My guy that I deal with that sells Sparks, says they reccomend the YZ 450 Dirt bike needle on the middle clip,stock pilot jet, 170 main jet, and fuel screw turned out 2 1/2 turns.

so that would probably be a good place to start. I just got my sparks in, and I'll be dialing in the jetting over the course of the next few weeks. I'll post my end results then.
