For those with pods - what to do with breather hose?

Well - what do you do with the valve cover breather hose if you don't have an airbox to plug it into?
 
Make a longer hose and run it down where the battery vent hose exits in front of the swing-arm.

Jimmy, I put a breather filter on I got from Supercheap and cable tied it to the frame under the fuel tank.

That will keep the vehicle police at bay as it doesn't vent straight out onto the ground, and I have definitely noticed a few drips from it after riding, so best to make sure if you vent it somewhere without a filter that it isn't directly in front of the rear wheel :eek:
 
Why? Eventually it will become saturated and be really messy.
Nope. The engine is fresh and has no blow-by. If it does get saturated I'll just clean it. I've been cleaning K&N filters for decades. I hate oil drips on my garage floor.
 
The "correct" thing to do is to run it to a small catch tank that has a side connection for the line & a top vent for fumes to escape...

Something like this... but good luck finding one small enough. I have mine routed under the seat to a K&N style filter that is held in a small pot (actually a paint can lid). I put towel in the pot & replace it every 6 months or so.

So an old coke can with the filter jammed in the hole on top and your breather hose going in the side would work like a charm then ;)
 
I run one of those cans on my turbo car because I run 14 pounds of pressure.
Mine actually sticks straight up under the tank, so if it did ever start it would drip back down into the valve cover (this is the GPz).

Yep. I've not found anything off the shelf for our size but with a bit of creativity...

My friend used to run a Fosters can on his VW... (because he's tight ;) ) :)
 
Pete, please note the commercial product has several features lacking in a coke can.
That one has a sight tube on it so you can tell how full it is.
They normally have a tap near the bottom so you can drain the fluid.
They come in all sorts of configurations and colours, that one appears to be aluminum, but they also come in plastic.
They have a breather with a filter on it.
Personally, if I were to do a can I would purchase one similar to that and cut it down and reweld it. Much better IMHO, and I use one on my car.
 
run it down and point it at the top of the chain where it enters the sprocket cover. cable tie it there ...any drips go onto the chain and keep it damp depending on how much blow by you have. My motors fresh so i get very little...seems to do the job though ;)
 
I Will try a Hayden crank vent plus sometime in the future. Right now there is a K&N on the end of the vent hose.

That was most definitely a tongue in cheek comment :p

I would actually like to do something like that on mine because I'm getting a drip or two from the filter which drops on the back of the crank case and it looks like a few have blown back onto the battery also. If I do something about it, it will be a while away though, other things to do first...
 
Actually, it was not Pete. I have one of those on my turbo car and it is excellent. At 14 psi, or 2 atmospheres, it needs it. And the folk at the strip frown on cars that drip on their track.
If I were to implement a catch can that is what I would do, it would not be that difficult.

Sorry, I meant my coke can comment was tongue in cheek, not yours :)

If I was going to do it, I'd do the same, it could be made into a design feature of sorts if done right too...

Here you go, a genuine aircraft air-oil separator:

And this is the cheap one for non-certified aircraft! ;)

Oh, missed that.
I wonder if there is a market for one for a motorcycle?

There would be... although I suspect there would be such a difference in requirements in terms of shape and size that it may not be a worthwhile business interest as that would drive production costs up dramatically...
