How long does it run before stalling? Does it overrev on start up? Things like that, the more specific you are about what its doing the more someone will able to tell you whats wrong.

i learned the hard way to keep an eye out for loose bolts.
expecily on the battery terminals, they have a tendency to vibrate loose and the steering stem bolt i found if you put a little locktight on the threads they stay on a lot longer.

1) check the throttle calibration (need a D&M kit for this).
2) check that fuel is getting to all the relevent places (no cracked fuel lines, the quick releases are flowing ok and their rubber o-rings are in good condition)
3) check the crank sensor position is connected and seated properly.

Good Luck....
