    bolt spacing for GS1100 manifolds?

    I'm making a set of stainless manifolds for a member here and it dawned on me today...after believing I was finished making them...that I made them to match the bolt spacing for the GS750 head. So what I need to know now is if the bolt spacing on the GS750 is the same as the GS1100?

    If not, can anyone measure a GS1100 manifold or head and tell me what the bolt circle is? I need a center to center measurement...

      The 1100 shafty does. What exact bike are you making the boots for? Or manifolds for the boots?

        That is because it is an overbored GS1000 2 valve motor. I believe he is talking about the four valve 1100s and 1150.
