So i bought this dirtbike a few months ago. The first thing I did was change the oil, flush radiator, etc. The oil looked good when i drained it but went ahead and replace it anyways. So Ive put about 5-6 hours on the bike with no mechanical problems at all. I went to change the oil again last night and it was a little milky looking. Kind of concerned and dont know what to do. I am not losing coolant other than if I fill it to the top and run the bike it drops down about a half inch and then stays at that level consistently. I did get stuck bad in the mud a month ago and had to lay my bike over pull, lay it over pull, and eventually had to be towed out. Im not sure why I would have water in my oil if Im not losing coolant. Should I be concerned or not? What should I look for? Any help would be much appreciated.
