Good choice of bike - don't forget to vote for it!
There's a load of info on this site as to how to tune your bike, and modding the airbox is a good place to start.
You will probably be okay for jetting if all you've done is the box, but to be sure you really should pull a spark plug and check it's colour.
Best bet is to surf the site and read all you can. Then if you have any further questions get back on here and give us a shout.
