FAQ

My piston oil ring doesn't fit. What should I do?

The original oil rings were 3/32" thin. We've not found a manufacturer that can produce a 3/32" thick oil ring. However, we have plenty of 1/8" thick rings in stock, and most manufacturers can make a 1/8" oil ring. The solution is to machine the oil groove in the piston to match the oil ring, leaving a 0.0005-0.001" clearance for the ring. To machine the groove, a 6-jaw chuck on a lathe can hold the piston steady. Soft jaws are preferable.
Do you have a good set of heads?

Maybe. The heads in stock are used and generally have damage to the fins, especially near the spark plug. This is cosmetic damage and a good welder can repair them. Heating the fins up to about 600F gives them enough pliability to bend fins back. Some heads, however, are cracked where the rocker box meets the intake. These require more extensive repair. I clean and check all heads for this crack before selling them. As of May 2024, I have no good set of Warrior heads.
