I have a 2001 426 and mine does the same thing so does my uncles(same bike) if its just a little bit it is fine as far as I know its normal you might have too much oil in there and just didn't notice the leak before but it will still do it even if the oil level is perfect

The last time my son came in from a ride with oil all over his left foot, it was from a fork seal. The breather tube is almost directly below you foot while riding, and doesn't blow a lot of oil onto one's boot, usually. It threw us off for a while, because the leak was transient, and had stopped by the time we saw the oil.

My 04 yzf450 has blown a little oil through the breather since day one. It doesn't amount to much, but occasionally it does show up on my boot.
