Default Rerouting breather line

I have a ‘97 with some work done to it and I notice I’m spewing a nice amount of oil through the breather and into the carb (S&S Super E) Just looking for some input on best option to just release it into the atmosphere and do I need to plug the hole in the carb where the engine breathes into.

Yes, plug the carb when you remove the hose. Get longer hose and extend down and to back right of vehicle or where best for you.

I've used 2, 24" x 3/8" stainless braided plumbing connectors for a sink and cut them to length to breath out the bottom just under the frame.. I'll dig up a pic and post later... They work great and look good.... Yeehaw...

And yes plug the port on the back of the airhorn..


this is the best pic I have..

The full mark for oil is too much oil, half quart low should be just fine.

How I've routed both of mine is put a short piece of hose from each head to a T fitting that is over the carb.
The take a long hose from that T junction and go up to the frame then forward to the down tubes, down the down tubes and finally follow the frame and have it vent next to the swing arm.
Unless you know to look for it the hose is practically invisible to the casual observer.

Thanks, this is pretty much what I had in mind, what did you use to plug the carb.

A regular automotive vacuum cap. Believe it's a 3/8" and use a small zip tie to secure it. AutoZone...... Or Advanced Auto.....

I had the lines going to a filter just under the aircleaner. Recently when I replaced my intake gaskets I installed the vented breather bolts and dropped the oil level.
No leaks yet, so it'll stay until it does.

Did same exact system and route. But they end at the bottom
of the left front rail.

I used some SS fuel line for my lines. I pulled it off a wrecked BMW and cut to length. So far so good.
