My friends yfz450 just got rebuilt and it ran just fine. He put an HMF pipe on then jetted it and it rann fine. Anyways one day we go to ride and it wont fire, itll just crank and crank. His battery is about junk cuz itll die after so long, but it was on a charger and it just wouldnt fire. Itll eventually shoot a little flame out of the exhaust.

He also has a kicker on it but doesnt use it because he hasnt cut his fenders yet

cdi pulg came undone. did the same exact thing to me today. take the cdi off and put it back on nice and tight should be good to go.
