I blew out 2 sets of rocker box cover gaskets on my sporty before I figured out I had crankcase pressure issues. One of the rocker box to head gaskets started weeping on the dyno too.

The sporty had a plastic housing. The umbrella valve is inside. It is non serviceable.
i did the Hayden inline breather valve on it and it was a big improvement but still an umbrella valve. But the housing could be modded to make the umbrella close quicker.
Reed valves are better.
