yamahatzr50declan Posted January 4, 2012 Share Posted January 4, 2012 Hi there, i am new to the forum, and i have a problem with my yamaha tzr50 2004. My bike has been running badly ever since i perchaced it and i have been trying to track down the problem for weeks in the end i took of the flywheel cover and i cheked the timing with a flash light and it was stuck at 24 degrees. I think this is too far advanced and that it is meant to change when the bike is revved up. Aslo the rev counter jumps around all the time so i think that it is the cdi that is broken. Also the stator is 12v and has 12 coils instead of the usual 6 on most of the am6 engines. could anyone suggest what to do? many thanks Declan Link to comment Share on other sites More sharing options...

Moderator Airhead Posted January 4, 2012 Moderator Share Posted January 4, 2012 24 degrees @2000rpm is correct it should start to reduce at 4000rpm to a final 20 degrees @ 12000 rpm yeah read my signature line Link to comment Share on other sites More sharing options...
