What speed are you racing to? Figure that out and gear your bike accordingly for best acceleration while having just enough top end for the race
Since he is against a turbo or nitrous he's goin to have to shell out some coin for motor work. It really all comes down to how much money you are willing to shell out to beat the bus and prove your point what ever it maybe. There are plenty of mods you can purchase and then remove for track days or daily street riding. But we really need to know how the busa is set up. Is that 225rwhp
Stock wheel base or stretched how many inches over?
Stock height? lowered straped
Distance and type of race?
Stock Sprockets front or rear.
The more info you can provide the more informative answers will be. You can always purchase a new chain sprockets swingarm ext full exhaust, front strap kit clutch mod etc and then remove the majority of the items for daily or track riding. Stock vs stock launching a bus or zx14 is a lot easier than any 1000cc supersport. Practice and some mods without knowing the other bikes setup or rider its quite possible to beat him with your stock eng and bolt ons.At the end of the day you have a supersport bike designed for track not a supersport touring bike that is at home on the drag strip. I have a 2007 zx14 and in the straight aways or 1/4 mile stock vs stock I'll beat most literbikes. In the mtns I'm burning brakes scraping pegs trying to keep pace with them and 600s.
