bob-c Posted February 8, 2010 Share Posted February 8, 2010 when power valve kicks in bike starts to stutter, can the power valve get stuck? how do you go about fixing it? Hi, the powervalve can need cleaning to remove carbon etc., here is a useful set of pics , watch out which way you replace the valve , they can go in 180 degrees out . This site also has manuals http://www.dtr125.net/videohtml/ypvs/powervalve.htm Bob-C Link to comment Share on other sites More sharing options...
