perfect engine for that “retro” chopper, but with a modern alternator charging system.

In addition, the late style sprocket shaft used in this engine allows the use of late style transmissions for additional modern functionality. So when you take your chopper out for a late-night cruise, and you want to see the road ahead as you click `er into 6th gear, this is the one.

Note:S&S Shovelhead style engines equipped with S&S tappet guides and tappets will be supplied with an Evolution style camshaft. Custom engines ordered without S&S tappet guides and tappets will be supplied with a standard Shovelhead style camshaft.

My engine was equipped with House of Horsepower cases. We used the same bore (3 5/8-inch) but S&S barrels and pistons with a 4.5-inch stroke (instead of 5-inch stroke). Stock bore is 3 7/16 and 3 1/2-inch for all 80 and 88 inch engines. This operation basically involved a S&S Sidewinder kit, including (left to right) cylinders, pistons, crank pin, connecting rods, cases and flywheels.

First Steve assembled the short block which was balanced to a 1300 bob weight for smooth operation and reliability. The S&S forged pistons are 8.2:1 compression with longer skirts for longer lasting reliability.

Then he assembled the wheels in the left case with fresh Timken bearings. My cases needed a ledge bored away for the longer skirted S&S barrels.

Next the other side of the case was slipped over the pinion shaft roller bearings and the lower end was complete. The flywheel weight is approximately the same as stock Evolution (lighter than Shovelhead wheel) for a balanced running engine and added reliability.

Ah, next came the pistons and barrels. I know we don't have all the details here, but at least you can see the big steps in building an engine. It's not tough but takes precision workmanship and quality components.

I'll be using a Compu-Fire single fire, dual coil ignition.

The final steps before shipping included the S&S oil pump installation and the cone cover. I'm returning a Compu-Fire ignition system to the cone in short order.

The engine is now at Phil's Speed shop. He're rebuilding the heads and will install S&S roller rockers, shafts, new Custom Chrome Black Diamond valves, new lifters (with bored-to fit lifter stools) and pushrods. Hopefully it'll be completed next week and ready to set into that Paughco frame. Then I can start bending pipes and making shit.

I've worked with Paughco for over 25 years, for quality frames and front ends, then this frame arrived and the tranny wouldn't fit. I had a 4-speed tranny plate that the JIMS trans slip right into, but the holed in the frame didn't align. I spoke to my tech guru, Frank Kaisler who contributes to Hot Bike, Street Choppers and was the editor of Hot Rod Bikes. He lives tech. Of course he pointed out that I needed a first electric start vintage plate. I had a late model, dipped, single sheet plate and the 4-speed job and neither worked. So I sat as my desk and poured a glass of jack. I had the bike buildin' blues.

Here's the famous Bikernet Desk. I made calls about the tranny plate, unsuccessfully and slugged that amber liquid until my brow bounced off the glass top and I spied the tranny below–on the wrong plate. I couldn't believe it. All these years that desk ran with the wrong tranny plate, and it just happened to be the one I needed.

Here's both tranny plate together. The thick one with two slabs of steel is the original 4-speed job. The single, bent-in-the-center sheet with the four frame mount spacers was designed for the first electric start transmissions beginning in 1965.

Finally the JIMS trans is in place with the proper mounting plate, and I was ready to move onto mounting the oil bag.

At last, after 15 years I installed the correct tranny plate into my desk. Damn, I'm embarrassed.

The rear fender is on it's way from Lucky Devil and I installed the Kraft Tech round oil bag last weekend. Movin' right along. You'll see that tech shortly. A new oil cooler/oil filter set-up is on it's way. It's a must for making the old iron last.
