Problem is high idle...4100-4200!! Idle screw backed completely off & screws @ 1 1/2 turns out. Tried at 1/2, 1 & finally 1 1/2. Can flip choke & bring idle down but goes back up right away. Scared I'm on the edge of tooo lean!! Checked plugs at WOT & they looked ok, maybe a little on the lean side but more golden than white but not sure how to fix pilot circuit. Sled VERY strong throuout powerband, and EXCELLENT throttle response but high idle has me nervous...My CR 250 would do this if you tried to turn idle knob/enricher enuf to maintain an idle. It would "hang" when you let off gas, doing that (this should be good) ding-da ding-da ding-ding-ding sound that goes along with an over-lean circuit. Sled does this too, though not as bad. What do I need to do?? Would loosening cables @ top of carbs help (but the slides appear to be completely closed already)? If I jump up a size on my pilot won't my off-idle power suffer. When I turned screws in to 1/2 or 1 turn there was basically no change in idle speed, but my response suffered so that's why I'm back to 1 1/2 turns out. I'm lost!!
This sled has the rack style carbs right,if it does the little thumbe screws on tha sides of the carbs are fuel screws and the more you turn them out the richer it gets (oposite of kiehns or round slid michs) the idle adjust screw is on the top next to the cable . does this help?
yeah that helps...plus makes me feel somewhat stupid. I had no idea this was the case...several people I had talked to said in was richer, out was leaner. You sure about this??
I am looking at what I think is a 1987 Polaris Indy Trail, could someone please help me verify what sled this is.

I would like to know what engine this has as well. It is 2 cylinder
Hello All,
I have a 2004 Polaris Frontier touring 4 stroke liquid cooled sled with the 136" x 15" x 1" track with the 2.52 pitch track that I use purely for ice fishing. Can I stud this track without damaging the tunnel or rear heat exchanger? I purchased 108 Fast Trac 1.175" triple X series...
While doing Polaris oil change there was a burning smell during the key cycling stage. After oil change there is still smoke under the hood coming up during idle.
95 polaris 500 efi - bogs down after warm up. I see others with similar problem. Machine runs fine for 20 min. Then it begins to bog down. Shut it off for 10 sec, something in ECU resets and it runs fine for 10 min, then begins bogging down again. Shut it off for 10 sec, runs fine for 10 min ...
