Oil Breather Hose upgrade - Ducati.ms

BKK · Dec 27th, 2011, 4:46 am

I was looking at that oil breather hose today thinking....Someone must make a Stainless one....Something better looking then that big rubber hose.

Anyone have any upgrade suggestions for that hose/breather?

How about some reccomendations on GOOD hose fasteners? That stock one looks like the kind you buy at a hardware store for 25 Cents.

Saw some pics on the monster forum of people just eliminating the hose and putting a small filter on top of the breather.

Do some research on this. The oil breather is a source for oil spew when doing wheelies. There are extreme cases such as Jason Britton (Superbikes) wheelying long enough to fill the airbox enough to ingest the oil into the cylinders and cases of others with just the K&N filters on the breather spewing oil down the backside of the motor.

My opinion, use a billet breather with a hose that runs up high enough toward the steering head and capped with a K&N Filter. This will put the filter up high and forward and out of sight/line with anything that would be detrimental if it got oil on it/in it (such as a rear tire/airbox).

That still leaves you with finding a more asthetic hose/clamp set-up, but at least you will avoid to oil leak issues.....somewhat.

Pep Boys, Auto Zone, etc., most sell braided stainless covers and ends in all different sizes, to slip rubber hoses into, making them appear like Stainless.

Try to put the clamp mech towards the cylinder jug. Then tighten it from the shock side. You would be hard pressed to find someone on one knee with their nose against your motor to complain about how it looks then.

Abarth should be able to help you out, he has an alloy breather

Yes! My hyper finally arrived!

Ya I just did that trick tonite! It will do for the interim until I find a better solution. Thanks...and thanks everyone else for any input!

An alu oil breather is just eye candy.
But if you combine it with a filter from K&N you will never have a foggy oil checking glass again.

But don't put the filter directly on the breather, because it migh cough up some oil. Mine is connected through the stock hose to a K&N filter up high in the frame to where the airbox used to be.

Abarth,

could you explain to me why the condensation is reduced by altering the oil breather system? Where is the condensation comming from?

I personally think that the best setup is were the crank case is actively "vented" off by some sort of low pressure suction line.
I have seen some bad results with cars with no or malfunctioning breather systems (black sludge).

I do like the bling on your bike, should do another meet and greet in 2012!

With the stock setup the oil breather vents inside the airbox which in essence is still a closed box. Which makes sense, because in the airbox there is always a small vacuum and plenty of room for the oil spill to go. I guess with the stock setup bigger tempature differences occur sooner between the air in the oil checking glass (because of the more closed off environment) and the surroundings than with the setup I have. (which vents with it's own filter directly in the open air).

And, yes I agree. We should definately organise a meet and greet with all Dutch Hypers.

If the case venting is working corectly it will have no difference on the condensation problebm no matter where its located, the milky sight glass is caused by the cold conditions creating moisture in the oil, and will go away when the motor get hot enough to evaporarte the moisture.

On a stock bike the breather is in the airbox due to emissions, so the oil fumes will get reburned. There is no real vacume in the airbox due to airfilter, but enough to draw in the oil fumes under hard running. Aloha Alex
