I'm not sure why you decided to block off the intake and put a piston port cylinder on there. I know this guy who sells the M1 kits, they are expensive but they rip hard. I bought the 19mm rizzato intake off treats and I'm planning on putting a special reed cage on my M1. Its already pretty fast with the 19mm carb, shit intake, stock reeds and a modded bullet pipe. I'll be putting a benessar on there as soon as my taxes come in.
I salute your enginuity and creativeness but these motors are made to work with the morini M1 reed case induction. Blocking it off limits its potential.
