Good To Know

Q: Does this kit include piston rings? A: Yes, the kit includes piston rings, wrist pin, and circlips.

Q: Is this kit compatible with the stock cylinder? A: This .020 over bore piston requires the cylinder to be bored to 90.5mm, so it is not a direct replacement for a stock bore cylinder.

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