Good To Know

Q: Does this kit work in a standard bore cylinder? A: No, this is a .060 oversize piston that requires the cylinder to be bored and honed to 82.50 mm first. Fitting it to a standard bore will not work.

Q: Is a single piston or a pair included? A: Confirm the quantity on the listing before ordering, since piston kits for this engine are often listed individually. Verify you have the matching count for your rebuild.

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