Thank you so much I really appreciate itThey look like the carb vent hoses. The carb vents point straight up out of each carb, you can see them if you remove the gas tank (which is missing a bolt on the front right). The two hoses run to a tee fitting, then a single line from the tee plugs into a round hole in the back of an air filter housing. The vent has to be in dead air or it will cut out when wind hits it. I think they're 5/16" id. but just cut a piece off to match up.
