We build our big bore kits and cranks to much tighter tolerarances and with higher quality materials than the factory parts. This new piston/cylinder kit will be a solid platform for massive power.
Huge displacement increase means huge power increase. Original engine serial numbers are retained. Powder coat finish match factory finish, giving the bike a "sleeper" advantage. 045 MLS (multi-layered steel) head gaskets.Includes 131 Cam Cover Badge. Must be used with our stroker flywheels to achieve 131 displacement.
