Bought the Bunn Breather, with a little bit of modifying, oil dump issue solved. Had to put on a larger diameter hose for the outlet, and stuff it full of aluminum window screen mesh to prevent oil from exiting the bike, used clear hose  to verify that it's working.  It would work fine  before the oil heats up, then the thinner hot oil would find its way to the road.  To check that everything is in ordr, blow in the hose to the timing case, your breath will somewhat easily exit out  the larger out let. You might be able to get away with automotive  PCV valves, though Bunn does not reccomend this,  I have not tried them.  I am very happy eith the Bunn set up

Bunn Breather inlet... without the filter you can feel air being sucked into the timing case, at the exit you will feel puffs of air coming out, if ther is oil coming out, stuff more window screen in the clear tube  exiting the engine...first photo
