So my setup is pretty basic, i'm running about 800 feet above sea level, and it's been about 25* here. I'm running a uni filter and a motoworks slip on. I'm running a 155 main jet and a 40 pilot jet. It feels really strong in the midrange. The high end might be a touch muddy (least on the warmer days), so i think it's rich, but with the extreme cold coming i plan on leaving it.

However my problem is around the 1/8-1/4 throttle area, if i ride in say second gear with little load it'll kinda buck and stumble a little. When i first jetted it the idle sucked so i turned the A/F screw out 1/3 of a turn and it cleared up. Any idea what i should adjust next?

come on no replies? i know there's gotta be some carb gurus here. I've already searched the carb threads but need a tip.
