one way of knowing if its a blown head gasket is to let it run till you think its hot then check the water reserve canister if its bubbling up inside then yeah its a gasket
heres what happend with mine bf750, i took it out in some deep water,, later i knowtised that a week later i was over heating when driving slow but not when i was driving fast, then i came to realise that for some reason my fan was not working, i cheched the braker switch for the fan and it was ok, so i took it to a dealer, and aperently some water got into a electrical conector with 6 wires and messed it up,, now everything is ok, but ur fan seems to work, change coolent and thermalstat.
The six wire thing is a common problem, but an easy fix. If you are going to use it like that I suggest pulling apart every connector you can find and coating the terminals with dielectric grease. I kept the coolant, changed the thermostat for one that fits a 1980's V65 Magna. A test of the t-stat revealed that it was opening at 10% hotter (in Celsuis) than it should. Added a temp gauge, too. Runs at 200 degrees on the hottest days, now. Just right.
I prefer to keep the thermostat in place since I run it in the fall and winter. Warm-up on these carbed Brutes is pretty essential if you want to ride it within a reasonable time after starting it. But yes, removing the 'stat will help in the summer.
i think i was bein perinoid I took it on a 2 day ridin trip and had it loaded up with gear also I was tryin to keep up with all those 2 wheel drive fast quads and had no probs. the fan would kick on and off while ridin I was very inpressed
Make sure there are no air bubbles in it and that the fins are clean enough to see a light through them. Make sure coolant is flowing, too. If not, suspect thermostat or water pump.
No misfire. Runs good actually. It just ran very hot, enough to the point that it was hard to tolerate when you rode it. Fixed it with a new thermostat.
I'm checking to see how hot the ATV would get just idling in the garage. It wasn't a blown head gasket. It was a crap thermostat the was ten celcius too high upon opening.
That stock rad is terrible, go with a triple flow rad its amazing with the new fan

Is there anyone who makes a thermostat that opens at a cooler temp?

It's working fine and flowing like it should. Clean, too. (You really can't shut it off, the thermostat does that).
