I think I've done all I can do except , Big bore or turbo. , Brocks exhaust , PC, NOS , Pair-vale removed , Yoshi cams,Short muffler, airshifter, airbox mod, etc etc.. . I guess weight is the next thing. I like the looks of the CYKO wheels ,but 2K for 2lbs of weight difference doesnt seem worth while. ( Not sure about the 2 LB part but I bet I'm close) I have thought about getting another bike this fall but what to get ? GSXR 1000 , New Busa, 08 z-14 , R-1 ?? Or just turbo mine. Not try'in to jack the thread but Less weight or more HP and best bang for the buck is a big deciding point. Does anyone think Rims will get cheaper if the economy gets worse? Would a group buy get them cheaper? I guess buying the rims would lighten the wallet !!
