2002 YZ125 Power Valves Sticking

The only feasible idea that I have is to replace the springs. Will post the outcome.

If the jug was just back from re-plate, make sure you wash it real good with soap and water. I use a little brush and clean all ports to make sure no debris or burrs are in the PV port. After the wash, WD-40 bath and blow it out with air. Lube up the system with a little 2T oil and check to make sure the PV is moving free. Assemble and your good. If it sticky, look inside the PV slide to make sure it's free and clear.

Great find!
