Cam timing or a malfunctioning decomp mechanism is the first place I'd look. One tooth advanced will render the AD system functionally inoperative, and the bike will run like a WR.

That happened to my 03 as well, couldn't decomp it for the first couple times I tried starting it, but it then "fixed itself" (I assume it got lubed better or broke in or something) and it worked fine after the first couple times I used it. Ride it a couple times and then see if that helps. Also, if you just apply hard, constant pressure (not jerking it) when it gets TDC, it will eventually move past it...

I rode with a guy before that never used his decomp release on his 01 YZ250F! THat had to suck until we showed him how to do it right!

If you can't kickstart a bike, is it really a good idea to drag it behind a truck?
