2010 450 exc having problems idling

Hey guys I just bought this bike 2 weeks ago. It was running pretty well for the first 3 hours and then it wouldn't idle and would stall when i would come to a stop with the clutch in. I took it to the dealer where I bought it and they performed the 3 hour service on it and performed carb adjustments etc to get it running well again. I picked it up last night and it was idling fine and I went on a ride today and now it will not idle again.

I've been riding it on some fire roads by my house that go way up into the mountains. On the way up today, the bike was running great. I got near the top and turned back. It's fairly steep so on the way down you are in low gear kinda just droning along. Both times I have ridden this road, I get down and it won't idle. I'll slow to a stop and even with the clutch in it dies.

I'm pretty frustrated because it's a brand new bike so I expect it run well. Do you guys have any idea what the problem is? thanks

I have read on other threads about people putting a JD jetting kit on their bike. Will something like this likely fix the problem?

Proper jetting for your altitude is essential.

Where do you ride sea level or?
