well i just put a 450r carb on my buddies KFX 400. all stock except a full yosh carbon fiber pipe and the carb. now it is time to jet it. current set up is 50 pilot, 180 MJ, 2 1/2 turns out on the fuel screw. it is lean now for sure, but i want to get it as close as possible the first time around, because this thing is a pain to get on and off.
