yea it also happened to my best friends 300ex we were changing the jets and he didnt bother to tighten the main jet down all the way and it ran fine for about 30 min then from 1/2 throttle and up it ran like crap, we tore it apart and the main jet had fallen out and was floating around in the float bowl.
