    Finally got around to the carbs.

    I'm pretty sure I read somewhere that the haynes manual
    messes up on one of the jets or something but I did my little diagram based on
    that since it would be easier to locate what it is right in front of me...
    Also I kept them on the rack still, and i'll be doing the mixture screws tomorrow.
    a PO removed the caps so i'll be able to get at them!

    Main air jet:205 on all 4
    pilot air jet: 50 on all 4
    air compressor jets: 36 on all 4
    main jet: 112 on all 4
    pilot jet: 43 on all 4

    by the manual it says for the UK model it's 112 main and 43 pilot
    and all others to be 110 and 40 so i'm guessing one of the PO's f***ed up
    or this is a UK bike lol.

    The needle seat which seems to have that little filter screen on it were missing
    on all 4.

    What do you guys think about the jet sizes and missing screens?

    forget about the screens, use a in-line filter

    My 82 650 Seca is Canadian as well and seems to use parts from UK and USA bikes, so you have to kinda follow both. Not sure what your model is

    I've noticed that! Is there some way we can know what's stock for our Canadian bikes?
