Good To Know

Q: Will this piston kit work with a bored cylinder? A: This is a standard bore kit at 66.5mm, so it is intended for cylinders that have not been overbored or have minimal wear.

Q: Do I need to replace gaskets separately? A: Yes, this kit includes pistons and rings but does not include gaskets, so a separate top-end gasket set is recommended for a complete rebuild.

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