my bikes pretty fast the way it is just piped, filtered, and jetted i dont think the sproket has been done im gona have to count the teeth. i hang with my friends 2 gsxr 600s they are both 2000's andthey arefiltered piped and jetted and one down front 2 up reari am real close when we race. even closer from a roll ive only beat him like twice but i also have abought 50 pounds on him so with a lighter driver would probably be even closer.

 

Sounds about right.A had a 2000 GSXR 600 and that bike really has nothing on my F2 in terms of power, (A little morerace ready for the track inseating position and suspension) but honestly I feel the cbr motor is a better motor. The bigchange is inthe fuel injected bikes. When the 600 bikes went to fuel injection they were able to be moreaggresive with combustion.A 2001 GSXR600 puts down 15 more rwhp then the 2000.With exhaust and a dyno tune the newFI 600s put down around 115rwhp.Plus not to mention there lighter and moreaerodynamic.
