Using a car battery to jump start a motorcycle isn't typical or ideal, but it can help get you home or to a mechanic in a pinch.You will risk damaging the battery and/or the bike's electrical system because car batteries have much higher amperage (electrical current strength) than a motorcycle battery.
Check if power is leaving solenoid to starter while cranking. If starter is getting power to it's power terminal but not turning over,see if you can turn engine over by hand. Check sprage clutch assy into engine also. On my bike there is a flat washer spacer that can away into engine if I am not careful,can jam in gearing.
