Im actually in the process of putting a whole 1000 front end on my busa. Ill let you know. I hope it doesnt change it too much. I have a intercooler on my bike and i dont want it to rub any more than it already does.
if your putting a 1k front end on your busa and its rubbing already, its really fixing to start rubbing, it does bring the front wheel back more. are you running a 60 series tire?
