Under normal riding conditions your fan shouldnt come on. If your running high rpms and not moving fast like sitting and cranking donuts with moving enough air through the radiatior then it will come on. I dont know the exact temp the fan comes on. When you turn it off when its hot with the kill switch the fan will stay on. If you turn the key off it turns off.
