right hand side as you sit on the bike / clutch side at the bottom of the clutch housing youll see a big bolt with brass washer, thats the drain plug, lean the bike over if you want to get most of the oil out.

Above a little and back youll see a grey plastic thumb bolt this is the filler/dipstick (no dipstick as such just a cap) if you still cant see it, pm me and ill take a photo and show you. cheers
