I followed the recommended settings for a single pipe & clutch kit and came up way too fat, had the left cylinder hogged up all day. After cleaning excess gas out of everyplace imaginable I did some carb work to lean it back some. Aside from running it in the garage I haven't gotten to ride yet. I was wondering how bad the power valves could have gotten hogged up in the course of that shitty afternoon. I pulled the cover off the servo, disconnected each cable and was able to move each PV freely - a good sign. The PV has four screws around the outside and two on the smaller plate where the cable goes. Never had one apart and dont need surprised or worse yet screw it up. If I were to clean them can anyone explain the proper way to do it.? Or do I leave them alone all together.?
