Good To Know

Q: Does this piston fit a stock cylinder without machining? A: No, a .080 overbore piston requires the cylinder to be bored and honed to the matching 97.00mm size before installation.

Q: Can I install this piston kit myself? A: Installation requires engine teardown and precise cylinder work, so professional machining and assembly are recommended for best results.

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