Stock 400ex Carb Jetting

[The Director]

Info Needed: What is the stock jet sizes for the 2001 400EX (pilot, main and needle) what position (i.e. 1, 1 1/2, 2 turns from closed/full-in) does the pilot screw sit in when adjusted to stock setting?

Thanks, TD

Pilot(slow jet) 38
Main 148 (142 for higher elevations)
Needle 3rd groove from the top
Pilot screw 2 1/4 truns out from lightly seated. I thought it was slightly recessed but I just checked mine and it sticks out about 1/8th inch. I'll have to check that later:ermm:
