bryan, could I ask what your jetting is on your 24mm Mikuni? I had mine running perfectly with no bog off the bottom when I crack the throttle open but since it warmed up and I changed my Pushrods (shorter) I got the bog back again. Mind that the temp difference was about 18 degrees hotter when the bog came back. Right now I have the jetting as 20 pilot (2 turns out) 140 main and stock needle at middle clip setting.
