I just bought an '02 300EX and it has a 125Main jet in it, not sure on the pilot. It has a White Brothers slip on and a K&N with an outerwear also. The problem is it cuts out when you rev it up from an idle, but when i pull the choke up about a 1/4 of the way it revs fine and doesnt cut out. I'm wondering if the air/fuel screw may be out of adjustment....any help is appreciated.

yes on bottom right above the starter might be hard to get to not much room.
