I have a 1985 Kawasaki EN 450 and I rode it around town the other day and when I got home the heat temp gauge was going past half way and I know was getting hotter than it should. Unlike my 07 kawasaki ninja, when I turned off my bike from the long ride the fan does not come on or don't hear it running after I shut off my bike. How can I tell for sure if I take a long trip that the bike is going to cool itself normally and not overheat. It does have coolant and I have burped the radiator due to a previous question.
