2005 trx450r coolant boiling out

A few weeks ago coolant started boiling out of the over flow on my trx and when I was riding hard over fallen trees. Everytime I start it and it gets warm itll keep blowing out coolant. I tested the thermostat and ran the bike without the thermostat. Drained trans and motor oil, didnt find any coolant in either. Fan will turn on before the coolant comes out but the fan definitely doesn't go very fast, not sure if that's normal or not. Radiator isnt full of mud or anything. Blown head gasket? Any help would be great thanks!

Just curious why you started a new thread and why both threads are in the QOTM or Quad Of The Month forum? The Engine forum is where questions pertaining to the engine should be posted.

In your other thread duke416 said it was probably a head gasket, and I agree. You said you were going to check that, did you?
