I have a 2000 Polaris 600 XCSP and have recently noticed an idle issue. After riding for a while and come to a stop and idle, the idle remains at 3000-3500. If I put the choke on half choke it will drop it down to the specified 1400 rpm. It will sometimes climb back up to about 2000, sometimes stays at 1400. I've heard that in the September SnowTech magazine, has a red Firecat on the cover discusses this issue. Does anybody have an idea or the magazine to give me some help. Thanks
