my daughter was out for a ride on her 350, and it was running fine. she turned it off to take a break. her cousin got on it took off went about 10' and stalled it. after that it won't start. it has spark,fuel,compression but just cranks till the battery dies. it is a very low hour machine. anyone know what might be wrong?

That sounds very similar to what mine did with 8 hours on it. It ran fine for a while (idle seemed a little low). Took a break, went to crank back up and nothing. It had spark, fuel, all that good stuff. It just turned and turned but never cranked. Took it to dealer and the carb had to be adjusted and the idle needed raising. I don't think they set it up right when I bought it. There is an idle adjustment screw on the left side of the engine near the carb. Your manual should tell you which way raises/lowers the idle revs. My friend's YFZ450R wouldn't start and we just messed with the idle tuner a bit. Finally got it right and it ran fine. You should give it a try.
