I just bought a 93 Interstate with about 37K miles. The temperature gauge never goes up more than 1/4 of the scale while I am riding. I am wondering if maybe the thermostat is stuck in the open position. The gauge does start to ease slightly higher when I sit an idle for a while, but as soon as I take off the needle goes back down to 1/4 up from cold. Should I be worried about this? I am going to check the gas mileage to see if it is low. I am wondering whether the engine is ever getting up to the best operating temperature. Anyone have any suggestions. Thanks.
