Good To Know

Q: Is this piston kit compatible with a standard bore cylinder? A: No, this is a .020 oversize kit intended for cylinders that have been bored to that size. Always have your cylinder measured before purchasing.

Q: Does the kit include a cylinder gasket? A: The kit includes piston rings, wrist pin, and circlips but does not include a head gasket or base gasket; those must be ordered separately.
