Good To Know

Q: Does this kit include wrist pin or piston rings? A: This is a gasket kit only, it does not include the piston or rings. The gaskets are specifically designed for a .040 over bore piston.

Q: Is this compatible with the stock cylinder? A: When using a .040 over bore piston, the cylinder must be bored to match the 78.7mm piston size; this gasket kit fits that application.

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