Oh yeah welcome to the board I didn't notice this was your first post. Like blkeh20 suggested there are other ways to improve the performance of your bike than just increasing hp. The best way is to light rotating mass: the wheels, flywheel, clutch are all great choices. You would notice a huge difference in all aspects of the bike's performance(braking, acceleration, and handling) if you get some aftermarket aluminum, mag, or carbon wheel (the latter being the most expensive). There is pretty big difference in flickablity b/w my s4 and m 620 S mainly due to the alu wheels that came stock with the s4 as opposed to the 3 spokes on the 620.

For some extremely interesting reads on enhancing the performance of ducs check out brad black's site at http://www.moto-one.com.au/performance/ It is a great resource with tons of dyno numbers to back up his tinkering. And like the people I talked about in my above post he is also an active member of this site. I'm sure these guys will chime in.
