Specs At A Glance

Good To Know

Q: How many O-rings should I order? A: Each order includes one O-ring, so confirm how many power valves your 951 engine uses before ordering. Many riders replace the pair at the same time.

Q: Should I replace other gaskets while I am in there? A: Power valve jobs often include fresh gaskets and seals around the assembly, since removing the valve disturbs the surrounding pieces. Inspect everything once the valve is out.

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