I have noticed that over the last couple days when I initially start my quad its idling low compaired to when I got it. they bumped the idle up once to 1130 and now when its cold its down to 970-1030 and it makes the starts harder. if it was adjusted up to 1100 shouldnt it stay there? when its warm its idling at the 1120-1140 range but when its cold (been sitting for a day or so without being ran) its low and rough starting have to give it some gas even with choke to get it to fire up

 

As you break in your sportsman you may need to adjust the throttle cable a bit. Or may just need a slight choke adjustment.YouTube - ‪Polaris ATV Maintenance & Repair Tips : Polaris ATV Thumb Throttle Maintenance Tips‬‏

 

The carbs idle adjustment screw spring can get weaker over time and the vibration of the motor can make it loose its setting.

 

Most of the time the small wire adjuster cable holder will break and the cable will drop down on the engine where vibration keeps turning the adjuster slightly. Idle will keep changing. If this is what happened,I would order another one(mounts on bottom of carb) or make a stronger tab to hold the adjuster up under the carb. OPT
