Engine runs rough
I recently purchased a 2011 800 Pro 163" with 620 miles on it. I use non-eth fuel and between 5100-5800 rpm it is not smooth, it has kind of a stammering/growling sound..give it a little more throttle and it clears out and takes off like a rocket. It makes it hard to ride in the trees at a lower RPM. Anyone else have/had this issue?
