designed to provide equal life and better performance than the OEM engines
they replace. We have combined proven OEM parts with our own high quality
components replacing the weaker items of the OEM engines, insuring a
problem free long engine life.
We think that these engines are
the smoothest V-Twin engines available in the industry due to our
exclusive dynamic balancing methods and we back them up with a 12/12
warranty. Assembled by professionals, all engines come pre-run and are
complete less charging systems

Accomplished Engine
Designer and Racing Engineer Ken
Francis states:
"The big
difference between our product now and what we had in the past is that we
do have a much lighter reciprocating weight in the engines that don't
shake that much. They are in fact, pretty smooth."
"These engines are VERY AFFORDABLE by efficient
design & engineering."
