oil on plugs

[91cb-1]

Hi folks, changed all plugs fork oil, pads etc. on removal of plugs 1 & 2 from left to right plug 1 had a tiny bit of oil on the tip of the plug plug 2 had  oil where the threads end going into the head. there's also a very slight ticking from left side of engine on acceleration, not on tick over though. Am i looking at valve tappets or something more sinister?

if the plug colour is good (not black) than I wouldn't worry about it too much. haven't got mine running yet so no idea what sounds are good/bad
