Air fault for suspension

Anyone have any issues with the back pumping up but when it goes to switch to front throws the engine light and air fault.. it's crazy cold here right now so maybe that has something to do with it.

Which to Buy

Ok... Im going to throw this out there and see what happens! :grin I had an '05 Sportsman 700 Twin (not EFI) recently stolen. I am looking to replace it. I just dont know if I should go with the 570 or spend the extra for the 850? I rode the 570 today, and was impressed, but cant find an 850 locally to ride. I just really use it for hunting, and occasionally towing a small 6 foot trailer load of wood or a log splitter. Im a big guy (300lbs) so I dont want to end up with buyers remorse. Thanks!

450 HO shutting off

I've got a 2016 sportsman 450 HO with 50 miles and 9 hours. It sat for 6 months while i was deployed. But prior to the deployment, last junish. It started running rough, it would shut off while idling and would break up and back fire while accelerating. Additionally. It would get over 20mph. I put fuel stabilizer in it while deployed.

Upon returning, a couple weeks ago. I installed a new fuel pump, injector, plug and battery. I blew out the fuel rail and lines with injector cleaner and compressed air and drained all the old fuel and put new 93 octane in it.

Yesterday, it started and idled fine for 20 minutes so i decided to test ride it. It would only get to 20mph and then bog down or break up.

Today I took the plastics back off as it wouldnt even try to crank. I pulled the brake lever in as usual and nothing. coincidently the brake lights weren't coming on either. So I unplugged the break light switch and jumped the wire and it started. But it back to running for less than a minute and just shutting off. It doesnt idle down or give an indicator that it is going to stall, it just dies.

The map/maf looks clean and dry. I pulled the throttle body off and with the key in the "on" position did a functions check. The only thing I found peculiar was that at wide open throttle the body blade only opens about half way. I took it off and unplugged it. It does move all the way open with my fingers. Has anyone else ever looked inside the throttle body to see how their drive by wire works?

Anyhow, I'm stuck. I feeling like it's an ignition timing thing or anECU, but i dont know.

Thanks for any help.

08′ Sportsman 500 – High Beam Problem

Hey guys and gals,

I have a bit of a problem here (many, I fact if I can be really honest with you lol)...

I was trying to diagnose the problem with the highbeam not working on the 2008 Polaris Sportsman 500 (EFI). The bulb was fine as I tried it in the low beam and it worked fine. So I dug down into the wiring in the pod a bit and I found that the wire has become dry, brittle and has broken. A simple fix would be so just solder or crimp on a connector and seal it up, right?

Well it's broken right before a sealed casing, feels like there are other wires crimped in the shrink wrap.

What are my options? I'd ideally like to modify it so it comes on with the lows but I've never done this and I'm skeptical about royally fudging it up...Attachment 115403
