ABSTRACT:
An assembly modification of an existing two-stroke single cylinder 43 CC to 52 CC combustion engine. The assembly substantially increases the horsepower of the stock two-stroke engines. The modifications include using a reed valve kit which is modified to connect to the threaded carburetor connection bolt holes on the outside of the engine casing at the intake port. A drilled excavation in the interior face of the engine cylinder to provide for an additional transfer port at the location of the fuel/air intake port is also provided. The additional transfer port has a roof with varying angles of inflection depending on the performance characteristics desired during operation of the combustion engine. The reed valve kit also provides additional configurations for larger or smaller carburetors located at the intake port of the reed valve block. The piston skirt is modified for an additional opening at the intake port for providing fuel air mixture into the crank case for additional volume intake.
