Dyno output is not everything. It only takes a few easy relatively cheap mods to make the busa very competitive.
For the Gen 2 I suggest to start with:
1) A decent full system exhaust - I used the Akropovic 4-2-1.
2) Install a TRE - I used the GiPro X-TRE.
3) Get a decent sport airfilter - I use a BMC.
4) Get a +2 rear sprocket.
5) Get it dyno tuned with the above setup.
6) Burn the stock rubber, and put road/track tires like the Pilot Power.
7) Attend a track school.
The above should get you around 195 on the dyno. BUT the real difference is on the road - find a twisty road and make that 1000RR sweat to keep up.
