rode my x800 and ran good for about 4 miles, went to park it and it stalled and started smoking and shooting fluid out of the radiator overflow hose, now it won't turn over, did I burn the motor fast or is their something else to check?

I just bought this and was going over it today and noticed that if you rocked the ATV back and forth a little there was some play or movement in the holder unit for the rear wheel shaft, I believe that is what it is called, The wheel shaft holder would move or had play in it where the 2 bolts go through it, Is this normal?

I just bought what a guy told me is a CFMoto CF800 X8 2up, I can't find any information about this model or is he giving me the wrong model, On CFMoto web site they don't list an owners manual which I need and a service manual for a 2102, they start at 2013.
