I don't think there is a breather hose termination (other than a catch bottle) that will prevent the mist from getting on the tire.
As mentioned, there were 11 Vincents that had just completed a good run and all had the dreaded moist back tire. Two or three might have had tired engines, but the others were all in good shape. I'm not sure if any had reed valve arrangements.
My OZ bike has the Eddie Stevens well back and curved out twin SS pipe breather termination. This is designed to eliminate the oil on tire problem.
The SS tubes and mount look very nice, but there is still a little oil mist getting on the tire.
When all of the leaks are plugged, this bike uses very little oil.
At the end of a 2500 mile trip to California it required just 8oz to bring the level back up.
