.What
pushed me into rebuilding and detailing carbs was not the desire to "go
into the business" but pretty much the opposite. Most of the cycle carb
rebuilders quoted me prices of $275 to as much as $450 to rebuild a set
of carbs. At those prices I could almost buy a new set of FCRs or one of
the dual carb setups. As far as I was concerned this was not an option
as I was not building a Jesse James or OCC rich bitch chopper.

I have been rebuilding carbs
for others now going on 7 years and tackled some pretty nasty messes. Most
of the time the worst are those that have been on a bike left sitting and
the owner did not have the presence of mind to drain the bowls before parking
it. The worst are those that are left outside in this condition, worse
yet with the throats exposed to the elements. These can be salvaged but
there are times when a second set of parts carbs is needed as donors for
one good rack.
.
I use a number of methods
to thoroughly clean carbs. I use two dips, one meant for soaking to loosen
petroleum deposits and another more agressive dip to remove stubborn grease
and road grime. I usually try to avoid the more agressive dip if possible
just to be on the safe side. After dipping the carb castings are flushed
with near boiling water and all the fuel and air passages blown clear.
On a few occasions it has taken a second dip and flush to clear all the
passages. This is probably the main thing missed with the usual "garage"
cleaning. Quite often deposits remain in the fuel and air passages and
brass components and have a direct impact on the performance of the carbs.
These passages are precision bored and any restriction or constriction
of the passages alters the dynamics and ultimately the performance.
.
Rust removal is another
process the carbs go through depending on what the customer elects to have
done. Sometimes it is almost impossible to remove all the rust, but most
often if the carbs have not been left to rust and corrode outside the rust
can be removed fairly easily. Some components are plated and unfortunately
when these rust the steel components must be cleaned to the base metal
to remove the rust, oxidation, and corrosion. I am able to simply clean
carbs as is (no kits or detailing) up to complete disassebly and detailing
including fuel resistant high heat engine paint on the outsides and polishing
of non-coated aluminum and steel. In the future I hope to offer powdercoating
but this is yet a ways off. Regardless if just a cleaning or complete detailing
the idle adjustments are set to factory starting specs, float levels set
to correct height, and the carbs are bench synchronized before they leave.
Rejetting is easily done while they are here to match custom applications.
