I am looking to install a different sprocket set on my FZR600 because I am a poor college student who can't afford a newer bike... I have read up on a few different FZR forums but no one has reviewed the outcome of their sprocket install, which is usually to go from a 530 to a 520 and either up 2 in the rear or just drop 1 in the front. I am looking for more acceleration and don't care too much about dropping my top speed, but would like to not completely molest my gas mileage in the process. I was looking to get a Vortex Racing 520 Front and Rear Sprocket, and to drop 1 in the front and up 2 in the rear.... does this seem too drastic? I only know 2 other people who have changed out their sprockets and the one who got this exact setup was on a 96' Katana and he noted that it was quite a difference with his acceleration, but not enough that the front end was getting light or anything. Any advice prior experience or suggestions that people have would be appreciated.
