Check all the grounds first, especially the one bottom rear of the motor. If all are good try shorting across the 2 main solenoid terminals with an old screwdriver or similar, need to do this swiftly and firmly to avoid excessive arcing. If starter turns ok then, solenoid is suspect.Opinions, was riding this weekend, stopped for gas went to start and got just clicking noise. Turned off and back on started fine.
Made two more stops and bike started fine. After the next stop nothing but rapid clicking sounds. Had to bump start to get home, since it's been home nothing but the rapid clicking sounds when starter is activated.
I initially thought battery and bought one yesterday but haven't installed yet. But put bike on tender after returning home and after a full day still only clicking sounds. Now thinking possibly solenoid or starter.
