The ECU has probably been flashed and he’s probably running some aftermarket Cams the bolt was probably loose. How’s the valve shims they should be fine . The only way to tell if the ECU‘s been flashed is to literally looked at it on the computer even then I’m not even sure if you can pretty sure you’d be able to if you hook it up to the computer to look at the Maps values.
@@haya262000 I love the Hayabusa. I’ve got a 2003 GSXR 1000. I’ve been working on got the manual for it , fast bike not as fast as the busa thought . The older 2003 back are a lot easier to work on they don’t have all the technology, sensors for everything they are nightmares . lol for me anyways, I prefer to control the bike not a computer
I have a 2002 Hayabusa. The first generation Hayabusas' are the fastest. That explains why your 03 is so fast. My ECU was flashed so it will definitely outrun time lol.
@truckdriver_8469 thanks. My other 2003 is in stock form and the first time I took out this copper 2003 I was shocked at the acceleration. It definitely surprised me.

@rezkidgamingyt4725 thanks. I was thinking the same thing about the cams. I am going to pull the cam cover to verify.

@rezkidgamingyt4725 I had a few 01 - 02 gsxr 1000's. These are my favorite. I turbo charged them back in the day. It brings a hole new meaning to fun

@@haya262000 Any first generation Hayabusa from 99-07 is extreme horsepower. They are very powerful street bikes.
