RE: starting problems

bump starts? get yourself a manual and test the voltage regulator/rectifier.

RE: starting problems

how is the voltage on the battery? is it charged at all, or is it low? my guess is still with the reg/rec until you test it.

RE: starting problems

I agree with rrasco, i had the same issue on an older bike.

you need three main ingredients -> air, fuel & spark
one doesn't work without the others
