Anyone doing the breather bypass on your M8?
#581
I did mine today with a Ventilator air cleaner on my 19 SG. Easy peasy. 7/32 tubing, 2-5/8odx3/8id grommets, 1-3/16 tee connector, zip ties.
Drilled 2-1/2" holes in the backplate. Insert grommets and tubing, connect to the tee behind the air cleaner and run one line to the ground. Tubing fits nice and tight to the breather bolts. I think I will add a small filter at the bottom. There's no room for a catch can centered under the air cleaner like I put on my Twinkies.

It is not the only way, but it is the easiest way.
LINK to some options.
LINK to a step by step with lots of photo's.
Actually, the easiest is to sell the BS and get an Air Cleaner System that is designed for, and includes, an External Breather System, like seen HERE. Might even be less expensive if you can get most of the $ out of your BS A/C on ebay.
It will certainly be far less work, and be a better system.

For some reason I'm getting oil seepage from the bolts. Everything is snugged up, but its really sucks getting oil spray all over my exhaust and saddlebag.
Any help is appreciated.

I had mine rigged like that, it would not blow the stuff up & out. so I turned my t fitting over to the downward direction & rerouted the hose & all was good

Breather hose/plugs Screaming Eagle Round Filter
Hi, does any know the part number for the Screaming Eagle Round Filter breather plugs/hoses? In this setup the round filter sits on top of these plugs/hoses. I'm crafting a bypass for this setup, but need extra plugs/hoses to work on, don't want to mass the only ones I have. Many thanks.

I don’t know if the washer fluid hose you are using is oil resistant - if not it may degrade. I use fuel line on my mods. Any auto parts store sells it by the foot. 1/4” ID line should fit over the breather nipples. You can always dip the end in some boiling water to soften it up, then push it on while hot. When it cools it’ll retain the shape needed.
This is 1/4” fuel line from two SS barbs threaded into the standoffs. The internal vents were filled with permatex ultra black. I used to tap and red loctite set screws into the passages, but decided while red loctite will never come loose, it was safer to use RTV then little chunks of steel that close to my intake...
Edit: Crap. What I was responding to was posted back in July. I’ve become what I hate...

Air cleaner mod
After banging my leg on the K&N cold air intake, I decide to go a different route with the ventilator extreme Screamin eagle. As always, there are a few ways to do the breather modifications. I found some 90 deg bulkhead barb fittings, and ended up utilizing some of the stock breather components to make it work. The nuts that secure the barb fittings are on the back of the air cleaner secured with copious amounts of lock-tite as well. I also used silicone fuel line for the hoses which are joined with a brass t and sent down under the bike along the frame rail and then down to the ground.
