    GS1000/1085 head gasket

    So I am going to order a head gasket for the GS1000/1085 . I see the head gasket is the same on for the 850/1000/1100 from Suzuki. So can I use the OEM one or should I use a Wiseco gasket? The Wiseco gasket is a graphite type as is the OEM, I believe?

    Thanks

    I would rather trust my bike to a technician that reads the service manual than some backyardigan that THINKS HE KNOWS how to fix things.

    head gasket

    I use a cometic gasket on my GS1000/1085, it is a fiber type not a multi layer type. No problems at all

        Consensus so far is Cometic

        So another question then, are the rest of the Cometic gaskets of good quality to use everywhere else on the engine? I see many posts to use only OEM gaskets
        In the past I have used aftermarket with no problems.

        Thanks,

          The Wiseco kit also uses the Cometic gasket.
          I ordered a bottom end gasket kit from Cometic. They were of good quality and I would not hesitate to order it again.

            Is the oring required for the cam chain valley when using the Cometic gasket?

              Call cometic, they are really nice people. They will have the 100% correct answer on that. The part number you want is C8030.

                      I contacted Cometic, they said the oring is not required.

                        Glad you got the correct answer. I remembered reading somewhere that they use a viton coating on the edges of their gaskets eliminating the need for o-rings, but I didn't want to tell you that only for you to find out that it wasn't true.
