Welcome to the forums. Did you check your oil? It sounds like you may have gotten water in your oil.
It would probably be milky if it had water in it, but I think I would change the oil anyway, just to be safe. If the 4-wheeler was turned up sideways enough, it will get some oil in the cylinder, but it should burn out after a while.Yes,
There is no milky substance at all in oil. I was always told that if its not milky, there is no water in it. Is that always the case?
