Good To Know

Q: Does this kit include a wrist pin and circlips? A: Yes, the Namura piston kit comes with a wrist pin and circlips; you will need to reuse or replace your existing bearing according to service intervals.

Q: Can I install this without machining the cylinder? A: Since this is a .020 over bore piston, the cylinder must be bored and honed to match the 47.44mm diameter by a qualified shop.
