Good review Steve.
Only thing I would say is that with a new ECU, Throttle Position Sensor and richer fuelling my bike runs very smoothly. It was a pig at low speeds before as it was part of the 2005 production which stalled at low revs. The new ECU fitted under warranty fixed that problem. It's smoother now than any other short stroke big single I have ridden.
I agree with you about the fork dive and will be fitting a Kev spacer mod when they next become available.
Final point: why did Yamaha fit an 'off-road' seat with seams on the ridges? Style over function? Mine will be re-covered with some BMW 'coarse' fabric to make the ride more comfortable - �50 by Tony Devlin in Huddersfield.
