Hang on. This is the last of the scintillating segments on
building the Sturgis Shovel before I write the treacherous saga of
the ride. Somewhere we will publish a feature on the bike in a
mag and on the site. Oh, there’s one other tech that will come to
pass—hard line assembly. I’m waiting for a CD of images from
John Gilbert of Bike Works mag.
Fasteners organized and ready for final assembly.
So let’s get started. I was burnin’ daylight before the
Sturgis run. I saved a ton of cash going with all powder and no
additional chrome or polishing. It cost me just $325 to powder
all my components for lasting protection.
Throughout this article I will point out my mistakes, so you
can avoid them. I did an 80 percent decent job of mocking up
the bike prior to powder. That meant that 20 percent had to be
dealt with after the finish was applied. Bad news. The only thing
I didn’t think through or make brackets for was the ignition
switch and circuit breaker brackets. That may seem minor, but
wasn’t as you will discover. On the other hand it wasn’t a big
deal. You be the judge. Actually, if we wired, fired and rode the
bike before final teardown, it would answer all the questions. But
few builders take it that far.
I was jazzed to toss the Paughco Frame on the lift covered
with pads. Foremost Powder had plugged all the threaded holes
and tapped off the neck bearing surfaces. They did a helluva job.
I shaved motor and transmission mounts for a proper ground
and installed the S&S modified 93-inch engine and JIMS trans.
Then I could install the Paughco Springer without a balancing
act.
The Springer is easy to install, but takes care. I greased the
bearings, slid on the dust shields and ran the whole springer
through the neck. Keep in mind that installing the bearing races
in the neck is not complete until the bike has been down the
road. Any paint, dust or uneven race angle will mean that the
bearings will seat further once on the road. Ride it for a week
then lift the front end off the ground and jiggle the wheel by the
axle. If there’s any movement or dangerous slop, take the bars
and top tree off once more and tighten the stem nut until there’s
just a hair of drag. Long front ends are more critical because of
the leverage against the neck.
That’s the nut that needs to be tightened.
I didn’t bolt down the engine and trans hard, just the tranny
plate which ultimately I had to loosen. The engine needs to be
completely at ease for the BDL belt alignment so I just spun
some stainless bolts into place. Then I installed the front wheel
with Doherty spacers, the Brembo brake caliber and centered the
wheel. Keep in mind that Brembo supplied the bracket, which is
designed to replace a stock, late-model Harley springer brake
system. I didn’t have the proper spacer, but a Harley shop had
one and I was good to go.
Then I installed the Brembo Caliper. They supplied me with
a series of shims. I used feeler gauges to determine centering
the caliper over the rotor and stacked the shims until it was set.
This is an interesting bumbling, experienced manner for writing
articles. I have the insight of riding experience behind images of
the bike yet complete. Ultimately we removed the front fender.
I build the front fender, single sided bracket after Kent’s,
from Lucky Devils Metal Works in Houston, caliper mounted
fender mounts, which work perfectly. My problem was the initial
position of the caliper, too far forward. So I mounted it on the
heim joint rod which didn’t work. When the bike went over a
bump the front lip of the fender rode up with the caliper and the
rear lip rode down with the springer touching the tire. It had to
go. So I rode to Sturgis without a front fender ducking
rainstorms all the way.
Next I installed the rear fender. Keep in mind that the rear
fender, the oil tank and the rear wheel fight for the same spaces.
They almost need to go together simultaneously, especially the
oil bag and rear fender. Everything slipped into place with nyloc
nuts, stainless Allens and red Loctite.
At the time I ran stock gearing with the JIMS 6-speed, until I
discovered that I was faced with running a kicker. I didn’t
change the rear wheel gearing from the 51-tooth, but I should
have. This evening I’ll install a Custom Chrome flat (Sportster
styled) 48-tooth sprocket and hope to knock the revs down
seriously.
I also mounted the rear Brembo brakes and centered the
caliper over the Brembo rotor. No problem. Even my Softail
styled anchor bracket worked perfectly welded to the frame and
tucked the caliper between the frame rails.

While I’m messing with brakes I’ll cover brake and clutch
lines and cables. Instead of making up lines I ordered RevTech
pre-assembled lines from Custom Chrome plus all the fittings
washers and fasteners. Keep in mind that the front brake master
cylinder uses larger master cylinder banjo bolts. They come in
10mm and 12mm. Watch out, and don’t hesitate to order a
couple of extra bangos bent at different angles to make sure
you’ll have what you need.
