I've got an aftermarket airbox (Kuryakyn Hypercharger) which I want to get rid of. From all I've read I assumed that the carb must've been re-jetted when the airbox was installed by the PO. However it was recently mentioned to me that because I've still got the stock exhaust that perhaps the bike was not re-jetted. Maybe the airbox was only installed as a cosmetic thing, not for performance. I would really love to lose this thing, but I don't want to turn it into a massive endeavor.
