I started having an issue with my X2 last weekend. I noticed a couple times starting it stumbled a bit while starting, but it ran flawlessly. We rode about a hundred miles Monday, and when we got back to camp, it would crank and not fire unless you gave it some throttle (EFI engine remember) The Air filter is new, the fuel pump sounds good but I had no way to actually check the pressure. Once its running, it runs flawlessly, and there is no noise that it hasn’t had since new, I have a pretty good ear for these things.

Being I have to press the throttle to get it to fire, it makes me think there is an intake valve issue as some have reported in the past (That I have been quick to defend Polaris on lol)

I have 150-200 rpm on the tach while cranking which should be more than enough.

Going to pull the rocker cover this weekend and check lash, any body have any other thoughts?
