Difficult to define. A kind of bogging down but not so much that it stalls. I don't believe it's running on one cylinder momentarily until it reaches higher RPM's. It may be a carb issue. If I have (as disston says) two different Needle Jets than that may be it, because it only occurs at the lower end of throttle. I will order new ones of the same size, plus new Needles. My next move is to adjust the valves.
BTW... Main Jets are 165 - not 160 as they should be.
On a side note. I bought this bike "uncertified" for what I thought was a decent price. Why do previous owners always bugger things up by adding OR subtracting from a perfectly good motorcycle? Today I discovered that I have the wrong center stand installed.
