    Skat Trak swirl 13/18 impeller for GP12R ?

    Is the Skat Trak swirl 13/18 a good choice for me?

    Gonna be around 140 psi, mildly ported (just removing casting imperfections), 800 grate, Oside Bill recipe carbs with pods.

    I have a brand new concord 13/20 if you need it. It's set back from riva. I bought to run in my gp1300r but realized I need a dynafly

    Is a 13/20 a good pitch for a mildly worked 1200?
