Today I took off on a ride without warming up the ST1300 until three bars were showing on the temperature gauge. At the start, outside temps were in the 40's, and only one bar was showing. Later the outside temps rose to the 50's and two bars were showing no matter how fast I went. Is this because I didn't warm up enough at the start, or could it be that my thermostat is failing to close enough to keep three bars showing? Has this happened to anyone else?
