Check Float Height and reset the airscrew to around 1 -1 1/2 and make sure all jets are clean

My Sportsman runs bad when heated up, but if you add fuel it runs fine again. I had a pick up that had an internal fuel pump like our Sportsman's and it did the exact same thing. It turned out being the fuel pump was worn out due to a plugged fuel filter. Forcing the pump to fail prematurely. I found I had bad fuel in my Sportsman and am going to replace the filter and the fuel pump. I also checked my plugs, MAF sensor, and Air filter, they were fine.

you have down all the electrics ( so have spark at plug ) has to be something with the carby does the spark plug have fuel on it when you remove after trying to start if not fuel problems, does bike have T.P.S (throttle positioning sensor) some on carby, some on thumb throttle etc might be causing problems.

follow ur throttle cable down to cars there should be a plastic screw close to cable to adjust idea but with polaris that screw can be hard to find with all the plasticc they put in way but if u can see carbs easy enough u will see the idle screw
