    copper cylinder base gasket

    What are the thoughts on using a copper cylinder base gasket on a 78 gs 1000? I know we all agree that the OEM are the best as a paper/ fiber type , but I have never heard argument's for or against a copper one. Thoughts from the experienced please ?

      I use copper base gaskets on mine because with the heavy duty studs and 40-50lb torque, the paper ones get squished. Copper base gaskets are also made in several thinknesses from .005 to .020 or so to tune your deck height.
      Copper gaskets need a sealer put on them like gasgscinch or permatex.
      For a stock bike I would use a regular gasket.

        OK question answered.sort of.

        "Copper is for race motors that come apart often. Ray. "

        Is there a reason you wouldn't use one on a street bike? Are they more pron to leaks? or is it just a cost issue?

          They won't stay sealed over time in a street motor that doesn't come apart. Ray.

              I use copper and they do tend to leak a little.
              I'd use OEM on a stock motor.

                Even if Gasgacinch has been used?

                  I actually used gasgacinch and it weeps a little. I am totally happy with them. (copper head and base gaskets)

                    OK thanks!
                    I'm surprised because I was under the impression that they would not leak with Gasgacinch. I must add that I have not used mine yet.
                    Thanks!
