Just wondering what the running temp of the motor and the coolant would be when you are running a 13:1 or greater piston on a 450 during mx race conditions, Also what the temp is for a stock 450 motor during mx race conditions, thanks.

Well its not what your looking for but I have a 12.5:1 piston with a 480 big bore and my bike runs about 175. I have the ESR temp gage on my bike and I do not ride mx at all but have pushed the bike pretty hard in the dunes and drag racing.
