I just got an 03 CRF/FCR carb, it had the quickshot and an adjustable fuel screw, the main is at 172. Ive been searching the past two days and couldnt find anything helpful...The quad bogs on the quick throttle stab from idle, ive read that the quickshot is supposed to take care of that but mines still doing it. I can make it better by playing with the fuel screw but its still there. Anyone have suggestions on jetting, fuel screw turns, and anything else to help it? Thanks

put a smaller leak jet in there. I dont remember what the stock one is in the crf/fcr but i dropped mine down to a 35 or 42 i think. whatever the smallest one is on magicracing.com. this fixed mine.

#45 leak jet fixes the bog.

As long as the 03 carb is the same as the newer FCRs.
