-Does the fan kick on and off?
-Does the dash light for temp come on?
-What is the scenario when you feel it is running hot....while sitting at a red light in town, while on the highway, etc etc?
- Have you ridden large CC bikes before? Not that I think that is really the issue -- but 1800 CCs of engine will have an overall higher amount of heat coming off the whole system as opposed to a 1300 or 800 etc.
- What do your spark plugs look like? Burning normal or white??
