Hi

This thread doesn't really have much fix-it traffic.
I'd be tempted to try the quad or other bike sections.

Do you have juice TO the coil?

[Mr.Atc]

no i dont have anything to the coil the reason im screwed is i cant find a wiring diagram anywhere that doesnt want me to pay for it but im gona have to i guess

problem=yamaha

check stators, CDIs, Any type of coil.
even just checking them has proved to not help in my experience. sadly, its no better then to have spare parts to swap and diagnose with when dealing with one of Yamahas electrical problems.

good luck, your gonna need it.
