cant you just plug the little tube at the top of the radiator? then you wouldnt need an aver flow tube for the radiator. i was thinkin of plugging mine to make it look a little lighter. then where would the over flow go?... no where there wouldnt bee one. you dont need a breather hose on a radiator right? there supposed to be air tight arnt they?
let me know if im wrong because i dont wanna ruin something. do dirt bikes have ever flow tubes out the radiator? i agree fully, you are not supposed to need this thing. its like a boost bottle, just for looks.
