I posted this in the utv group still no comment...I have an friend that has an 2010 4010 efi mule thats getting fuel in oil...I havent check fuel pressure yet....just wondering if anyone on here in the atv group has had this problem...Thanks in advance:

 

I removed the throttle body today an noticed the flap was opened an lil bit cleaned an going to runs some to see if this fixed problem Ill let yal know how it does

 

I'm not sure how fuel injection works, like if the injector can leak if the fuel can gravity feed to it. That's all I got.

 

Update I cleaned the throttle shaft an this fixed the problem...
