Im been having a bogging problem from when i purchased this bike new, when i open the throttle about 1/2 way+ from idle it wants to die. I keep hearing about the AP mod but im wonder in it might be too much fuel. It sounds like it should fix my problem but i would rather not grind my diaphram just too see it not work. my fuel screw does nothing for the problem.

my current settings are 168 main, 3rd clip position, quickshot and everythingelse stock.

Any input would be great. Thanks

sounds like it still may be lean on the bottom.since you already have the quickshot i wouldnt put the 55 leak jet in it and maybe just put the needle at the 4th pos.mine runs great with the 55 lj,42 pilot and needle in the 4th pos.
