New Cad-Cam designs
produce a
highly engineered efficient & economical product.
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."
