Try disconnecting the battery while the vehicle is running. if it shuts off it is the alternator, if not then it is something else.

2003 r1 over heating


Hi, Smokedatkill and the usual suspects are:
1. Low coolant level.
2. Restricted radiator air flow.
3. Faulty thermostat.
4. Coolant pump or fans inoperative.
5. Vent hose crimped.
6. Air in the coolant and needs bleeding.
7. Engine idling too long or bike moving too slow.
