[size=1em]That's normal on the oil cap, it's a by product of cold weather and short runs.[/size]
Happens to my bike every year and is completely okay, albeit very worrying the first time you see it. A bit like when people suddenly think their exhaust is chucking out smoke in winter too, when it's just hot vs cold.
It's to do with the bike not getting up to full operating temperature and burning it off so it's a mixture of condensation and oil.
It's also one of the reasons why you shouldn't start a bike in cold conditions in winter just to turn the engine over as this will happen.
As Red says, either go for a long run, which you don't actually need to do, or just wipe the cap off and put it back on and pretend you never saw it.
When the weather warms up it will all disappear like a bad dream. :look
More people are born because of alcohol than will ever die from it.
