Ive just finished my engine rebuild and have fired the bike up and everything seems fine however I have a spare hose well I say spare but i think its the tank breather hose however what puzzles me is the hose has three ends like a T shape so can someone confirm for me that one end goes on the tank breather one end goes to ground down next to the side stand and the other is the mysterious hose that goes to nowhere ??? thanks in advance

on the left hand side of the airbox lid is a little doobery for that hose....
