Zip Ty Question

I just installed my zip ty. I had trouble at first noticing a difference in throttle response. I have it turned out 2.5 turns now, definte improvement on initial throttle response, but there is still a slight hesitation and bog. I havent done the BK mod yet, because I looked at the black cam adjustment when twisting the throttle and it doesnt appear to move much at all. I have a 2001 wr 426, yz timing, stock exhaust, uncorked, zip ty, throttle stop out, air cleaner unrestricted.

any thoughts?

fuel mixture screw won't fix bog. Try different leak air jet.
