Good To Know

Q: Can I install this .080 piston in a stock cylinder? A: No, the cylinder must be bored and honed to match the .080 oversize before the piston is fitted.

Q: Does this kit include the piston rings? A: This set is listed as a piston and gasket kit, so check the listing photos to confirm ring inclusion before ordering.

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