I measured my lines and clutch cable lengths a number of
times then added an inch for safety. That’s where making your
own lines can be helpful. Keep in mind that the front end will
turn (clutch cable) and depress (front brake). You’ll need some
slack. Plus you might change the angle of your handlebar levers,
which will impact the position of the cables and lines. I used
Tephlon tape on most fittings although some builders don’t
recommend it. Since most of this stuff is chromed, I like the
extra sealant.
I use only DOT 5 brake fluid in my bikes, ‘cause I can
splash the shit all over the place without concern for paint
damage. In many instances you can fill the master cylinder and
rock, just by waiting for the bubbles to rise. Another key is to
find the right pump can and fill the lines, caliper and master
cylinder from the bottom up. Use a new pumper or a pump
that’s dedicated to brake fluid only and attach it to your brake
bleeder on the front wheel. Most of the time that works like a
charm.
I’ve found that most front brakes will basically bleed
themselves. Fill the master cylinder on the bars and pump it
slowly allowing the bubbles to rise. Let it set overnight and most
of the bubbles will rise just by pumping it with short strokes at
the lever and watching the bubbles jump to the surface.
In this case I discovered that some air was trapped in the
caliper, so I pulled it off the bike, taped a file (the same width of
the Brembo rotor) and turned the caliper so the air could escape
through the bleeder nipple. I bleed it a couple of times then
returned the caliper to its rightful position. She was good to go.
The rear brake wasn’t so easy because the air couldn’t rise
to the master cylinder. I bleed it from the front and the rear, and
I think it still has air in the lines although the Brembo brakes
worked fine. I received a lot of compliments and comments on
the brakes, which I found strange. Brembo has a terrific
reputation, but not on Harleys. Riders were surprised to find
Brembos on a Chopper.
Now for the clutch cable. First I was confused about which
cable style to order. I hope to put together an article on it in the
near future. I picked the most common late model Evo cable and
measured the length several times. Here’s the key. If you’re not
replacing a stock cable you have no notion of the length. I pulled
a stock cable and measured it, but I didn’t know what model it
came from. I went by the length of my stock cable and found the
1990-1999 Fatboy cable length. Then I measured the extension
due to the Paughco Frame, CCE risers and CCI bars. Much guess
work. If I had all the bucks in the world I would have bought
three cables lengths.
The end cap cable is the reason Baker, JIMS and RevTech
transmissions come with a fresh gasket and a quart of
transmission oil. They know that you’ll be forced to pull the end
cap to install the cable in the ball driven throw-out bearing
mechanism. It’s simple but cumbersome. Don’t loose the balls.
You’ll need a massive C-clamp removal tool to pop that sucker
free. Carefully lift the inner ramp and remove the cable coupling,
attach the cable, which you have already screwed into the trans
face cover. Return the coupling to the inner ramp by watching
the puzzle face. Then put the ramp back in place and the
retaining ring and bolt the face cover back into place. Don’t
forget to add at least 20 ounces of Trans fluid. It will hold 24
ounces dry.
I learned something on this trip. If water gets in the trans it
will act up, shift strangely. Drain the fluid and change it. Check
your vent.
I ran the cable several ways to find the path that fit
best, didn’t rub the frame or catch on anything. I used one Arlen
Ness cable clamp to secure it and hooked the cable into the
greased tephlon bushing in the Joker Machine handlebar control,
then replaced the small C-clamp and I was ready for final clutch
cable adjustment after the BDL primer was installed.
JIMS 6-speed transmission is place.
Here’s where a Twist emerged.
B>
I’m going to cover the 300 BDL installation here and
try to explain my shift. My plan was to run the Compu-Fire
engine based electric starter system designed by Giggie before
he left and took a job at Rivera. Rivera is making inner primary
plates for this new system, but when I contacted them Ben
Kudon’s response was hesitant. They weren’t ready. Of course I
contacted our long-time sponsor BDL and initially they weren’t
scheduled to make units, then I was pleased to find out they
were, so I ordered one. But Sturgis crept into the picture, and
suddenly I was without a starting system and coils hanging
under the oil bag interfering with any new starter install.
