Good To Know

Q: Will this piston fit a stock cylinder? A: No, it is a .060 oversize piston and requires the cylinder to be bored to 82.50 mm first. Installing it in a stock bore will not work.

Q: Can I mix this with other oversize pistons in one engine? A: Each cylinder should be bored to match its own piston size. Confirm your machine and serial number 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.
