A Ducati Restoration - Well Maybe
! |
It was early July 1983. Pittsburgh was
having the usual heat wave. My auto restoration shop was in-between jobs. My
long-time racing friend was answering the phone and painting his mom's car, so
Phyllis and I left for the Bahamas. We were staying at the newly opened Coral
World resort near Nassau while our Bahamian attorney's wife flew to Eleuthera
to surreptitiously empty the joint bank account we shared with our negligent
'partner' in the retail ice business. Our partner was not fairly dividing all
the profits from a commercial ice machine that we had imported and installed in
his hotel/bar on this very skinny and very long out-island. All this was not in
strict accordance with Bahamian statutes, mind you, but if you can't trust a
criminal, whom can you trust? While our proxy was busy cashing-out at the
Governor's Harbor branch of Barclay's Bank, we were enjoying our bayside
room-with-a-view and private pool (paying the off-season 'travel-agent' rate),
driving intoxicated on the left side of the roads, and generally stuffing
ourselves on prawns and conch in Nassau. It was not exactly a nerve racking
wait for our money, and the international phone service was such that my
in-laws couldn't call us twice a day to make sure we hadn't drowned or been
murdered. Neither could my racing friend.
John's birthday and mine are
a day apart, July 8 for me, 7 for him. We had reminisced for years now over all
the fun we had in the early '60s with a very trick Goldstar he had built, and I
had piloted and mostly paid for. Boy, if we could only do it again with what we
know now! Well when Phyl' and I got home, John invited us over to his place to
see the birthday present he got himself, and not incidentally, the one he got
for me. This would be a Norton Dominator 99 (don't worry, he only needed it for
the frame), and for me, a Ducati 750 twin (don't worry, it'll make a great
roadracer). It was too good a deal, that had to be negotiated in a very timely
manner, cash, of course, so he simply borrowed a few thou, in my name, from my
shop landlord! I was, ah, quite surprised.
|
A 1974 750GT,
plenty of potential, and John already had Syd Tunstall's latest catalog with
all the goodies I might need. He also had Cosmopolitan's catalog opened to all
the goodies he might need. It wasn't just an offer I couldn't refuse; it was a
done deal. But wait, there's more! I was shown fresh sketches for all the
bodywork he envisioned for his 'new' Norton-framed Goldstar, including a
half-fairing that would also look nice on my 'new' Duc. In for a dime
, in
for how much? Well, the Third World ice monopoly had been good to me, and it
was looking to be good for Syd as well. John had found new purpose in his life,
and, oh by the way, another new catalog: Aircraft Spruce & Specialty,
purveyors of Fiberglas, Kevlar and carbon-fiber. In for how much
? Never
mind! He set about crafting masters, then molds, swapping Norton parts for
Goldstar goodies, and trading up, down and sideways for big brakes. All the
time, encouraging me to do something, anything, with the GT:

I got as far as
mocking-up a bike with Syd's glass and Cosmo's Grimeca 4LS when tragedy struck.
John's fragile heart left him, and he died on the eve of my birthday. I was so
overwhelmed that it would be five years before I could return to either the
Featherbed Goldstar or the café Duc., both works-of-love in progress.
When I finally assembled all the parts I could find for the F/Gs, the magic
began to take shape:
The Grimeca had been up-traded to front and rear
Yamaha TZs, the RoadHolders had turned into Cerianis, the frame had a trick
swing arm and exhaust, and all the bodywork was finished in Kevlar and carbon
(shh!).
|
I took another
look at the Duc and the not so small pile of parts that might fit on it. This
would have to be resurrected as a roadracer, not just a café 'cutie'. I
began by doing what I do best: take things apart. I stripped everything to the
bare frame, cleaned and examined all the parts, and continued with what I like
most: paint! Starting with a quart of 'Farina red' (Isn't farina white? No,
it's a man not a cereal, you young parts-person.), I painted the frame and
began fitting the body parts first. Now for the real fun:
|
John's choice of a
GT model seemed to be very wise. The mileage was low, only 8512, and mechanical
wear was almost non-existent. No visible wear on either of the sprockets, and
the chain, fully extended, would only bend about two inches. The sides of the
carb slides were barely polished. The only engine covers that had ever been
removed were for the tappets. The valve lashes were in adjustment, and looking
down the ports, the valve heads looked new. The previous owner (only one) did
not believe in using a front brake, ever, and the rear shoes were only
moderately worn, with the drum looking perfect. The ignition points had never
been adjusted and the gaps were still in spec. Much better than I had a right
to expect!
I re-laced both wheels for a start. The rims needed a little
buffing, and I wanted all the spokes to be at the same tension. I like to do
this by plucking them for equal pitch while the wheel is being trued. Next came
the Comp-Ks.
Trial fits for all the bodywork was next and the mounting
points were easily located (thank you, Syd). I wet-sanded all the gel coats,
which were free of imperfection (thank you again, Syd), and loaded up the spray
gun. I must say that watching freshly applied, catalyzed enamel gloss-over is
almost as satisfying as
, well, you know. Once the paint had a few days to
harden, the end product took shape:
|
Not too shabby!
A cute feature about reconstructing a bike for racing is that one only
puts back things that are involved in getting down the road and coming to a
stop. Minimalism is the order of the day. Parts that are never installed are
parts that never fail! Turn signals? We don't think so. One headlight will do
the job, and since right-handers predominate on a track, a left-hand offset
provides the most height on most corners.

