i got mine in last march too, i though something was wrong with it from the start because it never came on.
not until i was dooing donuts in a field during the heat of july did it finally come on. and i've only heard it come on a couple of times since. i only ride it hard for short stints though. long rides are usually more casual.
Mine too, never once heard it come on and I even fixed the fan connection problem. Ill get worried when it gets 115 here and Im out riding for 3 hours and I never hear it but for now I think its just a good cool running machine. 8)
