I have a 2000 Polaris Sportsman 500. A year or so ago we got it running after replacing the kill switch. It ran great but after some use for a couple months it got a flat tire and for some reason we just forgot about it and it sat for some time. Before it sat i replaced the gas cap, fuel filter, fuel pump, petcock, battery, starter relay, oil and oil filter. I recently went to start it and it started so quickly and without choke or throttle but the ATV wouldn't move till about 1/4 throttle and it wasn't really a smooth ride until 1/2 throttle. it also would bog out randomly after you came to a stop and sounded like it was getting too much fuel. I cleaned the carb and adjusted the air/fuel screw to 1 3/4 turns out. I also messed with the idle and the throttle cable adjuster up on the handlebars. It's safe to say it now runs worse than when i started working on it 2 days ago. It takes more effort to get started and bogs out idling after about 30 seconds. I tried adjusting the idle but every time i do it'll get to a sweet spot but after driving it down the driveway and back the idle will go up and down to the point where i can't put it in gear because the gears will grind. Any thoughts or ideas would be greatly appreciated. Thanks

All I have been through everything. Bought brand new. Throttle safety switch Cam and rockers ECM Carborator Stator Fuel safety switch Battery Everything every forum has spoken of I've bought sealed airbox completely tight unplugged black wire on trans. I have literally done everything in the book.Checked oil today full of gas anyone no anything what might b wrong. Next I'm taking head off and making sure valves seat any ideas.

Just bought this ATV. Wondering if my gauge from a 2003 will plug in and work. I know mine does not have a fuel gauge, but if the rest works, I am in.

Problem: The ATV starts and runs at idle perfectly. But as soon as I open the throttle, the engine starts to slow down until it stops. On the attached video you can hear the sound of how it works: see video below Prehistory: there is a Polaris Sportsman 500 1998, which for about 1.5 years stood in repair, including also replacing CDI with one taken from the same ATV. Finally, the vehicles were on wheels, traveled several kilometers and overheated - forgot to fill the antifreeze Came back home in small moves. The next trip started well, but after 10 km there was a feeling of a small drop in power (even as the vehicle got warm completely) but still drives. Next trip - the situation is repeated. The next test of ATV through time and a huge loss of power from the very beginning. The engine sneezes, does not want to go more than 5 mph. What has been done: the carburetor has been replaced with a new one (inexpensive, $ 40), a new spark plug, a new ignition coil, the engine head has been removed, the piston is in good condition, valves were corrected - but the problem was definitely not in them. Ignition control unit is suspected. Who faced similar? Please help in solving the problem. Thanks in advance.

Looking at a 2004 Polaris Sportsman 600, with new winch, new 48” plow, 2200 miles and clean. Serviced 200 miles ago, new battery. Selling for $3100....yay or nay. Color is yellow

Has anyone had any luck putting a different gauge on this machine. Would you happen to have the wiring diagram?

So yesterday I picked up a 07 polaris sportsman 800efi stealth edition for 3k. Will lead a pic ltr. In good shape. Here's what's wrong with it: The rpm needle doesn't work just like my other sportsman... not too worried ab that. The motor doesn't sound like it's running quite right and doesn't feel like it has much more power than my 500. I'm thinking it needs a tune up and some fresh oil.. but also it feels like it's running rich. It's a little buggy when you goose the throttle and sometimes farts when you let off (like I little backfire out the exhuast). I'm gonna check timing and valave clearence on the motor first but thinking of putting a tuner on it? Anybody got a suggestion? Mainly looking for more power.

I found a black rubber hose hanging down from the front of my Sportsman 850. I'm trying to see if it's the diff vent hose, or something else and if it's something else, what it's supposed to attach to...

I have a 2017 Sportsman 570 SP with a power steering issue. Dealer tells me my machine is one that is not covered by recall and offers no help other than bring it in they will look at it. Any ideas?

Does anybody know how to determine which of the 2 key blanks fits my ATV. I have called several dealers, and Polaris and nobody seems to know which key fits which ATV. I thought with the ViN number they could look it up, but apparently not. I hate to spend the money at Polaris for a key blank and then pay a locksmith to cut it, but the locksmiths around me don't have the Polaris keys in stock. I find them on Amazon and places, but I can't tell which key blank is right for my ATV. Any help would be appreciated.

Charging issue? I have a 2017 Polaris Sportsman 570 EFI. Yesterday, I start the machine and it says low power (10.6-10.8). This machine is on its second battery. This is a new AGM battery with 50cca more than stock. Should I look at the regulator or stator? Thanks!!!
