3/8" (about) hose below air box

OK I read the posts about mystery hoses but got no joy. Here's my issue:

A (approx) 3/8" hose originating from a "T" in the line (approx 1/2") from the "twinkie" to the air box.

Where does it connect (go)?

Small hose off horizontal of tee goes up to front of airbox. Right in front of carb #2. Bigger hose goes up to center rear of airbox. Slides in between carb #1 and #3. Makes an offset to the rear of bike and attaches after threading between the carb bowl vents. Both are vents to atmosphere. Neither is vacuum. Supposedly the one is crankcase venting and the other was for oil return in case any collected in the bottom of the air cleaner. Think that was the little one. It was a dealer add in at first.
