While test riding a new GS the temperature read out held steady in the 185 range. On my bike from day one is seems the thermostat hunts, just over shoots in both directions and never settles down. The digital read out varies from 180 to 192 and back to about 180 over a 15 second cycle. Does it constantly. (trouble with having too much information probably) How does your read out behave? I'm thinking a simple thermostat change out is in order to settle things down. Thanks.
