Hello guys; I have a 2006 Road Star 1700 that I put exhaust on and a BAK, Dyna 3000, ported intake, Barons jet kit with 167.5 main jet, a Dyno Jet 37.5 pilot needle, PMS 1 turn, idle at 910, Barons needle on the 4th groove. The bike runs 100% better than before I did all the performance mods, and it is perfect with one hiccup or cough so to speak. When I come to a 90 degree turn (like a city street corner) and make the turn and get back on the gas the bike will cough. Or sometime when I am starting from a dead stop it will cough. This is intermittent doesn't do it every time and usually only after is full y warmed up. There is no popping through the exhaust at all, and other than this the bike is running great. When I blip the throttle it does not cough, and I have looked at the squirt when I blip the throttle and it looks like it is squirting when the throttle blade starts to open, but it is kind of hard to tell when the bike is running, can this be checked when the motor is off? My question is do you think it might the accelerator pump timing and or duration? or maybe the needle needs to be moved up a groove (3rd)? if it's the pump I haven't seen how to adjust the timing screw. I have seen that most people swap the nut on the Duration screw to the bottom side of the bracket and adjust the screw all the way down to get the least amount of duration they can. But I haven't seen anything on the timing screw. Thank you for any advise or input you guys might give.