I had a 300 BDL belt system and a starter but no place to
put it. Kent from Lucky Devil shrugged his shoulders and said,
“Why don’t you run a kicker?”
Sinwu ripped off her top, jiggled her tits and said, “You have
one from Muller in Germany.
I jammed down the headquarter stairs to the shop and tore
open the box. I was jazzed. This is one of the coolest kicker
systems to come along. It cleared the rear exhaust pipe and the
kicker arm was stylish, unique and strong. I couldn’t believe my
luck.
This bearing retainer plate needed to be removed before the
trap door could be pressed off.
Another JIMS Tool at work.
The JIMS 6-speed lined up with the BDL inner primary like a
dream. All I needed was to pull the tranny face and press off the
trap door, then replace the trap door and tranny cover with the
Muller system. Muller even shipped a clutch ramp system that
afforded smoother clutch action.
Hell, I’d even build a cool brass plug to cover the speedo-
cable hole in the side of the JIMS trap door.
JIMS 6-speed gears protruding from the late 4-speed
case.
All went well until I removed the JIMS trap door to discover
the 6-speed protruding gears. The door was machined to accept
the gears and the 5-speed door was not. I was stuck. I contacted
Muller in Germany for a 6-speed replacement door. No answer. I
called JIMS and ordered the kicker they distribute for the 6-
speed. It never arrived, so I called Custom Chrome. If I could
order a 5-speed quick, I could use the Muller system. They
responded and in three days I had a Rev Tech Replacement
complete with kicker and 23-tooth chain sprocket. I yanked the
6-speed and began to install the Rev Tech 5-speed in 4-speed
case with a five-year or 50,000 mile warranty.
Here's the RevTech 5-speed trans installed.
At this point I should have replaced the rear 51-tooth
sprocket with a 48 or perhaps a 46, but we’ll see. I removed the
kicker cover and installed the clutch cable once more, sealed the
tranny and filled it with 24 ounces of fluid.
Here’s the massive JIMS socket.
I pulled the massive, left-handed, mainshaft sprocket nut
with a JIMS special tool and flopped it around backwards to
afford me the clearance I needed for the RevTech chain to pass
the 180 Avon tire. I locked it down with the JIMS tool and an
Allen setscrew and red Loctite. She was good to go.
This sucker is left-handed, don’t forget.
Next, I needed to set up the BDL 300 belt drive system and
the Compu-Fire Charging system. I slipped in the Stator, then
the small tapered washer, followed by the Compu-Fire Rotor. It’s
pasted right on the rotor not to smack it with any hammers. You
might knock one of the magnets loose.
According to the rules sometimes the offset pulley mount
doesn’t need the massive flat washer/spacer for proper
alignment. But the first move includes installing the inner
primary with the engine and tranny loose. I used never-cease on
the threads of the transmission and tranny Allens to prevent
damage to the threads. Take it back—first I had to remove the
inner primary studs from the transmission. They were tight as
hell and I used Yield and heat to set them free. Then I positioned
the engine and the Trans with the primary.
I ran into problems. Nothing wanted to line up. I called a
couple of buddies for guidance. I held the engine where it was
with a shim under the front motor mount. Then I bolted the
primary to the engine and trans. The front of the tranny raised
almost .100. I started looking for shims. Bob from BDL told me
the code was to shim the tranny plate and not the tranny, so I
went to work. It wasn’t a problem to scour around for the right
thickness washers. Soon the transmission was aligned, the
primary fit easily and there was no drag on the transmission
mainshaft.
Next, I needed to check the pulley alignment. I installed the
pulley using the insert then the pulley and Allens. Since I would
be removing and replacing the parts, I didn’t drive the alignment
pins into the insert from the rear just yet. I discovered another
glitch. I needed some washers or shims behind the engine pulley
for alignment. I also discovered that the mainshaft nut wasn’t
bottoming out, so the rotor flopped around. That wasn’t right.
I’ve installed a dozen BDL systems without major alignment
problems. It takes patience, but once it’s correct, she will last
and last. This is a tapered shaft transmission and once it’s
installed it doesn’t slip off without a JIMS transmission hub
puller tool.
I used this straight chunk of T-iron. I held it against one
pulley and checked spacing with the other and feeler gauges.
I>
With the pulley and the clutch in place you can test
alignment a couple of ways. I used a cast T-Bar across the faces
of the pulleys. They need to be exact, which means shims
behind the engine pulley.
