Nice gain and a good looking mount too. Carb & intake next? When you get to the reeds, see what kind you have and check out my video on You Tube where I explain the different Express reeds and adaptability. There are two different types and one is more favorable than the other.
I think that someone here has been working on a Dello replica kit with rubber manifold that looks pretty good. You want a short and sweet intake tract w/o the "hard" 90* bend that is counterproductive to optimal air flow characteristics.
