I haven't ridden my ZX in close to a year... 50mm going on a street engine, and the Corsa engine is getting further mods to the engine case.
I'm hoping the Corsa engine will break 90 MPH, and the 50mm will street at 70... 2t's are too much fun to sit around un-riden.
Adding that Malossi spring will change where the pulleys ride up hill so it will help. A lot!
I'll see what I have left over after these builds, and maybe I can get together a "care package" for you.
I really think my goal is to build all the bits into two great engines, and sell the entire package. All the extra stuff, I can get rid of separately.
I'm thinking I have pipes, carbs, rollers, manifolds, cylinders, too much sh** to list here.
We'll see in a couple weeks when I get my parts...
