Good To Know

Q: Does this kit include a cylinder? A: No, only the piston, rings, and gaskets are included; the cylinder must be bored to match the oversize piston.

Q: Can I use this on a stock cylinder? A: The cylinder must be bored to 69.25mm to accommodate the oversize piston, so a stock cylinder will not work without machining.

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