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.

New to the forum here, hoping someone can help. I have replaced the cdi, coil and sparkplug yet still no spark. The measurements for the igniter and stator are what they are supposed to be, the kill switch is working as it should, the neutral light is working as well. Any ideas where else to look before i start trying to pull it apart for the stator and igniter?

Picked up a barn find that someone had already partially disassembled because the “motor locked up” but they never opened the case. Everything was bagged and labeled, and as I’ve mentioned before- I love a challenge ¯\_(ツ)_/¯
After a couple hours of fun with various pullers and hammers I managed to persuade the magneto/flywheel to come off. Hoo boy what a mess. Then I found an actual rats nest in the clutch cover. ಠ_ಠ
