Nick I have noticed it is a lot smoother with a higher rev range, and it does like a dose of throttle, maybe it just doesn't like being in town and running around at 20mph, but then I am not that keen either.
I also notice it wallows a bit on the rear end, Shocks? swing arm? not sure. I have the shocks set on the hard setting, it all feels a little odd. I will get there though.
