i ride a 03 gsxr 750. the kit only came with the star. after reading many reviews I was convinced that this would fix all "mis-shifts" (going in neutral between any/all gears) I don't know much about bikes but I was competent enough to install it myself w/ only a few complications. after installion the bike rode fine on the first try but still miss shifts between 4th and 5th gear. my friend said maybe i have a bent shift rod or something but i didn't see anything bent or unusual in there. i would recommend it to a person who doesn't have a 03 gsxr 750. it was at least a good learning experience.
