Default External breather setup recommendations

I'm looking at running an external breather setup to keep that oil from going back into the engine, specifically on an S&S Super E. Post your setups, give me good ideas! Thanks guys.

S&sS breather kit for an Evo... It doesn't get any easier than this. And if you want really nice looking stainless braided hoses coming off of each individually the way I did it in my picture those are actually 3/8 braided lines for the toilet fill valves plumbing parts...

Thanks man.

That parts on the website looks like the stock S&S setup. Or at least what's on my setup. Looks like I just need ditch the center line, block the line going into backplate, and run the two breather vents down and T'd into a crankcase filter.

Well thanks for the guidance. Seemed pretty easy once I realized those two breather vents can rotate. Here's what I came up with with a run to the auto parts store. Probably a waist of thread but oh well

I use these breather bolts from Low Brow Customs.
Clean and simple.
I like the fact there are no hoses needed and the screens are washable.

I like those. I ran those on my sporty 1275 conversion and the only downside was the oil spray over the oil cover on longer trips. Looks awesome though!

The way I did mine was to get about 8 foot of 3/8th hose and a metal t junction.
I put the t junction between the breather tubes and ran the hose up to the frame and followed the frame all the way to the back of the bike.
Unless you know its there you won't see it.

Whichever method you choose don't forget to plug the original hole in the back of the air filter backing plate.

My 98 motor has a build list that says it’s “The Cure” breather kit was installed according to the build list it came with. Discontinued but works well. Found pic and it just came with a couple o breathers and two different sizes of drills.
