Lars01 Posted August 10, 2018 Share Posted August 10, 2018 Hey, the ypvs is not working properly on my dtr.. When i start the ignition the pulley moves the valve as normal. Then i start the bike and the ypvs seems fine. The pulley is moving but suddenly it just stops?? It can stop at any time, after the first rev or after a short trip. I have tried to look after people having the same problem but it seems like people ypvs do not move at all or it works. I have removed the power valve, cleaned it so tjat it moves freely, i have adjusted the pulley cables (many times!) and i have opened the servo too see if everything is good. I have hear it can be the pv controller or the cdi, but these are expensive parts so is there a way to check if mine works or something? Thanks Link to comment Share on other sites More sharing options...
finnerz89 Posted August 11, 2018 Share Posted August 11, 2018 Seeing this more regularly I'm afraid, most likely your CDI. Only way to check is try another unfortunatelySent from my SM-G950F using Tapatalk Link to comment Share on other sites More sharing options...
