Past few days I have noticed my cooling fans coming on when my temp gauge is not even at half. In the past I remember that the gauge would go nearly to the red before the cooling fans came on and the gauge would drop as the fans did their job. I just checked the overflow tank, and it is at the proper level. I ran the bike on the center stand until the fans came on, the reading was less than half level on the gauge, and did not change once the fans came on. I cleaned some of the bugguts off the radiators, but there wasn't that many anyway. Any thoughts on what may be happening here? When the fans came on there was pretty warm air coming from the side vents, so I am surmising the coolant is hot enough to need fans.....I did do a search and found some useful information, especially that the sender on the waterpump is the one that controls the gauge..
