It's working as intended. But I don't believe it is a worthwhile mod given the hassle of of emptying the collector jar every couple of hundred miles and how little oil gets into the the intake (I allowed the oil froth to condense down for a few weeks once it was full and there was only enough oil to cover the bottom of the collector jar, so just a few drops-after 200 miles of running)
I will likely remove it when I do my winter engine service, as I'm not a fan of complexity with no purpose. So my conclusion is there is no need to second guess the S&S engineers when it comes to crankcase ventilation, as their solution works just fine.
That is why Morgan Custom is working on separating in the tank.
