Unknown Hose?

[owlmeat]

So I'm assembling an 1125r that I received in a bunch of totes. Its going together fine, but I have run into a mystery hose. It comes off the right side of the bike, just below and between the throttle bodies. I figured it was a vacuum hose for the clutch, so I didn't give it much consideration when I put the frame on. Well, its not the vacuum assist hose, as that is ran along with the wire harness, on the other side of the bike. Duh. It has marks on the end where a clamp once was.

I've searched the manual, and cant seem to find it. Unfortunately, I cant take a picture of it now that the frame is on, so I've attached a picture from the manual. I THINK that is the correct hose. Anyone have a lead?

I'm 99% sure that is the return hose from the California emissions canister. The reason I know is cause I had a VERY difficult time getting the hose ON to that barb between the throttle bodies when I was installing my Cali Can.
