    Dellorto Main Jet Question

    Hello,

    I was just gifted a '99 SR 50 and I am tearing it all down just to go through it all.
    The carb is Dellorto PHBN 12. The main jet has a "14" stamped on it but that can't be correct. Can someone help me ID this main jet so I know what size I'm starting with?


    Scoot is stock for now, I did pull the washer out from the variator. Eventually want to throw a Leo TT exhaust on it so will need to change main jet at that time

    Hahah!! It most certainly does say 74.
    It's a little faint so I mis-read it as 14

    Thanks!

    And I will read through your guide as well, thanks for the link.
