OPT, I've been intending to investigate this on the right side of the Carb. on a 2001 Sportsman 500 HO. My manual doesn't show it exactly as it is. The manual I have is actually for a '99-'00 500 not an '01 HO. It is a cable like piece. I tried to attach pictures of it but not sure they went through.
Thanks!

 

High dollar idle adjuster.. Clip on the carb has broken that holds it up in place.Common thing to happen on these. Item #53. 2001 Polaris SPORTSMAN 500 HO (A01CH50AA) Carburetor A01ch50eb | Cycle Parts Warehouse You might want to get it off the exhaust.. Either get the clip or secure it up somewhere. Not a bad idea on lubing this cable as they had a habit of corroding and not being able to turn.

 

OK. The clip is still there. I had it out to show what I was talking about. Thanks! I knew you'd know, have a good one.
