There are so many ways to get to the same results. Another reason I built my own (besides wanting brass) was that I wanted to use 1/4 fuel line instead of 3/8 just for a little 'slimmer' look.
Now a Brass CatchCan to match the Breathers

haha Yeah. I'm more of a function over form kinda guy. I don't care if it is ugly as sin as long as it does what I want. No good having a bike you don't want to ride, whatever that may be. I appreciate the mechanical and design behind everything.

Thanks a lot. I used a small clip similar to this to secure the 'T' fitting to the back of the air cleaner. That secured it pretty well. If it doesnt hold up, then I might make something stronger.

Nice job,I still think I came up with one of the best/cleanest looking,invisible mods so far.If I do say so myself.
Copied and pasted my solution from one of the many threads about crankcase breather venting.
This is what I came up with after being unable to find any system that would work with a SE stage one backplate, I went with dual hoses parallel to bottom of rocker box covers then down to hidden catch can in cowbell. Marine shrink wrap over fittings tapped into backplate really cleaned it up.
This is why. I didn't have a lot of oil drippng, But enough to make a mess on cam cover,pipes,side cover,and front of saddle bags if I didn't clean the filter every week or so. It looks like this because the moisture and oil are being shaken like a paint mixer in the cowbell. Glad this gunk isn't going in my intake.

I've been planning something similar, though instead of a simple screen I'll mostlikely be utilizing the brass wool that's found inside the compressor oil storage tanks of the Cleaver Brooks boilers, for inside the canister [the likes of which will be revealed sometime in the near future], to attract and hold any oil vapors and to allow any accompanying air to escape to atmosphere.
Great job!

Great thread! I've been thinking about how to do it with my SE backplate. I don't want to change my filter to a smaller one so I can access return lines. The cover is a custom one I made and don't want to change it. I guess my question is realistically how big does the collector can need to be? I do think you need one but seems like some of them are rather large. How often do you find you need to clean them out or change the oil absorbant material?

BTW...my wife claims she can smell it when we are in traffic. My drool cup with vent is just behind the left passenger foot board. If this becomes a problem, then after the trip I'll move it more towards the back.
Our last local ride, the oil got pretty hot...~250...and I could actually see a few whiffs of smoke or steam..coming out of the vent. At least that means it is working.
The best part is no more drool coming out of the open AC, getting on the engine, exhaust, and my wife's jeans!!!

I've Let it go a little bit longer between each drain. at 1k miles now without much more than in the photos.
The thing is with the vents going into the breather, Your intake air flow,Or negetave pressure actually increases the amount of oil sucked up out of the crankcase. The venturi effect. So with a catchcan or just a drain its not being pulled out just draining what the vents push out. What supprised me most was how much water vapor condenses in the case, Of course we have 99% humidity most of the year here. So its good to get the oil temp up over 220 and ride a while to get the steam out.
