    kerker exhaust

    i have a 78 gs750 bone stock. im buying a kerker 4-into-1. im wondering what size jets should i move up to. can i just replace the jets or do i have to buy a kit

    this is quoted from DynoJet or Vance and Hines, from a document i recieved from another GS'er:

    GS750 2Valve - Increase the main jet to a 115. Pilot jet should be increased to a 17.5. The needle main need to be raised a notch (lower clip).

    //

    i suggest raising the needle, and taking the top of your filter air box off.

      buy your jets online. bikebandit has a good selection, but their shipping is rather slow.
