I'm listing this add for a friend; I've been helping him work on it.
He has an 04' yfz, bone stock except for exhaust and air filter motor wise; just the other day he was riding through the field draggin against someone else. He went through 1st 2nd 3rd turing it hard, it backfired and cut off. All it will do now is spin over.
I thought maybe he sheared the flywheel key. I pulled the flywheel off and the key is fine, also the timing is perfect. No slack in timing chain. I thought maybe he floated the valves and bent them from turning it hard but its making good compression.
His plug is firing, atleast when we pull it out. But, when you pull the plug out it smells strong with gas after it has been spun over.
I'm kinda clueless, it backfires a little turing it over though... Maybe its got some wiring issues or could be the rev box, i honeslty don't know..
