...do you all run with the hump? How much speed do you lose if you put the seat on insead? Do you think the Busa looks better with or with out the hump? I have come to like the seat and grab rail because you can strap things to the seat...why did they make it so you can't store stuff in the hump like you can on the TL...just about 2000 miles and no cut outs yet...when do the usualy start? How do you read the serial number...are the last four digers the ones? My number is much longer but the last five digets are 055xx, so I suspect it is in the affected range as it was made in 4-99 as well...I got MTB in my fuel too...BTW, I got this bike because I liked it as a sport touring bike, not because it was the fastest, so it won't bother me too much if the ZX Whatever is faster or not...I didn't get a ZX 9 cause I didn't like sitten on it, liked the "slower" TL 1000R a lot, so I got one and untill this thing came along was perfectly content. Although there are things about the twin that I liked, I don't think I'll be trading The Hayabusa in on a new one after all...
