I have a 2011 850 touring and when you leave off the throttle and the rpms drop back it goes down past the idle setting and hunts for a couple of seconds and then smooths out.
Plenty of power.
Just changed plugs and tried to DeCarbon the silencer.

Anyone have any ideas to try?

Throttle body or sensor dirty or an air leak somewhere would be my first guess.

My 850 hunts at idle until warmed up. I would be interested if you find a solution.

Possibly air filter as well. There is the oil in the air box issue on them and maybe you got some oil in the filter causing a restriction at idle.
