Good To Know

Q: Why choose a .040 oversize piston instead of stock? A: An oversize piston is used when the cylinder has been bored to clean up wear or scoring, restoring a true bore surface for a proper ring seal.

Q: Does this kit include rings, pin, and clips? A: Piston kits of this type are typically supplied as a complete assembly, so confirm the exact contents of the listing before ordering for your XL700 rebuild.

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