I've done a lot of searching but haven't found anything on what people have done with the breather hose coming off the head that went to the stock airborne after they went to a pod or cone filter. The old stock airbox had a lot of oil in it and the hose coming out of the bottom of it didn't have a drain hole for the oil. My old filter was drenched. Which probably was part of the problem of why the bike acted like fit was bogging down at wot. Anyway. I went with a pod filter. I live in Washington state near the Idaho border so it's pretty moderate here. Pictures would be helpful if you have them. Thank you for your time

The stock air box should have a hole with a drain tube attached (about 10” long).  It’s on the left side of the bike below the air box, behind the front pulley, and in front of the rear tire.  That’s usually where it is just hanging down.  I have mine tucked behind the motor and shifted towards the left side rear of the motor (there a hose/wire crimp clamp on the frame back there I used to secure it).  Maybe some California or European models don’t have it for environmental reasons.  I don’t know why you don’t have a drain tube.  

The drain tube can get clogged where it connects to the air box.  Crap accumulates in the bottom of the air box or a mouse may have built his winter home in there.  I had a bike that sat up for a while, and a mouse or some critter moved in.  Remove the hose at the bottom of the air box and clean out the exit hole on the air box with something like a pipe cleaner, small screwdriver, compressed air, and spray it out with parts cleaner or engine degreaser (shield/cover stuff you don’t want to get the parts cleaner on).  It can be a messy job, so protect the floor if needed too.

When I installed a pod filter, I just kept the stock vent hose attached to the stock air box.  The air box is now a giant oil puke catch bucket.  I check and drain the air box (oil catch box now) with the supplied drain hose when I change the oil.  Since I’m already down there getting dirty and intimate with an oil pan and the under side of the motor.

If you removed the stock air box when you installed your pod filter, you’ll obviously need a different solution like Dave mentioned.

My 5” UNI pod filter butts right up to the stock air box.  The rear side of the pod filter virtually meets up perfectly to where the air snorkel going to the carb used to attach to the air box.  I removed the stock panel air filter in the stock air box and removed the side cover of the stock air box.  This lets the pod filter get some air flowing into it from the rear and not just the sides of the pod filter.  It’s not ideal, but it’s good.  And I didn’t have to fuss with cutting up and fabricating the stock air box or removing it completely and it still serves as my oil puke box from the vent hose coming out the head cover.

I wish it was just vapors that convert back to oil.  These bikes flat out puke oil out the vent tube from pressure.  The harder you ride, the more it pukes.  Overfill the motor oil by more than 2-3oz, and it will really puke!

Sustained rpm in the upper speed ranges tend to create more oil blow by for the Savage.  If you stay below 60mph and ride casually there us very little oil that comes out the airbox drain.

Sustained interstate riding at 70mph and above with stock gearing - you better start checking your oil level frequently.

My bike used a little oil when my commute included 25 minutes of freeway riding.  My new commute is all "city" riding and it hasn't used a drop of oil between oil changes.  

Bohica, this old post provides all the details you need to make a breather system.  You have your filter clamped right onto the carburetor; do I have that correct?

If your filter clamps directly onto the carb, then there isn't any way to vent the breather back into the intake tract (like Dave's).  In that situation, a catch can/breather with a small filter on top is a viable option.  That's what this old post shows.

Paul, the setup you describe vents your breather directly to atmosphere.  Air goes both ways in these breather systems, out when the piston goes down, in when the piston goes up.  What you describe will result in dirt being pulled into your engine.  You need a breather filter on the end of the hose.

DBM - I have the stock set up with the breather tube from the head connected to the stock air box.  Yes, it goes to atmosphere, but the puke lives in the bottom of the air box until you open the clean out “puke tube”.

Yes, the oil vapors could make their way into the stock air panel filter (if you’re still using it) and ultimately make it into the carb and combustion chamber.  This is a very common setup for all sorts of cars and bikes.  Is it ideal, no.  Does it get the stock air panel filter a little yucky, yes.  Is it a huge deal, no.

With my pod filter outside the air box, there is zero chance of liquid oil getting on the filter.  The small amount of oily smelling air that the pod filter sniffs is negligible.

And I live in Texas, not LA-LA land.

This is what it looks like with the hose attached.
