Question about Polaris ATV
Well there are a couple of things that can cause this to happen. first check your oil and coolent. odd sounding i know but this can cause it. second check and make sure your cluchs are working correctly. next if all that fails then i would check the air intake for blockages and then service the carb.
reply if you need more help :)

I also have Polaris 400-the bogging on hills and under load is most likely a jetting issue. I just rejetted mine to a 167.5 main jet (hex head mikuni) and have taken to the mountains without issue. This is well known problem for this year and model. Bought jet for $4.50 from dealer and about an hour of install time.

IT'S A TWO STROKE. SOUNDS LIKE IT'S JETTED TOO RICH.CHECK THE PLUG. IF IT'S BLACK ,JET DOWN..WHEN YOU CLIMB THE AIR GETS THINNER AND YOU HAVE TOO MUCH GAS.

I have a 2004 Sportsman 400 with same problem. I've completely disassembled and cleaned the carb. Found no problems. Removed and cleaned air filter. New fuel filter. Does anyone know if this model has a fuel pump. This is the only thing I haven't checked. Does anyone know if there is an adjustment screw on the carb I could adjust?
