slowest busa in the world

[BusaJim]

hey there ,before i write on this post that in no way shape or form ,what i am going to write is meant to upset the old owner ,or persons who worked on this bike.\
oh if i compare my busa and the donor busa,my bike is an animal ,and the donor busa is a slug,

ok everyone knows i bought dj petes bike,
1, bike started fine after fitting a new battery ,
2, bike struggles to reach 80ks in first gear,
3,bike revs fine ,to bloody loud but.
4, air box stripped out ,?????a company spends millions to design the perfect flow ratio and you think pulling it apart makes more power. ???????????
5, muffler gutted??????
6,throttal body's full of greasy dust ,i me lots.
As being a mechanic ,im dumb founded as to why the dual stage air box was gutted because its done nothing for this bike,as i fitted my air box off my busa on it and it rode to 110ks in 1st and flat spotted
7, all the vacuum hoses blanked off.
this bike has 37k on the clock ,the tyre on the rear is shredded,but the motor tells me it would only be pushing about 60 hp its just that much of a slug?

any info much appreciated

oh and saying gutting the air box helps doesnt help me i need real facts cheers

Sounds like the former owner was a tinker I would start with putting everything back to stock at least then you will have a baseline to work from.
