I picked up a new 250x yesterday. The bike would not idle at all started fine but had to give it gas or would just stall. Then as I was riding,it started to bog then just died and will not start and it is a lot harder to kick over now.So what could possibly be wrong with it? I taking back to the dealer on Monday.

Dealer put break-in fuel in it? Did you choke it for too long? Might have fouled the plug.

Hopefully the person at the dealer did not put regular gas in it for break in.

Good point. I'd also like to know what color powerband he selected.

Remember one of my first races in '76. A guy about 15 walks up and asks if I have anything to un-seize his bike.

When i got my YZ250 the idle screw was backed all the way out and pilot screw was all the way in? It wouldn't run barely either. I dont know what to say about the other issue. They also put so much oil in the tank i could hardely see through it. The dealer also could not tell me what it was mixed at either...

Never ever trust the dealer gas. Have you seen most the people working on bikes at dealers?
Not sure I'd let them even check the air in the tires let alone trust they put premix in a 2 stroke.

And that includes those with Oil Injection where you run 40:1 the first tank also.
