    Barnett Clutch extra steel plate?

    Just picked up a barnett clutch kit for my GS750. Building an ahrma superbike for racing. The barnett kit has 8 fiber plates and 8 steel plates. The stock set up I pulled had 8 friction and 7 steel plates. I have heard of guys running an extra plate but would like some advice on this. Do you guys recommend using the extra steel plate since I am running the heavier barnett springs in it?

    The perplexing thing is that service manual for this '77 gs750 shows 7 fiber plates and 6 steel plates. Hummm.

    The extra plate runs ten and ten.
    There is a steel wired in your clutch basket. Have a look. That makes eight and eight.

      Thanks

      Thanks, I buttoned her up a while back. Tearing another one down now so I'll take another look at the stock one.

      That 1100 of yours seems impressive and expensive..!

        I've been messing with it for years. Blew up a few and finally have a runner.
        Yes it costs a lot but it's my hobby

          Fear not.

          They only get expensive if the wife finds out.

              take the wired in steel plate off of the inner hub and machine the surface smooth so your stack starts with a fiber and ends with a fiber.

              a little measuring / clearancing is required but the end product is nice.
