vacume lines all over the place

[cboirum]

bought my bike off some kid who didnt know much about it whoever had it before him took all the vacume lines and just left 'em hiding in the frame not connected to anything (3 lines off the tank and one off the airbox) i don't have a manual or anything right yet but does anybody out there know any general info on vac lines for a bike (i'm new to bikes) btw it's a '94 ninja ex250
