Good To Know

Q: Does this piston kit require boring the cylinder? A: A .040 oversize piston is sized for a cylinder already bored or honed to match, so measure your bore before ordering.

Q: What else should I replace during a top-end rebuild? A: Pair this kit with a fresh gasket set and check the cylinder and valve train while the top end is apart.

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