Think the valve on the rocker cover is an interesting thing, but it wouln't help releave much pressure, it isn't near the size of the breather tube, and if it was open to the outside air,,,woundn't it whistle? Save on having to install a radio in your helmet, no doubt, and I think I have seen this on some engines, but it never could have have much effect of releaving pressure...unless someone wants to point out my miscalcuation...Peace!
