The standard Gen1 thou runs on the lean side.
However standard air boxes are seldom capable of flowing more air than they do with the OE filter, so fitting a K&N should make no difference.
One of the best mods you can do to the bike is to 'Ivanise' it by the way. And of you have a K&N plus aftermarket can you really should. The 'fully monty' Ivan's kit include a wee mod for the airbox so it'll flow more air with a free flow filter like your k&n.
