Ok here it goes. I got my bike painted alone with engine covers. Now my bike won't start. It will pop start and run great thougt! When I crank it over it slowly cranks for five seconds at most and then nothing. I bought new battery and plugs. It will start with s car battery and the charger hooked up on the charge setting but still rolls over slow. When it. Cranks over it drops to 9 volts but its not the battery. The three batteries I've tried will start my other bi. It's an 04 with 7500 miles. If I hook cables straight to starter it still cranks slow and only s couple seconds. Does anyone have any ideas?!
