Specs At A Glance

Good To Know

Q: Does this piston need cylinder machining? A: A .040 oversize piston requires the cylinder to be bored and honed to the matching 67mm clearance. Confirm with your machine shop before ordering.

Q: Can I install one oversize piston with the other cylinders stock? A: Mixing bore sizes is not advised, since compression and balance can vary across cylinders. Rebuild all pistons to the same specification.

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