I might skip the stage I to put a different cam in right away. So far, I like the stock air cleaner just need a better breathing filter and a metal intake manifold. S&S Super Street exhaust is still at the top of my list and a Power Vision tuner I have. A couple of the new cams are interesting but I have time to choose when Winter is over and I can put a few miles on. I have put zero miles on the bike so far. Thanks.

Plenty of people do the breather Mod ,but i think a lot of people dont admit that they route the snot from their engines are they worried about warranty or the dealer telling the Moco to me its a no brainer first thing i did to mine was this mod

My bike is new now, I did the mods to a spare AC backing plate in case I have to change it back to stock. Once I get a few miles on the bike and change the tuner, exhaust etc., it won't matter.

Haven't ridden it yet. Hoping the catch can doesn't fill up to often or worse yet puke all over the side of the bike.

Nice job! I used 2 of those Golan Products catch cans, One on each side. They never fill up. They are pretty nasty when cleaned at each oil change. I don't top my oil up to the full line either.

Default External breather oil catch pan.

This is what I did. An external breather / oil catch pan.



Through the back of the airfilter backplate.

The oil catch pan with breather filter.

On the 107" Road Glide I plumbed up some fuel hose with a "T" within the filter assembly then drilled a hole accommodating the O.D.of the fuel hose in the back plastic part of the housing about the 7 o'clock position +/- and snaked a length of fuel line down below the bike.

No catch cans - works fine. The bottom of the hose and sometimes, after a hard highway run, a spot on the ground under the bike will evidence a tiny bit of oil.

Doesn't this mod defeat the purpose of venting the crankcase ?
