Re: The Fitch Fuel Catalyst
As Mark and Ralph know, I own and race several vintage and antique racing bikes and am
a member of the Vincent Owner’s Club. Many of my bikes have been raced in vintage and
“TT” races at tracks all over North America and Europe including Shubenacadie, Nova
Scotia and Daytona, Florida.
I was introduced to the Fitch Fuel Catalyst after a visit to Ralph’s shop and decided to try
it in the Rudge and the Vincent Single. After the installation, there was a noticeable
improvement in the transition from pilot to mid-range throttle positions. I really noticed
the difference at Shubenacadie because it is a road-race track which has very few places
for the bike to operate wide-open yet the performance was smoother and more
predictable.
Both machines are running cleaner as well. The Rudge has externally grease-lubricated
valve gear. I did not expect to see much of a difference in the color of the exhaust pipe
because of the soot and residue from the grease, however the pipes on the Rudge and the
megaphone of the Vincent are noticeably brighter which is similar to the leaded fuels we
used to use. The spark plugs are also cleaner; a light brown.
It seems the combustion is cleaner burning and takes place at a higher temperature as the
megaphone on the Vincent is starting to turn blue. This is something that had never
happened prior to the installation of the Fitch. The Rudge sounds much crisper which is
an indication of better combustion. I have not done any jetting or carb alterations to
cause these changes.
I do believe this product is working, so much so that I have purchased an additional unit
for the Vincent Sidecar Racer.
Thanks again
