Default 2012 Sportster 48 breather mod

I used parts I got from ACE Hardware and hose from a local bike shop to do this mod. I drilled and tapped holes as you see in these pictures and used gasket sealant to plug the stock breather holes routed to the intake. The brass fittings are 3/8 in hose barbs. The catch can I got is from Denniskirk.com

I have ridden 120 miles or so with this setup and so far so good. The can is very well built.

So far no oil collected yet. I may have to ride it a few hundred more miles and see what happens.
