Need help,over heats at low speeds

[leepster01]

I have a model 5892, 95 sportster with a single engine. At low speeds, the over heart buzzers goes off, I have replaced the sensor. If I start driving some the buzzer goes off. Also noticed no water coming out of there back at idle.

Your cooling system is plugged up. Not much to help with. Start pulling hoses, and look for the blockage.

If you ride in sandy water... the cylinders can be filled with sand too. So... you may want to remove the head to inspect things.
