Wife has a 2010 300 sportsman. We were out for a trail ride and the quad suddenly quits moving. Still runs won’t move. Pulled the clutch/belt cover and it has about 1/2 quart of oil in it….not water..oil. Removed the primary and secondary clutches and found a seal behind the secondary but it looks good. What am I overlooking ?? This thing has been a money pit since I bought it so I really would like to fix it myself. Thanks for any help in advance.

2001 sportsman 90. I took the carburetor apart yesterday. Cleaned it out completely. I found a few things I had not seen before and man were they dirty. So I put it back together slapped it in and went to adjusting. Now the odd thing is I had the mixture screw all the way in and that’s where it was running the best. Still lacked a little power up hill but ran at least 2 hours never having to push the atv to get it going. First time it has done that. The bad thing is it smokes more than it should and the snappy 2 stroke power isn’t there (yes I know it’s only a 90) so any ideas on what to do? I finally got a repair manual and was looking at the clips on the needle jet could this help?

2011 Sportsman 800……….

Dagone thing keeps wanting to get hung up. The only way I can keep it from sticking is to change the front differential oil once a month. About 3 years ago, I installed the aluminum roller cage but, if I don’t change the oil frequently I end up with a problem.
It suck again yesterday while I was working up a food plot. I drained and replaced the front differential fluid and tried it. Still sticking.

This sucks. Any recommendations????

Anyone else experience this, or happen to have any idea the cause?

2004 700 EFI Sportsman.

Yesterday when riding home, I was going down the road at 50 mph. Then my atv began slowing down. I pressed the throttle and there was no change in engine rpm. I was able to keep it at 30 mph max, but when I pressed the throttle to go faster, there was no change. It almost seems like the atv isn’t realizing I’m pressing the throttle farther.

It starts and runs fine up to 30 mph max. I press the throttle and it accelerates fine but seems to only have 1/2 throttle power. After 1/2 throttle there is no change.

No other issues at all. Is this related to the throttle position sensor not sending the correct information to the engine?

Any suggestions would be appreciated. Thank You.

I have a 2012 polaris sportsman 500 h.o and the display stopped working. The lights still work and the wheeler will run i just have no display. I then realized that the awd is also not working. The battery was junk that was in it so i replaced it. This is where im at and if anyone could help it would be greatly appreciated!

While riding in woods, vines got wrapped around the left front axle and pulled the end of the center shaft off. The clips did not release in the CV joint, and it pulled the end of the shaft off. Broke it at the clip groove just as smooth as if you cut it with a laser. Absolutely no other damage to the shaft, or splines, or CV joints, or anything else that I can tell. Just broke the last 1/4" off the shaft. Strangest thing I have ever seen, and I am a retired mechanical engineer who spent my whole career evaluating shaft and bearing failures.

Now for the question. Is there anywhere that I can purchase the shaft only? Polaris wants to sell me the entire axle assembly with stub shafts, CV joints, boots, etc. at an astronomical price when all I need is the splined center axle shaft.

I can buy aftermarket or used complete assemblies at much better prices than Polaris, but can’t find the shaft only, which should be really cheap compared to the assembly.

Anyone have a used shaft or know where I can buy one?

A friend has a 2013 Sportsman 500 H.O. (camo) with the Engine Braking. They don’t like it. Is there a way to get rid of the Engine Braking? Too grabby going downhill they said.
