PioneerX Posted March 3, 2008 Share Posted March 3, 2008 chack the basics first. 1. it turns over 2. there is a spark 3. there is fuel Once you know you have yes/no answers to the basics then the actualy fault tends to be easier to find. Link to comment Share on other sites More sharing options...

If all these check out then it is your CDI/Ignition module. If at all possible try and borrow and swap any parts that you think might be duff from a running /donar bike before spending lots of money on parts like coils,pick ups and ignition module's hope this helps regards Billa65t Link to comment Share on other sites More sharing options...
