Hey Icehead,
I've had CTS for many years. I've also ridden many different types/styles of bikes. Recently I've owned a R1, a FZ1 and now I'm the proud owner of a Busa. In every instance, I've expereinced my hands going numb. This is a direct result of CTS and not the aggresive sitting position on the bikes. This even happen riding the FZ1, which has a every less-aggresive sitting position then the other bike mentioned.
In effort to lessen the effects of CTS on the Busa, I've installed Heli-bars to raise the handle bars 1 5/8. My hands still eventually go completely numb, not it takes a longer time period for this to happen.
Otherwise, see your local Doctor to address the problem, or as I have do, learn to live with it and RIDE.
As a side note, dump the 750 and get the Busa, you'll never look back.
