I'm looking at installing an external breather system such as the one you have on your 2014 Tri Glide. I have a 2016 Tri Glide, which external breather system kit are you currently using and would it work on my 2016? Photos below of my Screamin' Eagle Ventilator.
To the OP, on my 2009 Electra Glide Ultra Classic I had a external external breather system similar to what Fearless is running and I had a catch can on the right down tube.
I would drain the catch can every month.
I used RTV to plug the holes filter where the stock breather hose went, never had any problems.
With my 2016 Tri Glide I'm thinking of going with a setup like what Kevin is running, looks very nice.
