Good To Know

Q: Do I need to hone the cylinder before installing this kit? A: Yes, honing the cylinder is recommended to ensure proper ring seating and sealing. Check bore dimensions against the piston before assembly.

Q: Is this kit sold as a single piston or a set? A: Confirm the quantity in the listing before ordering, since some kits include a single piston and others cover both cylinders. Match the kit to your engine configuration.
