Need help asap! Pro issue

[SledderShawn]

I have a 2013 Polaris pro 800 with 300km on it.
I just got back from work been gone for two weeks, when I parked it in my garage it ran perfect. Just started it today and it won't idle right. Idles around 950-1100.
I tried taking it for a hard rip to clean everything out and it revs up to 6000ish and won't go over 20kph. The throttle is wide open too, it feels like it hits a governor

Any lights come on ?
Did you try changing plugs ? just a thought

 

[SledderShawn]

Lights come on. Plugs looks black and very oily

 

[Handlebarsnbullets]

You may have one fouled plug and only running on one side.
I was refering to the lights on the dash. eg. engine light. I should have been a bit clearer on that. my bad.

Was it difficult to start?

Pulling the plugs to check the condition is pretty simple but I would look at the TPS which seems to be a more common and recurring issue with these sleds.

It's running on one cylinder. Swap out the plugs.
