Hello everyone. I've got a 2004 America and while I was changing oil, I noticed two hoses underneath the bike that attach to the bottom of the airbox. One of these hoses has a small rubber plug in it, the other one is open. The dealer removed all the air restriction/EPA stuff when I bought the bike. Said it would breathe better. Are both of these hoses supposed to be plugged, or just the one, and if they're supposed to be plugged, then what is their purpose?? Thanks in advance.
