Thanks in advance for any and all input. I've done a lot of reading and am searching for any input like pics, specs and ideas on how to do this right the first time. Pretty sure I am going to use my buddy SBates idea of the Rushmore breather parts. Again, any and all input is greatly appreciated.
Bike info: 2008 ultra E glide with the Fuel Moto 107 and woods 555 cams. 2009 2-1-2 header upgrade with CVO mufflers with Fulsac 2 inch baffles. And of course an Arlen Ness big sucker A/C.
Pretty sure that's the pertinent information.

1st is to run the oil a pint low.

this has worked for me for over 100K on head breathers.

or if you insist, tucci's thread is pretty good.

Thanks Mike. I agree Tucci's thread is a great source of info.

I installed the A/N Big Sucker, and keep the oil level about halfway in the etching (Pint low, like Mike said), and no more drips here.
I still use my stock air cleaner. I developed the habit of when I stopped for fuel, I would take a paper towel to wipe the oil off the bottom inner lip of the air cleaner cover. Since the Big Sucker and the lower oil level, there is nothing there to wipe.
It worked out good for me.

 

It doesn't matter whether you run the oil level low or not you still get oil residue sucked into your intake which turns into carbon build up on top of the piston. Just because you don't get the oil slobber doesn't mean this isn't a good idea to route it to the ground. The new Rushmore breather tubes make this easier than ever. Use the stock breather bolts, or for the thicker backplates the Kuryakyn breather tubes that are 1-3/4"(9976) long will work. Using the Rushmore breather tubes makes it easy to add extra hose and route it any which way you want it to go.

Carbon build up.

Would like to know the partno's for this easy fix. Thank you.

 

These are the biggest reasons for doing this little DIY upgrade. The stock 96 inch pistons I removed when doing the 107 build were like the ones pictured, and my new ones are sure nice and shiny.
Thanks again Bates. Looks like a foot of snow Saturday, so maybe I will start the process then.
Still not sure what bolts I need for my AN set up, but will for sure post pics and part numbers when I get it done.

Kris just measure your breather bolts. If they're 1-1/2" or shorter the stock breather bolts will work. If they are longer you'll need the Kuryakyn bolts part # 9976.
The part number for the Rushmore breather tube is 29400043-$12.29. Most dealers will have these laying around the shop from upgrades and may just give them to you.

 

Can anyone point me to a thread or report of an engine having issue or failing due to sucking in oil vapors? Serious question. I mean, cars have had this design for decades and I for one have 100k trouble free miles on my truck without bypassing the breather. Seems like a non-issue to me. After all, I highly doubt HD (or anyone else) would design a feature into their engine that would lead to problem that they would have to fix under warranty.

 

Nobody is twisting your arm to do it. If it's not an issue for you then don't bother with it. And just because auto manufacturers have been doing it for years doesn't mean it's good for your engine. I can assure they wouldn't do it if they weren't mandated to do so. Carbon build up in your combustion chamber is never a good thing.
