Just saw your post, did you get your fuel problem solved? I have a 96 400 Sport (2wd) that had the same thing going on, it ha set for a couple of years, carb cleaned, new needle and seat, new jets, later a new float, same problem. It turned out that the ethanol dissolved the insides of the vinyl fuel lines and it was sending little pieces by the filter into the carb. Replaced lines, problem solved

      I am goin nuts here! I have a 04 400 air cooled 4x4 , I'm a atv,car,truck,mower mechanic for yrs,just sayin. Ok it cranks and kinda fires now and again then after 5 min of cranking and stopping itl start if u touch throttle itl did then u start all over! If u let it warm up sumtimes u can throttle it up other times it just does! Just depends on it? When it stays running it runs awesome,no problems except it just does randomly like u shut key off? Sumtimes itl start right back up others itl do the no start thing! IV put new plug,adjusted valves and hot tanked carb? I'm at a loss here guys! Please any other ideas? I don't think it's anything to do with flywheel? It's not the auto it has a hi low reverse lever on left fender and foot shifter? Help please lol

      Got myself another project. Got it running only to find it has a transmission problem. now I am trying to rebuild it but problem is the bolt that holds on the pull start recoil gear. Any ideas if this is left threaded or right threaded. Left loosy or righty tighty. 
      Thanks.

      Hey, how's it going?
      I'm a new member looking to get some advice before I go to check out a '14 Sportsman 800.  I wanted to get input from you guys that have experience with Polaris machines. I've been riding my whole life, dirt bikes and atvs... Honda, Suzuki, Yamaha, but never Polaris.  I'm looking for advice on what I should be looking for, any common issues, really any general advice.  I couldn't find many reviews of the Sportsman 800 online, so and general reviews on quality/reliability would be great too.
      A little info on the machine. 
      -2014 800 EFI
      -640 miles, 77hrs.
      -Winch
      -Asking price is $5500
      Couple add ons: (nothing major) 
      -Aftermarket wheels with Maxxis tires
      -Front and rear brush bumpers
      -LED lights
      Probably going to see it in the next couple days. I'll make sure to check out all the basics... Fluids, front end, tires, suspension etc.  Plus anything else you guys recommend.
      Thanks for any advice on advance!

      Hey Guys,
      I just bought my first Quad, a 2014 Sportsman 400 HO and want to replace the battery. It's not dead, but the voltage seems low and I'm not sure how old the battery is. What does everybody recommend for a replacement battery? Is there a difference that I should know about? I see Gel batteries, Regular Acid sealed batteries and a lot of different prices. Any help would be appreciated.

      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.
