dtr_125 Posted March 2, 2009 Share Posted March 2, 2009 Right got the bike stripped down. Its a yamaha dtr125 1994 model with powervalve. but wont fire up, its got fuel in and theres a spark but heres the problem. Theres a spark when the ignition is not on but stops when ignition is live. So ignitions on and all lights, temp guage and powervalve works but theres no spark, then cut the ignition and theres a spark and it fires up for afew secs then dies again. Had this problem before it got stolen where the spark would sometimes stop and to start it you had to flick the ignition on while kicking it over. Could this be something simple ignition coil? or would a whole rewiring be needed? Also the nuetral light stopped working jsut before it was stolen which im sure is something inside the generator or gearbox that is causing this? That can be solved later but atm i need help on the sparking issue to get it running propely?? Link to comment Share on other sites More sharing options...

Sounds to me like a possible faulty ignition switch, disconnect the switch and try again with it disconnected, if your bike is a magneto ignition system the sparks should work with it disconnected Link to comment Share on other sites More sharing options...
