Turnone air box installation question

I'm half way through fitting the air box and have a small hose which came off the front thottle body but I'm not sure how to route back through the air box or if it's actually needed at all? This is the hose in question:

The pair mod has already been done, can I just blank it on the throttle body if it's from that? Have searched and looked at lots of pics but still not sure.

Anyone know what to do with it?

Thanks man, yeah looks like it goes to the vacuum reservoir under the rh fairing for the intake flapper I think.

Got it all finished off today anyway so just needs a map

One more quick question, do these bikes make a wierd screeching sound with the fast idle on with an open airbox?
Started it up and thought for a second that some debris was in one of the cylinders ? but went away when I pushed the choke back in so relaxed a bit then, still seems strange?
