    Need help on GS750 performance mods

    Hi:

    I have a 1978 GS750E with Jardine 4 to 1 header, air pods on the carbs, and a Dyna S ignition. I am trying to set the bike up after years of storage.

    I could use some help on the following:

    What size jets should I use in the carbs, I bought a rejetting kit with four different sizes.

    What should the plugs be gapped at?

    Carbs have been cleaned and bench synced but when I use a Motion Pro synchronizer, the number 3 carb is showing 6 levels below the other three which seems to level out. Adjusting the air screw does not have any effect.

    Lastly, can anyone recommend an aftermarket ignition coil to go with this setup?

    Thanks,

    Pete
