I own a 2007 Polaris Sportsman EFI X2 model and have for the past months been experiencing loads of issues. Basically the Sportsman will only start if the throttle lever is pushed and will not remain on idle. This situation has persisted for months now and I have replaced the following parts:
Sparking Plug
Fuel Injector
Fuel Pump
Fuel Filter
Fuel Valve
Fuel lines
Power Control Module
The last part replaced was the Power Control Module and the Sportsman was tested and worked fine on a couple of occasions which were days apart so much so that some weeks later I took the Sportsman for an extensive ride and it worked perfectly. This was three weeks ago and today I tried to start the ATV it worked fine a few minutes and decided to switch it off so that I could continue with some prep work. A few minutes later tried to start it up again but noticed that it would only start if the throttle lever was pushed and once I removed my finger from the throttle lever the engine would not stay in idle and would simply shut down. Several attempts were made to start this and also tried to re-adjust the setting by turning the built in wheel like mechanism in the throttle cable but it was to no avail.
The above have been repeating itself on an off basis. Each time a part is replaced the ATV would work and then all of a sudden will not keep its idle. At this stage I cannot think of any other solution other than possibly some sensors which might have an intermitting fault but I cannot really say.
Would greatly appreciate any assistance.
Thanks in advance.

I been working on this thing for like 2 months now and it will not run right, is very smokey, and has a pretty loud tap that i think is in the bottom end. Not sure how much the parts are but i will put the time into it if they are pretty cheap. Im not very experienced but going off how the plug looks and the oil on top of the piston i am getting a whole lot of oil coming in from somewhere, not sure if it can come from the valves or if the rings are just shot, my cheap scope cant really see the walls of the cylinder too well.

Hey guys I have a 99 xpress 300 and I'm having an issue, I rebuilt the engine and it will only start when I put my han over the intake on the car (when I manually choke it), I am not very familiar with plunger chokes.could some one help me understand how this choke is supposed to work and maybe how to ajust it so it works, thanks!
