I have a cylinder head temp. gauge on my 500 and the fan doesn't come on until about 375 degrees,then the fan shuts off around 350 degrees.Normal trail riding,it usually doesn't get hot enough for the fan to run,"putting" around in 1st. or 2nd. gear then it cycles on and off regularily.

I'll put up a picture tomorrow. It was really easy to do. I mounted the gauge in that black plastic piece between the gas cap and the seat.There's a sensor for the gauge that installs like a washer underneath the spark plug.
