Many people say that changing the oil and the filter after the first 50-100 miles is a good idea. I say why not? Oil and filters are cheap and easy to change. Don't let your local dealer make you feel stupid when you ask these things. Actually many of them, know less than you do.
Oh, and another point...don't torture your bike just because it's past the 600 mile mark. Take it easy. One step at a time.
