I am suprised they worked. I went back and looked at the pic again and the throttle cables look a bit tight. Are they? do they bind when turned to lock? I too would have said they won't work since I had to put America cables on my SM to put the America bars on the 4" risers and now with 4 1/2" with 1 1/2" pull back they barely reach.

I learned all I need to know about life by killing smart people and eating their brains.
