What is next;
    Repaint engine, should have used Dupli-Color engine enamel instead of the High Heat Ceramic
    Like to have the crank lightened and balanced.
    Degree the cam for some more horsepower.
    Could go to 750 jugs but that one is up in the air.
    If I can reach 65hp with this configuration I would be happy.
    Dyno testing for max hp and finer carb tuning.
    Fix center stand so it gets hidden behind the pipes.
    Replace dirt track tires with some gooey road tires.
