Good To Know

Q: How many O-rings should I order? A: This listing is for one O-ring, so order the number your engine needs based on how many power valves you are servicing. Check how many valves your RFI 800 engine has before ordering.

Q: Should I replace this during a power valve rebuild? A: Yes, it is a good practice to renew the O-ring whenever the valve is removed. A worn O-ring can leak and cause inconsistent exhaust timing.

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