Ive had my o5 prarie since 2006 it'd never been driven and still has the original tires at 700 hrs , I've re jetted the carburetor and loosened the valves but it still has one problem, when I go for a two or three hour ride and give it a few breaks it will idle really high even if I take the idle screw down dangerously low it still idles high.

 

Hello, when i get on my prarie 360 and put it in high gear it idles very high and i have to rev the engine a few times to get it to go, and once I've rode it for an hour or two it will idle so high that I can coast on flat surface for seven seconds and my gas tank is half empty and it may sputter as if the choke is on.
- I've jetted the carbs
- I put a moose racing belt on
with out racing clutch.

- I ride it for 3 or four hours at a time in the summer and have had the same battery since 2011.