I made a mad dash to Walkers Machine and bought all the
goddamn shims he had. The massive washer that comes with
the rotor was only .035 too large. The next item was the inset in
the engine shaft nut. I had to machine it to slip over the
protruding shaft. This is also an area that takes some running
and retesting to make sure it doesn’t seat and settle in, out of
alignment. It’s easy to spot a problem. You’ll notice rubber dust
around the pulley where it’s riding against the lip.
Remember that the clutch nut is also left-handed. Then the
clutch slips into place and with some tugs and working the belt
gently, it goes on. If not use two chunks of wood a large bolt
and a socket to gently push the pulleys apart. Once it’s run for a
while it will be much easier to remove and replace.
Here's the primary after the Sturgis blast of 1600 miles, with
a 5-Ball in
place.
Okay, so I installed the tank, with the Spyke petcock and
stripped the spigot threads. It hung for most of the ride. We’ll
cover the tank more in the ride saga, so hold on. The seat was
also a challenge. I slipped off, so I changed the seat, to one with
a lip, then changed it back an added taller springs. That worked.
With the primary aligned I still used never-cease on the
primary threads because I knew that I would remove the inner
primary once more.

catalog.
Here’s my second sordid glitch
B>
Hang on for this one. I needed to find a place for a
toggle
switch/ignition switch. I also had this massive aluminum starter
motor boss on the inner primary that was going to waste. So I
drilled out the starter shaft and installed a marine ignition
switch. I glued it in place with a two stage epoxy then drowned it
with liquid electrical tape, two coats. It seemed perfect except
that the key sang in the wind only 1 inch above the peeling
primary belt. No key rings or dice.
On the inside of the primary I made a brass strap that ran
from one starter mounting hole to the other, holding two circuit
breakers. One was a 15 amp for the lights and a 30 amp for the
ignition. This became a very tight electrical area, dangerously
close to the whirling CCI O-ring chain. As it turned out the
circuit breakers were a hair or two from the coils. Cozy. I made a
couple of wires long enough so that I could remove the primary
and set it next to the bike to work on wiring issues.
The next thing I knew, under initial testing, the whipping
chain chipped at the aluminum, dangerously close to the
electrical. Larry Settle, of Settle MC Works loaned me a chunk of
tephlon, which I carved and made a buffer, which worked
perfectly to protect the chain from nearing hot wires.
Then came the Eye Candy Custom Cycles ’59 Cadillac
taillight. They also make an old Ford style light, which I prefer,
but I felt the need for side visibility, especially on the right. The
mounting called for the primary once more to hold the taillight/
brake light. Finding the proper location was a chore. It either
rode too close to the chain or the mounting called for screws
through the frame or into the wiring loom. I monkeyed with it
for hours and finally designed a tough mounting system that
might survive. All went well, but the frame rail still blocks the
light and I might move it outbound.
Here’s the taillight to primary bracket.
This is a life saver heat gun when it comes to wiring, but be
careful with this bastard. The tip is hot whenever you set it
down. It doesn’t stand on its own well.
Here’s the taillight and license plate bracket in place.
I ran the thin sparkplug wires through the frame in shrink
tubing, wired the coil and the Joker machine brake switch and
headlight through the hole in the frame too close to the fork
stop. Even on a simple chopper an idiot can find his way into
trouble.
Finally I mounted the stylish Aeromach mirror on the left
bar only. It came with all the hardware needed and never gave
me a problem. I know I’m missing a link or two, maybe a
necessary credit. Don’t hesitate to drop me a line if you need a
question answered. You can reach me daily at Your Shots or
drop a line to Bandit@Bikernet.com.
For some reason the taillight lense didn’t come
with fasteners. If figured if I glued some nuts on the inside,
they’d vibrate loose, and I could never change a bulb. Since
every chopper needs bailing wire, that’s what I used.
Over the next couple of days I will attempt to complete the
first saga of the ride to Sturgis. I hope to launch it on Friday. In
it I will dig into the problems I encountered, mistakes I made
and how I fixed them. Hang On. But beyond the glitches, actually
the wiring worked out fine, but I should wire in a kill switch. The
bike rode well, comfortable for a rigid, started without major
hassle and ran all the way to Deadwood. I can’t complain.
How's this for the first riding shot?
