Gas In oil


I have a 2007 Sportsman 500 efi ho le

There is gas in the oil. smells like gas and is the color of dark Peanut butter.

Any ideas? Hopefully it's not a piston ring problem.

Sounds like you have a bad fuel injector leaking down when you shut your quad off!

Is your oil way over full? Must have an injector sticking, over fueling, how does it run? I would change oil and filter,put some Seafoam in the gas and watch it closely, Seafoam might clean the injector.
