2015 Mule.....same problem with not running right, bogging down, misfiring .....on mine, there are two fuel filters, one under seat, one closer to engine......that was the issue......dealer changed both, back in business.....................
I’ve ordered some stainless pipe and a stainless silencer. It will be a while (probably 6 weeks) before I can get it all installed, but I’ll post the parts and results then.
