Is anyone else having trouble with the altitude compensating carburetor system (ACCS) on the polaris? I ride in the Sierra Nevada mountains, we park at 8200 ft and ride up to 12000ft. The '99 RMK 700 and '99 RMK 600 all lean out too much and cut out, flip the choke half on and it runs better.....it depends on the jetting, stock jetting is better than a leaned out set up. My '98 RMK 600 runs awesome up there....great from 4000-13000ft, it has no accs! I jetted my brother in laws '99 700 to '98 mains, pilots, and needles (155, 40, and #71), plugged off the accs, vented the carbs into the airbox, and guess what??? It "RIPPS"!!! The accs is now coming off of 3 more sleds. Alot of people in that area are bad-mouthing the Polaris now, they don't know the fix. Has anyone else had any problems?
