    HS50-62023 - Compression question

    Any one know the proper compression reading for a HS50-67023. Just rebuilt one with new rings(measured proper gaps and gaps spaced properly), cyclinder honed, valves lapped, valve guides w/in specs, valve gap w/in spec. Im only getting about 60 psi. Shouldnt it be more than that?

    Hs50 high compression copper head gasket

    Does anyone know the thickness of the old high performance copper head gaskets for Hs40s back in the day? The ones that increased compression. I am looking for something similar for some upcoming hs50(and hs40)builds.

    Powerdyne/Rupp Hybrid?

But I can't find any Powerdynes with that gas tank(looks to be exactly the same as the Rupp Roadster). The swingarm is eerily similar to...
