Iused to own a 97 f3600 cbr and it was a slow ass turd compared to my 2004 cbr 1000rr, 2001 gsxr 600 track bike, 2007 gsxr 600 fully race prepped track bikes. Even with a sprocket change, that f3 won't keep up with much. I have 15yrs experience riding, and 8yrs track riding/racing. By track, I'm talking about circuit tracks, not 1/4 mile. Anyone can do 130mph in a straight line, try that shit in the twisties and see what happens.
