There is a hose that runs from the middle of the back of the air box down to what looks like a pump. I believe the repair manual calls it a PCV hose. This hose is about 10 inches long. Does anyone know what this hose connects the airbox to. I recently disconnected the hose to remove the airbox and I forgot to reattach it (like a moron). I ran the bike for about 10-15 miles before I realized. What type of damage may I have caused? I know this is very vague and if anyone can help me I would be both grateful and impressed.
