Another thing to check is that your carb is jetted properly for your climate. If you are running too lean it will also cause over heating trouble. Best way to check it easily is by checking the carbon line on the electrode strap of one your spark plugs after a full throttle run up in a couple gears then key off the motor at full throttle and coast to a stop. Then check the carbon mark. It should Ideally be at the base of the electrode where it starts up from the circle base of the plug. If it's higher you need to go up in jet size until you get it there. Best way to dial in your motor for optimum power and help your motor to run cooler!
