My 2013 sportsman 850 xp is dumping fule through the exhaust to the point that I stripped the bike down and drove it untill the fuel smell was strong but there are no leaks. There is only one sensor in the system that I can find under the air intake manifold that must be a throttle position sensor. Could this be faulty and causing the bike to dump fuel? The outlets of my muffler are tan brown, not normal black and my plugs are slightly white (lean) but it’s using way more fule then normal. Took almost 5 gallons to go 54 miles at idleing/hunting speed over the weekend. Any help or knowlage would be appreciated. Thanks.

While using my bike (2013 sportsman 850xp browning edition) last week for hunting I noticed that after idleing around in the warmer weather and once the bike was running warm, fan was kicking in every minute or two, I could smell gas, very strongly. Once I returned home (yesterday) I removed the side panels and fromt clip and rode the bike untill the same conditions were met. Long behold NO fule leak, anywhere. The exhaust however was very very ritch smelling and the plugs are burning a tad white (lean). What would cause my bike to dump extra fuel? Exhaust smells like the choke is on all the time but obviously the bike is EFI. Any one else have this issue or have any knowlage about it? Thanks.

Do dealers sell a service manual for atv’s or do you buy them online, or what?

I have an 04′ with only 60 original hrs on it Ive had a valve lash adjustment done and the only other thing is my carb was rebuilt by a certified KTM mechanic. As for mods the only things Ive done are re-jetted the carb, K&N panel filter in stock air box with lid and 5 Uni vents in the rear of the box, pure polaris/white brothers pipe…………….My ? is it sits more than its used and when I go to start it let it idle for awhile or maybe even ride it a little and when I go to put it away and it sits again for awhile the next time I wanna play with it Im finding lots of oil in my airbox like a quarter of a quart? What is causing this? Any help would be greatly appreiciated

We got out to Busco Beach NC right before/during hurricane matthew and it was an incredible ride! The mud was plentiful and we were the only (crazy) ones in the whole park it seemed like. I whipped up a quick youtube video of our trip, let me know what ya think!

I need a engine, please pm or text me if you have one. 97two.8O4-444three

I broke a front coil spring. I also noticed some play in the bearing and the a-arm bushings so I’m rebuilding the whole side. I’m stuck on separating the a-arm from the strut. It doesn’t seem to want to let go. Is there a trick? I beat on it with a mallet but didn’t want to go with anything heavier since the bolt on the bottom of the strut is actually a ball joint.

It all looks real clean, no rust. I can’t figure out why it won’t come off unless it’s threaded on there or something silly I’m missing…. From what I can see from the diagrams it should slide right off there once the nut and cotter pin are out of the way.

Any advice?

Thanks.
