on top of the crankcase is the body breather ,(chrome dome) which has a pipe that feeds into the air box, i have K&N filters so i have added a pipe which feeds up under my seat into a small filter.
I noticed a lot of smoke and burning oil smell from there the other day, and around the chrome dome it is damp with oil. i removed the body breather today and there is a pool of oil sitting in the recess .
is this a sign of a problem or start of a problem. bike is not burning loads that I have to keep topping it up,

you need an oil catch tank -

smoke or vapor? smoke means rings are suspect vapor is normal. yes you will find oil under the breather cover

I route mine to underneath the motor (away from the back tyre). No smells, no smoke, no oil drips

need to do a leakdown test paul

+1 Excessive oil and burning smell from breather sounds dodgy to me

Oil in the dome don't worry, Zeds with higher mileage prefer not to be filled up to the high mark especially when ridden with vigour
