I have a 99ZX6r that is pretty much street fighter. For some reason in 3rd gear and up it keeps cutting out and runns real choppy. I have herd its from not having the uppers on with the air intake tubes. I have a few friends with ZX's and they all said that theres run the same way with out there uppers on. Now I know there are some of you out there that have street fighter ZX's, what can I do to correct this problem with out putting the uppers back on?
