Air hoses - oil?

Looks like the end of the hoses from the air box have one with, what looks like, engine oil to me and one clear... Any ideas? See pics

The reason I guess engine oil is because when I checked the level of engine oil after the dealer replaced it for the first 1000km service I noticed it was well above the max line in fact it covered the whole oil glass Finder.

Would this change the idle of the bike?

I will be checking my air filter to see how that looks but that involves removing the fairings

Looks like EGR pulled some oil into the filter box. Hope nothing else goes wrong.

Crankcase ventilation will cause a very small amount of oil back into the air box.Overfilling the oil will create more.
Just remove the end hose caps and drain the hose.
The other clear hose is for a water drain.
No need to remove fairing for filter removal.About 4 or 5 bolts give you enough room to remove your intake tube,then your filter is easy to get to.

I had the same thing with my bike. A guy from Kawi came to my local shop and took my bike apart and found no oil going anywhere else. The stock oil filters have oil on them which could be part of the oil in the tube as well.

Guys, quick question...
Has anyone found a misting of engine oil from the crankcase breather Inside the air filter housing?
Mine was coated, not pooling but enough when cleaned I could see the colour of the oil on a cloth.
Iíve looked around the forum for answers but only found this, apologies if itís already been answered.
There are a few cases of this on the SX forum and the general consensus is that if you over fill oil then hit hig RPM the crankcase ejects the oil.
Mine was slightly above the upper line on the oli level window, looks to be over filled, annoying as it was done by the dealer...
appreciate any feedback

Pretty normal, over full may contribute but its an area that will show varying degrees of oil vapor misting depending on your riding

if it's completely covering sight glass,I would definitily drain the amount out to get it where Kawi says to have it.Running overfilled is not good.It expands for one thing.Then you can get foam in there.Which affects the viscosity.Not good.I'd drain some out.You'll see your other problem vanish.You can probably leave the filter alone and let the supercharger pull the remaing residue on through.That will work okay.Can you hear anything sounding 'off' when she's running?Missing or stuttering?Holds idle okay?

No itís just on the top indicator line, maybe slightly above when on paddock stands. Engine perfect in every way, just the mist of oil inside the air filter box.
Dealer informed, loads about this on SX forum:

Well...that's okay...i guess.Manual says between the upper and lower marks.I think ya still have too much in there...but that's just how I do mine...how's it shifting with that amount in there?I know on my 14 when i once overfilled it it started shifting badly.
