so i got a 70cc kit for my moby project, many people seem to have the dellorto 15.15 on it. is this the best for it? others seem to say that a larger carb would be preferred. an intake for the 15 seems really easy to find, but i cant find the larger ones. if i went bigger, where do i get an intake? also, my kit is pretty lame with out a hc head huh?
