Oil leak? to worry about or not?

[Bones]

Firstly I don't like starting new threads, I have searched for an answer but can't find any like mine..
So after having a go down the lane on my bike yesterday I put her in the shed on the stand. After work today thought I would go and change the rear brake caliper, but there was Oil in a puddle (albeit small) on the floor under the head, on closer inspection it seemed to be coming from the exhaust valve, seeping its way past the tappet cover. Anyway I got new covers and seals today so have fitted them. Fired it up n let it warm properly, No blue or white smoke, no oil leak.
Just been back in the shed and there is another small puddle! I cannot work out at all how its coming out of there, even put a little hylomar around the tappet cover seal now and drained all the oil. Don't really want to waste more oil overnight
Found lots of threads about it coning from the exhaust port but all of them have blue smoke too!
Any ideas?

clean it all off & warm it up on a stand then youll see where.

OK thanks man, I'll check in the morning, don't think the neighbours would appreciate it now! The lower tappet cover was filled with oil annoyingly it runs like a dream for once lol

Right so did what you said JordyRoo, no oil leak when its running but when I stopped it tappet cover was full of oil again, no oil on the floor yet though. Looking at another thread it mentioned that you shouldn't put a tappet cover with a breather on the bottom as it will leak so I am going to take it as nothing to worry about, bike runs fine and there is no smoke, just have to keep an eye on my oil
