I have an 03 RMK 800 159. Seems to me that whenever I come to a stop the RPM's wont drop down to proper idle, I kinda have to burp the throttle a bit for it to drop down. I've cleaned the carbs on it but I'm sure it has to be something to do with them so just wondering what I missed in there that maybe I should double check.
800 Won't Idle Down

Its a little lean at idle. Fatten it up slighty on the idle circuit and it will should cure it.

I agree on the lean condition, try adjusting your fuel screw this will be on the front side of the carb and will be a white plastic knob/screw sticking out. To richen up turn the screw out. I would start buy turning out a 1/4-1/2 turns at a time.
Just FYI
Carburetor tunning
Air screw is located on back side of carb (small screw)
If turned in will richen the mixture this is a Coarse adjustment
Fuel screw is located in front side of carb (white plastic screw)
if turned in will lean the mixture this is a Fine adjustment

To test if its lean, just flip the choke on half way and if the idle comes down right away you found your issue.
In addition to the above suggestions
Check / reset your T.P.S. to 4.0-4.1 volts at W.O.T.
