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.
I’ve looked around the forum for answers but only found this, apologies if it’s 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

Thanks Oz, didn’t see anything like this on my 2016 but appreciate the reply

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?

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.

I get a fair amount of oil in there. I spend a lot of time in the upper RPM range and frequently hit the rev limiter. The stock filter stops oil, the sprint does not and collects on the dirty side of the air cleaner. Remember this oil system sprays oil all over, so the crankcase breather air has a ton of oil in it. It is good to have that oil mist on the impeller. I keep mine between the high and low.

Interesting that the stock filter stops the oil leaking Ted, I’ll replace the OEM item and see what happens

I’ve taken 100ml out with a syringe and pipe, the level now sits halfway between the top and bottom as per service manual.
As per my reply to Ted, I’m removing the sprint filter and re fitting the new style “red” OEM filter supplied with the 2019.
I’ll keep you all posted, it seems to be an issue more people are reporting although it appears to be “designed” into the bike.

sounds good.I think you'll have no more issues with oil in the filter.Mine hasn't accumulated any oil in the filter intake or anything since i've had it.I always keep it in the center of the sightglass.2015.And i've taken her up many times at full throttle and kept it there for at least a half mile.I have the sprint po8.But with the stock filter,it still remained dry in there.Yeah.A teensy bit of oil residue in the endpipe before the filter.But she certainly wasn't 'blowing oil'.Never any at the catch tube.I also have a filter with a red medium in it.Supposed to be cleanable...but it has to be reoiled everytime.I don't use that one anymore.

"it appears to be “designed” into the bike."..IMO,no.It probably shouldn't be allowing oil to enter the combustion chamber.(the design).I think it's just people running high revs and putting too much in there,even if they're stopping at the upper mark.It says as you know...'between'.That COULD mean anywhere in between.But my first thought when I read the manuals(14's and the rest)I took it as in the middle.Could be wrong.Mine's fine 'in the middle'.You're not adding oil when she's on the rear stand are you?That'll definitely throw off the oil amount in there.

I remember now i actually did add too much...just at the top line one time(standing vertically).When i took her out,the shifting wasn't smooth like before.I drained some out,shifting went back to being smooth.

No effect on performance whatsoever, like I said previously just the mist of oil.

Loads of cases where this has happened to other bikes (and filled the catch tube)

If you read Ted’s post (above) he has it every time too, maybe it’s more prominent on the newer H2’s as my 2016 never did it, even when revved to 14k. The oil was always there or thereabouts on the top indicator with that bike too.

I’ll see what happens, it’s not making any difference to how it rides plus lots of people with both H2 and H2 SX are reporting it so I’m unconcerned.

Regardless, I’ve told the dealer and will drop it into them in a couple of weeks after more miles

did they do some slight redesign to the motor?I thought i read they had.MAYBE they did something to allow a small amount of oil to coat the filter?It seems odd that so many would be doing this particular thing.
