I took the airbox off of my 06 xb9r last night to put new sparkplugs in my bike. I noticed that the upper airbox has the nipple that goes above the rubber snorkel. It also has the inserts to bolt the muffler servo on. I thought that only the 12's were supposed to have the nipple...or was I wrong?

Quote from "The XB Pages":

"9 to 12 Airbox Mod - The early XB9 airbox had a flat top, whilst the XB12 has a vortex in the top to guide air into the throttle body. Replacing the early XB9 inner airbox lid with the one from the 12, has been known to provide performance improvements."

Did you buy your niner new or used? Or maybe this applies to earlier years than an 06?

I bought the bike new. This made me wonder if they started putting these lids on 9's later or if mine just has a 12 lid on it for some reason.
