[QUOTE="supertankerm60a3, post: 1039305, member: 20650"] It seems to me that if you put together enough data points, you would have a smooth wave form fluctuating regularly by 40 degrees. Co-incidentally, where we expect the thermostat to open and close. I would guess that at speed, in relatively cool ambient temperatures, the thermostat closes, the coolant trapped in the radiator cools to near ambient, the engine heats back up, the thermostat opens, allowing alot of very cool coolant to flow into then engine until the thermostat closes and the cycle repeats. I think it shows that Yamaha over built the radiator. That is a good thing. I would expect these "fluctuations" will disappear when the ambient temperature gets hotter. [/QUOTE]
