So I pulled the carbs off the '99 (California bike), and comparing them to the set of '08's I picked up from Pinwall I see that the air hoses...I think??... shown in the little inset of the carb parts diagram page are pluged off on the '08's. So I suspect the line goes to the smog valve mounted to the lower frame of the '99. Question??? What would happen if I left the line disconnected from the carbs, and just pluged the end. The lines connect to only 2 of the carbs. #2 and #3, and the bibs look like they come out of the bowls. Are they maybe vapor recovery lines, or?? Would this also disable the smog system?? I'm in the dark... Need some advice here....
