You dont want to plug those vent lines before you play in water but you do need to extend them to a higher spot.....If you plug them the bike isnt going to run right the only one that you should plug is your drain on the bottom of the carb.........just get yourself alittle three way splitter and turn both of those vent lines into one then run it up into the 3rd light houseing and youll be fine as long as that doesnt go under water never thought about putting them to the air box
