Specs At A Glance

Good To Know

Q: Can I install a .080 over piston in a stock cylinder? A: An overbore piston requires the cylinder to be bored and honed to the matching size before assembly. Have the machine work done by a shop that can confirm the finished bore clearance.

Q: Should rings and gaskets be replaced at the same time? A: A piston kit is normally fitted with new rings, wrist pin, and top end gaskets for a reliable seal. Verify that all supplied parts match your rebuild requirements before installation.

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