I have a 2013 Sportsman 850xp HO Limited that is giving me fits. It runs well when it’s in gear, but it idles very high (and rough) which doesn’t allow me to shift it into gear without shutting it off. Generally it’s idling around 1600 to 1900 RPM. Sometimes it idles very rough and even occasionally stalls.

My local Polaris shop is swamped with work, so my friend who is a mechanic is going to look at it. He does ATV and motorcycle repairs as well, so he’s familiar with the machines. That said, but are there any common issues with late-model 850xp machines that could cause these problems?

I did some searching around and found issues with older and/or non EFI models, but I didn’t notice anything about this machine in particular.

Many thanks in advance.
