The problem with some of these bikes is that the fan doesnt come on before the light comes on. I had the temp light come on the first time i rode it. Im going to see if the fan comes on when the light comes on. I know a lot of guys down here in florida that have the same problem. Either the sensor is bad or there is a temp senor that is bad. I dont know what is going on. My light came on as soon as I got it home the first day. That is without an hour on it. I call the dealer today where i bought it at and asked them if they have had any problems with other ones, and they said no. I have not rode it hard at all. I have a field that is 300 yards long and that is where i have been riding it at.
