i have not been able to find a solution to my problem anywhere i need help. i bought the bike knowing it had no spark. i changed the coil for one i had that i knew was good. nothing. i checked the stator for continuity across all 3 wires they all showed continuity. checked the wire to the coil no voltage. the wires to the headlight showed 6.7 volts. is my primary coil bad? could cleaning the flywheel fix it? haven't found anyone local with the right puller. any ideas? thanks.
