aight guys, i need ur help. so many people are sayin so many different things about the 520 conversion kit. first off, is there a difference between a 520 conversion kit and a 520 racing conversion kit? correct me if i'm wrong but is a gsxr 600 03's stock gearing 16-45? so, i was lookin around and i saw an RK conversion kit and it's gearing was 15-45. is that the only thing a 520 conversion kit does to your bike,drop a tooth down 1? should i buy that pre-packaged RK 520 Conversion kit or should i buy the parts separately? :headscrat
