Went for a ride today for coffee, normal routine of warming until one bar shows up then all is well. After coffee I drive to another town to the Honda dealership where I get a discount on parts, and along the highway not far out of town, I see only 2 bars on the temp gauge. I think about this while riding and go...here is what I have been reading about with the stuck T-stat and poor mileage. So at the dealer I order my other parts, and an expensive t-stat for my girl. After leaving the building, I thought check the antifreeze dummy, So i listen to myself and do not see any in the reservoir, but it is hard to see. I dipped a stick down and none...hmmmm...added a cup of water and now its up to a good level. So on I ride and the gauge is 3 bars steady, in town, slow, faster than posted highway speeds...and all good. I changed oil tonight and checked antifreeze. All good levels and post oil change ride, 3 bars. Question is do you fine folks think this was my warning shot of an impending t-stat issue or just a low coolant deal? OAT was 13-18 degrees C and speeds varied. I do not smell antifreeze from anywhere, no white smoke, runs great and no visible leaks. The bike now has 28300 kilometers on her.
