i think the adjustment for the bowden cable is where it is attached to the linkage as shown in the pic. i am still not sure which direction to turn although loosening it was definitely not the way to go for me as it stopped downshifting altogether and the shift points went lower. i have tightened it 1.5 turn (9 flats) and it is back to where it was before with no real improvement. maybe there was too much slack to start with. i'm giving it another half turn tomorrow morning.
george just said that he adjusted the knurled knob to get rid of the slack in the throttle linkage but i'm pretty sure that wasn't part of what steve said in the original thread.
