    K & L Valve Shim

    Wadelundeen in IN

    Nice shims

    I order 12 shims all of them are the right sizes I ordered. Each shim has a easy to read engraving of the size.

  • Cylinder Works Big Bore Replacement Top End Gasket Kit

    Cylinder Works Big Bore Replacement Top End Gasket Kit

    Garrett in PA

    These gaskets are solid.

    The metal gaskets that cylinder works provide with the big bore kit are very good quality. I had to replace my head gasket due to overheating and blowing it, but with as hot as my bike was running, I'm glad the gasket blew before anything else did!!
