Breather /Crank case venting
#12
I have a similar air cleaner from S&S where the breather and banjos were integrated in the backing plate. All I did was cut off the flanges, plug up the breather holes in the backing plate that remained with a small piece of wire and silicone, and a little black paint to touch up. Came out perfect and the modifications cannot be seen.

Copied and pasted 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.

If the filter gets saturated it will drip, Amazingly enough using a vent hose to a can, or a filter, or to the ground produces less oil and mist than you would get venting to your intake due to the suction of an aftermarket High flow intake pulling on the breathers. "Venturi effect"
