    Default 2012 RT thermostat

    Thinking my thermostat is gone. The weather is the primary control of the heat guage instead of the engine heat.

    How do I change it?

    Thanks

    If your temperature gauge is reading about 25% when the outside temperature is about 50F and then reads a little over 50% when it is around 80F, you're normal.

    Right. The thermostat is external to the motor. You've got a lot of coolant system plumbing running between the motor and the thermostat for the bypass flow path. On those cool days there's enough ambient cooling that your engine temperature hangs low in the band. Completely normal for the V-Twin. Thermostat failures are extremely rare. Don't worry unless you overheat.
