Behind the ECU cover on my '12 1199 S. Noticed this hose is completely cracked/Leaking. I'm not too concerned because there's no gas or coolant - I'm assuming this is a crankcase vent or something. Anyone know?

just FYI...

...i cannot say i know the hose....i rarely look under there....but: the older style crankcase breather tubes now connect to the bottom of the air box, and if this is in fact that hose that then goes to the bottom of the fairing, you would want it in good condition....as there has been a piston cylinder sleeve defect that pushes "copious amounts" of oil up and out thru the crankcase breather, into the air box...then it drains out of the drain hose (usually when parked on the side stand)

It's the fresh air valve. The hose goes to the check valve down to the side of the head. It's on both sides. You can buy the block offs for the heads and cap the valve and never worry again.

Thanks for the info. I'll trace the hose and see where it goes.

ducati omaha has the parts diagrams on the website:

the one on page 51?

My photo is on the right side - I believe it is hose 21 in Drawing 018.

Thanks! I suspected it was something like that. Excuse my ignorance, but which end am I showing in my picture? Side of the head or the check valve?
 
The pic you posted is the valve at the airbox. The other end of the hose has a simple spring clamp holding it onto the cover of the check valve.

You the man! Thanks bud.

So stupid question time: why do I need to do anything? Any air taken into the airbox (through the broken hose) will be filtered by the filter. The check valve will basically not be operational because of the cracks in the hose - no pressure fluctuations seen by the valve (as would be the case with block offs).

Am I missing something?

The valves in the heads allow fresh air to flow through the exhaust without passing through the cylinder. Airbox won't be an issue but if you start getting water and other debris into the cracks it will go through valve,head and exhaust system. Your call. Just giving you info.

Oooh got it. I will block it off then, obviously! haha. Thanks again for your help. If you know of any off-the-shelf block off solutions available, please link me :)

Otherwise I can figure something out.
