Good To Know

Q: What else should I replace during a top end rebuild? A: It is wise to inspect the valves, cam chain, and gaskets while the cylinder is off. Replacing worn seals and gaskets helps prevent leaks after assembly.

Q: Does this kit require machining before installation? A: No machining is typically needed since the cylinder and piston come matched. Check piston-to-cylinder clearance and ring end gap before final assembly.

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