i drilled out the plug and backed out the pilot about 1/4 turn. i don't have a ton of miles on her, but after she warms up the throttle response is improved and 55 seems to come up a bit quicker.
the hesitation is gone when the throttle is opened.
the idle seems a little off though. i adjusted the idle screw based on feel, comparing it to the f650 since they are supposed to idle at 1400~1600 rpm. once warm, with the choke out, the bike seems to race a bit. warm up is pretty quick though.
i think 1/4 turn might have been a bit much; i'll play with it and see how 1/8 is.
overall i think it's an improvement. still needs a some fine tuning...
