Ok mine comes on 105 degree celcius which is close enough to what the book says. You could have a problem with the thermostat in which case you'll need to test it by boiling it in a beaker of vege oil or similar to see if it completes the circut within the specified temp. range Check you manual or other posts to get the details for this test.

fan kicks on at about 216 (deg F) I think ?

check the fuses, and the fan plugs in at the top of the radiator and should loop around the stiffener at the steering neck...

Well I as said at about 216 to 220...

If it doesnt come on, do this. Lift the tank, under the airbox is the thermostat housing. There should be a plug in the side and the back of it. Unplug the one in the back of it, and jump the two wires, turn the bike on, The fan should turn on. If it doesnt, then you have other problem, if it does turn on then your thermo switch is bad.

<font size="2" face="Verdana, Arial">The charging systems are not THAT strong on the bikes... Also, it takes power to make power... So if you run the fan all the time it take more power to make enough power to run the fan.. This will take power away from the rest of the system and that would make less HP...

This is why you see a lot of drag racers run less lights...
