can't find any search info on cleaning powervalves

Easy as pie take off your pipe, two bolts hold the valves in, i take the cover off the servo motor and turn the motor back to losen the cables. There is a allen head screw that holds the valve to the cable undo it be sure you notice which way and what side the valve came out of. i use a razor blade to clean the valve off. Put some oil on the valve and reverse the way ya took it out to put it back. The gaskets should still be good i havent had to replace one yet. Make sure to turn the servo motor forward to tighten the cables up. I put a dab of silicone on the cable ends so the cables dont fall off the servo motor.

You don't need new gaskets unless you bend them real bad. To get to the old forum go to general snowmobiling in the new forum and there is a link to the old forum. hope this helps
