I'd modify the meatbomb atop the bike, spend the money on advanced training, track days, and maybe some one on one tuition with some of the mentors here...
Then I'd do the gearing, put a nice Yoshi on it, then I'd do the ECU upgrade, and then mess with fueling forever, then I'd put Yoshi cam adjusters in, then I'd fuck around some more, then I'd really go to town... Oh, right, then I'd realise that I'd gone to far and start to detune it and wish I hadn't the spent the money, so I could have blown it on a weekend in Vegas that I couldn't tell my wife (if had one) about. 
The gearing is a great idea. And get a suspension set up. Get some nice brake lines, and make sure you have nice pads and you've given the calipers a clean.
It’s diametrically opposed to the sanitised existence of the Lemmings around me in the Dilbert Cartoon hell I live in; it’s life at full volume, perfect colour with high resolution and 10,000 watts of amplification.
