Just to clarify a few things, I can run on flat ground at ANY speed including 90 mph and no overheating. The second I start pulling a hill, it overheats. The only way I get the temp to rise on flat ground is when doing a hard accel from 0 mph to high freeway speeds, even then it never really overheats, it just starts to rise above normal operating temps because it doesn't take long to reach those speeds @ WOT. Soon as I level off the throttle, so does the running temps. I am sure with more speed I could get it to overheat on flat ground, but I don't need to run any faster than 80 mph anywhere I go.
However, if I even attempt to do any hills with twisties, even going a slow 15-30 mph or 55-70 freeway speeds it will overheat.
It seems to overheat more quickly with more RPM, so even with high load and leaving it in a higher gear and just adding gas to keep speed it will stay cooler vs downshifting and gaining rpm to maintain speed. Did that make any sense?
Lastly, outside (weather) temps don't seem to effect the bikes temps at all. This first started in January of this year. The first time I noticed the high temps I was pulling a 5000 ft mountain range and it was alittle over 40 degrees outside.
Regardless, I'll look into getting the radiator yanked and cleaned and rodded, if not re-cored.
