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
