Good To Know

Q: Do I need to re-use my old wrist pin? A: No, a new wrist pin is included in this kit for optimal fit and longevity.

Q: Can this kit be used with a stock cylinder? A: The .040 over bore requires the cylinder to be bored to 66mm, so it is not a direct fit for a stock bore.

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