Ok i have a 2007 sportsman 800 efi x2 model it ran greta for a long time then one back fired and never started sense i am a car guy dont know much about wheelers so i took it to the dealer where i bought it they fixed a bunch of stuff then i went and got it. Started it up and it ideled fine so i went to hi the trailes a little soon as it warmed up about 10 minutes into rin it lost all power and ran like crap al most like it was getting to much gas well it is at another dealer yet again and they cant find the issue. They thought at first it might be the push rods (Polaris said it might be them) so they replaced them but with no succes still did the same thing so yet again it sits there with peeps trying to figure it out its been there almost a year so please any info anyone may have would be great to what maybe cuasing this.

Ok had to register under new name wouldnt let me respond under the guest account so anyways the dealership said they replaced that wire harness and its not kickin anycodes that i know of ill call them and find out. The kicker is it went in just becuase it wouldnt start and it came home running like this ill get some more info for ya it will get posted tommorow
