You can tell if you are running lean by the condition of the spark plugs . If you are seriously worried about the problem I'd pull each spark plug, document their current condition (ie take a photograph of each) and then ride the bike till the next oil change or for a significant number of miles.
I would think a couple hundred miles would be too short, I'd say probably 1000miles and then re-check.
Just from a quick internet search, this website (Green Spark Plug Co (UK) Champion, Lodge, NGK, KLG, Bosch Spark Plugs) shows images of spark plugs which are experiencing different problems. Wikipedia also has some info on spark plugs which may help.
I must warn you, however, a spark plug job can get bad very easily, be careful to not cross thread or over tighten the spark plugs, for some reason the threads strip, the job will get a hell of a lot more involved and expensive.
