I hate CVTs. No real control over the ATV.

I would suspect the oil seal behind the H20 pump as well. Could be head gasket too though. I'm not sure if there is pressurized oil behind the H2O pump or not but I do know that there is oil pressure though the head gasket and if it ever got too hot it could damage the head gasket and the oil would leak into the coolant system. Some coolant would leak into the oil after shutdown and would collect at the top of the engine. Pull the rocker box cover and see if there's chocolatey goo in there. If there is you've got a faulty head gasket.
