About 90% of the bikes seem to do that so it isn't necessarily something wrong 
It is more than likely the thrust bearing nut that unfazed mentioned in this thread http://foc-u.co.uk/index.php/topic,12149.0.html
It would probably be worth doing a quick search as there is a huge wealth of information already covering this topic
If the feel of the clutch is fine, adjusting it won't really do anything. If you are determined though, first stop is to remove the clutch plates and check them and the basket for wear or anything obvious then pop them back in - take note of the order as you remove them! You don't have to drain the oil, just put the bike on the side stand and you'll be fine. You may however require a new clutch cover gasket as yours may have deteriorated over time YMMV
