Good To Know

Q: Does this kit include a new cylinder? A: No, this is a top end repair kit consisting of piston, rings, gaskets, and hardware; the cylinder must be bored separately to the 67.5mm size.

Q: Will this work with stock carburetion? A: Typically yes, but a proper jetting adjustment is recommended to take advantage of the increased compression and prevent detonation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
