Question about 2003 Yamaha YZF-R6
Hi, Roslyn_carri 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.
8. Coolant too old needs to be replaced.

Check your collant level and if it is full run the bike for 10-15 minutes at idle and see if the fan turnes on. If it does not then either your fan is burned out or you need a temp. control sensor for your fan. To test the fan connect 12 volts DC the the fan plug (check polarity) and it should run and if it does then you need a fan control sensor. If the fan runs as it should, start the process over but with the filler cap off the coolant resivoir. Run the bike again but take a temp reading from the coolant. If it is within manufactures specs, then the thermostat is working. If is is too hot, replace the t-stat.

The dealer or an automotive paint/autobody shop can tell you where the vehicle ID plate. This is different from the VIN plate. Locations differ by make and year. Fastened to a frame member usually.
