Was the 07 injected? Sounds to me like a wiring issue. Maybe the power for 07 went through injectors to coils. Just a guess.
it sounds like you need to adjust your idle switch or (knob) located on the clutch side. or you need to adjust your clutch cable, if it gets in a bind it will hold the throttle open on a carbed bike causing it to idle to highI got to start but now the RPM's randomly jump and When you reeve the engine it sticks at whatever RPM and stays there every now it then it will slowly climb down. I think it has something to do with the carb. anyideas?