Oh, that beautiful
fairing.
It was John's philosophy that streamlining must control
turbulence, direct cooling air and fit the rider like a 'suit of clothes'. The
rear edges of the screen are shaped to fit flush with the tops of my shoulders
when my chin is on the tank. The bottom of the fairing is reverse curved just
above the tire and extends from the outsides to the top frame tubes in order to
keep air flowing as smoothly as possible past the motor. Together with the
bottom of the tank, a belly pan of sorts is formed. As a general principle, all
the glasswork was insulated with rubber strips or grommets from any metal and
attached using nylon screws and nylon stop-nuts. Nobody likes stress. Ducati
used elastic stop-nuts everywhere they could, and this practice was continued
with any new parts. My local hardware store had recently added a full line of
metric fasteners that included allen cap screws and stop-nuts in stainless, no
less, steel at very reasonable prices. This used to be a serious problem, but
not no more.
The little touches:
|
The curvy Italian
gas cap is replaced (sorry, Syd) with an FAA approved, flush-mount that's a lot
easier on chins.
The rear sets are
mounted in dead-soft aluminum and folding pegs are proof against accidental
grounding (don't ask). Rubberized-cork, thick gasket material lines the battery
tray. The folding kick-start lever is hard to find!
Pull out the
aircraft, push-button 'T' handle, and the seat slides off to reveal the
regulator and relay/fuse tray. The nominal baffle in the mega improves torque
(thanks, NCR) and keeps everything street legal (chuckle).

The front brake at
260mm is the largest drum set-up ever built. Yes, discs were used at the time,
but they were heavier and complicated. These babies are so frightening; you can
win a race when you show up in the pits. They are simple, easy to inspect
(giant holes everywhere) and never suffered a hydraulic failure. The air horns
are lighter than the stock (ugly) units and have enough power to be heard over
the exhaust note (heh-heh). Besides, they keep it legal. The clip-ons are the
adjustable-drop style (easy on the wrists) and the surgical-rubber grips have
no peer.
The whole of the machine compares very exactly to Paul Smart's
historic Imola winner. The (wide) frame, (leading axle) forks and shocks are
identical. Not so for the S and SS model. The tank is larger, but hey. Overall
weight is a trim 320lbs. The GT motor is 'torque city'; durability is legend!
A few words on the electrics: I am using the original key switch to
operate an automotive main power relay (RadioShack). This avoids any current or
voltage drops at the coils. I carefully grafted a microswitch (RadioShack
again) into a horn button on the throttle housing. A switch under the
'electrics' tray allows it to either actuate the horn relay or de-activate the
main power relay, i.e. a kill button. For the wiring, I chose a four-wire
harness with a molded connector designed for trailer lights. The conductors are
sturdy and color-coded. I like to use silver-tin for solder, and I never strip
the wires with a tool. Even the smallest nick is an invitation to fracture! An
aftermarket turn signal switch on the left bar operates the headlight. The
center-off position kills the light and the right/left positions become the
hi/lo positions (easy to flip with a thumb).
It's been said that 'God
lives in the details'. I may have left a few out of this story, and I hope He
doesn't take any offense. Building a racer is more satisfying to me than say,
trying to match original paint colors from faded magazine pictures to impress
some concours judge. Engineered solutions can be elegant in their simplicity,
of course all problems are trivial once they're solved, but I would never call
a bevel-head Ducati simple. Trying to match the quality of the original design
is all the challenge, but matching the quality of the original finish is not.
For that reason alone, I made no attempt to (over)polish any of the aluminum.
Besides, there would be nothing left for the next owner to do over the winter.
I have yet to start the bike, mostly because the temptation to
terrorize my neighborhood could be impossible to overcome. Besides, now that
I'm back in practice, the Featherbed Goldstar is begging for completion. There
may be some issue with club regulations, and the Langlitz people will have to
let-out my old suit, but once you've smelled the castor
what can I say?
