Unhappy Help....backfire and oil loss!

I have a 2007 660 and it runs great but if I stay in the throttle down a long straight away at max speed it starts to backfire from the intake and blows oil out of the intake also. Valve adjustment??????? Totally stock,no mods with 300 hours.

couple things

clean your carb and change the fuel filter

rhino's inherently at long high speed runs will push oil into the breather. you can add a box to help with this.

are sure your not runnign the rev limiter???? it is suppose to "misfire" when you do.
