2014 MXZ800, 5500 miles. Last ride of the season yesterday, I was at speed and slammed on the brakes to see my stopping power on ice - noticed white smoke. Didnít think much of it - drove around and it felt like it was bogging out at the top end, still ripped up to 70. Final run - lots of white smoke, the engine was missing a little and I shut it off. Wouldnít start again, when it did fire - lots of white smoke and nothing from the info cluster. The engine was cooling properly, there is 0 coolant left In the bowl. Sound like a blown head gasket? Havenít had time to mess with it yet. The track is studded, I noticed a couple fins on the radiator bent underneath. Any ideas? Thanks
