Good To Know

Q: Can this piston kit be used with a cylinder that has been honed? A: This is a standard bore piston; it should be installed in a cylinder that is within factory specifications. If the cylinder is worn, boring to the next oversize may be necessary.

Q: Does the kit come with gaskets? A: Gaskets are not included in this piston kit; separate gasket sets are required for a complete top-end overhaul.

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