In all the discussion about pods installation no mention was made of the need to install a crankcase breather filter as well. Are these somehow plugged into the breather hose and secured somehow?

I have seen two methods used.
1. Run a longer piece of hose back, then down to where the other drain hoses are. This is much like cars used to be before implementation of the PCV systems.
2. Go to the tuner section of your auto parts store and get a breather filter. Looks like a little pod filter for the carbs. These are usually available in a selection of colors.

or add a catch can so you dont have oil spewing all over. The breather filter will spit out oil.

So, as I understand it, in the stock airbox setup the breather hose goes back into the airbox and then the airbox has a drainage hose out the bottom. Then in the case of the crankcase breather filter addition where the airbox is removed, some of the excess crankcase oil would come into contact with this aftermarket filter. Why is a filter suggested and available-wouldn't it plug with oil after a period of time?
Environmental concerns seem to be ignored in either approach as they probably were not in effect in 1981. Therefore, why not just have the oil drip out the hose, a task formerly done the same way out of the airbox? Or is it a two way thing-oil can drip out but a vacuum can suck air back up the tube and therefore a filter might be helpful?

Shoot in that case just run it so it drips on your chain.
If you have one.

I'm not a motor guy, but I've read in these forums, that it is indeed a "breather" hose. It expells gases from the engine and also intakes a certain amount. Therefore the need for the filter, so road grundge, grime, dusty bits, etc.. doesn't get into the engine.
I forget what I was searching when I ran across that...exhaust something or other, perhaps.....:-k

No-its shaft drive-a 650G.

That's my understanding as well. I can see the need to filter incoming air that will eventually reach the engine, but I can't see how the drips of oil going out wouldn't contaminate the added-on crankcase breather filter, unless it has a drain built into it for that purpose-I've never seen one up close.

You dont really need a filter on the breather hose. Theres already a metal screen in the valvecover. I think the filter just looks better than a hose venting to the atmosphere.

That's why I just ran a longer hose down to below the swingarm on my son's 650L.
Already had the hose, and I'm too frugal (cheap) to spring for a fancy little filter.

From the thoughts expressed here I'm beginning to believe that the add-on crankcase filter is a bit of a doodad that may clog up and interfere with the escape of the few drips of oil. However, the air that is drawn through the tube and into the crankcase would not be filtered, whereas in an airbox situation it would be.
The question now arises as to how much oil out and how much air back in is involved. GS machines are known for losing some oil between changes, even when relatively new. Does this oil pass by the rings and/or valve guides, or does a fair bit of it escape from the crankcase vent, I wonder.

Id say you will probably always have gases being vented out of the breather rather than air being sucked in. The blow by from the combustion chamber build's pressure in the crankcase. Therefore you will always have the gasses being vented out of the motor.

Steve's #2 option is the way I went, got this guy for $6 at a VIP Auto store.

Not worth worrying about!!

As an old HD guy, I think the best thing to do is route the tube where it makes the least amount of mess (almost zero) and forget about it...I don't think the bike will last long enough to where anything sucked in will make even the slightest bit of difference. I think those little filters you can put on are a gooey, gimmicky mess that won't make a single bit of difference in the life of your engine (until they get clogged up with road grit..which they will, if they're on the underside).

That's what I was thinking but you said it better.
I think that tube is going to go where the airbox drain would have been and have done with it.

I used a K&N crankcase filter and ran it back to a catch made from a paint can lid strapped to the frame. The little bit of goo that accumulates over time can be wiped out.

Crankcase oil venting
Crankcase oil venting
Guys; I have pods in my GS1100E and a breather venting hose directly down to the atmosphere routed with all hoses. Honestly, I've never seen any drop of oil coming out of that hose, being more specific, the hose are completely dry. You have to remember as said before by another member that the valve cover already has its venting route an oil trap, also remember that once oil is trapped and separated from outgoing venting gases it is heavier than air and it will drop down to the engine again, so, that's why you should not be worried about a breather filter or whatever stuff in the venting path, just route the hose with all others.

My bike pukes a little bit of stuff.... this stinky slimy oily watery stuff. Being the clean freak that I am, I chose to catch it instead of having it drip down anywhere.

I run a filter and the oil trap in tha V-cover does its job well enough I don't get any spooge coming out the filter.
Think about this, the pistons and rings have a good seal in the cyl.'s.
When the piston comes down it will compress the air under it in the cases.
When it goes up, there will be a vacuum under the piston. If this were not the case we prob. wouldn't need crank case breathers. If we don't have a breather or its clogged this pressure will blow out seals.
Diaphram type carbs and fuel pumps operate off these pressure changes on some older engines.
Some modern and or performance engines increase ventilation in order to allow the engine to rev more freely with less resistance,up and down, in the crankcase.
This is why I vote for a filter. Also why the factory has it routed to the air box to breath clean IMO.

If you have oil coming from the venting hose, that is a warning of you most probably have worn piston rings which produce high blow-by that pushes oil up to the engine vent system vent.
