Good To Know

Q: Will this kit work with a cylinder that has been honed or replated? A: This standard bore piston kit is designed for a cylinder within factory specifications; if your cylinder has been overbored, a different size will be required.

Q: What is the difference between Size A and Size B? A: Size B is a slightly tighter clearance piston often used when the cylinder is at the tighter end of the tolerance range; always measure your bore to confirm.

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