Description
This is a brand new race ported 27.2cc 4 bolt upgrade kit. To start we machined the combustion chamber for the longer stroke without stacking base gasket. This kit comes with a hand ported 34mm cylinder cut for a 2mm stroker, 2mm stuffed crank shaft, piston, ring, wrist pin, c-clips, spark plug, and base gasket. The following machining and port work has been done: Machine combustion chamber for 2mm stroke, Resurface all ports for better gas/air mixture, Modify transfer ports for better flow, Raise/enlarge/reshape exhaust port, Rebevel all porting and factory bevels to prevent damage to the piston
