That is if the problem is actually a fuel starving issue and not something hing else.
that mayb be true but from what i noticed is that these fuel lines need to have some length so the fuel sits in the tube longer. on my buddies stock motor the fuel would either be 3inches from the carb or after a day of riding filled all the way to the top. if it were completely free flowing then id assume that the whole fuel line would always be filled with fuel. maybe its a tune problem? im waiting on the expansion chamber to actually tune it properly, but if i have to, i can either buy a rear rack gas tank or the gas barrel that sits behind the seat lol worse case scenerio of course, jus to lengthen the fuel line. Oh and also when i ran my other bike which had a reg gas tank i never ran out of gas because the length of the line
