ABSTRACT:
In order to increase the displacement of a motorcycle engine, the existing cylinder block of the engine is dismounted from its crankcase, and the existing piston is dismounted from its connecting rod. Then, a new piston having a greater diameter than the dismounted existing piston is mounted on the connecting rod, and a new cylinder block having a greater bore diameter than the existing dismounted cylinder block is connected to the crankcase while sliding the new large-diameter piston along the inner wall of the bore of the new cylinder block. The new cylinder block has a bottom end that is located above the top end of the crankcase when mounted on the crankcase. The new piston is short enough not to be inserted into the crankcase when moved to the bottom dead center. This eliminates the need to disassemble the crankcase or any parts in the crankcase. It is thus possible to easily increase the engine displacement.
