I have an 03 ltz400, rode it for a week after buying it ran fine. put it away one night, went out to ride it 3 days later and it bouncing off the reverse rev limiter in all forward gears. Bought a used "performance" cdi same exact thing no matter where i set the rev limit too on the new box. read up how to disable the reverse rev limiter, checked it many times did continuity checks everything looks and tests perfect. still no change. check timing, spot on. checked plug perfect with nice blue spark. check continuitys on the gear switch even though i had disabled the reverse rev limiter but it passed so switch is all good. i have read through many threads and tried everything i have been able to find and still has the same issue that just magically happened over sitting in a shed for 3 days. Any ideas or am i totally screwed.
