What is the best 1/4 mile time a stock Hayabusa can do

[m8ee]

10.2 not lowered with stock everything if you weigh 100 kg.
You should just be able to get a 9 if it is low and dyno'd.

You do have to go to 4th on stock gearing, I tried this last
weekend a few times and it always hit the rev limiter if you
try to keep it pinned in 3rd.

I try to change at about 9600 rpm, don't back the throttle
off, keep it at the stop and just give the clutch a tiny little
feather touch.

Practice lots....... Then do it some more....... GOOD LUCK!
