ABSTRACT:
The invention provides a bypass around virtually the entire periphery of a piston in a two cycle engine without substantially increasing costs or obsoleting production tooling. This is done by reshaping a cavity formed inside an engine casting to enlarge the crank case opening and to provide three oppositely displaced bypasses. The fourth side of the piston is open to the exhaust port. Therefore, virtually the entire perimeter of the piston is bypassed to greatly increase power by improved breathing.
