The first service really is about changing the oil and filter, as a new motor is breaking in or wearing in new parts which causes metal particals of metal to wear as it runs in so the first 500 miles is where most of the metal particals from the rings bedding in so its important to change the oil and filter from that run in period to get rid of the those particals from the rings bedding in.
If you can't get to your dealer at that time or a little over but not to far over do the oil and filter, its the most important thing to do as part of run in, all the dealers do is oil and filter, the rest of the first service is to go over the bike to make sure nuts and bolts are tight, adjust cables for any slackness and to make sure everything is right and things adjusted right, test ride it to make sure things are smooth and right.
Doing it yourself does not affect your warranty as long as your record it in your service book that its been done, you don't need your dealer stamp in your book to effect your warranty as long as its been done.
My dealer has no problems with me doing my own service as long as its beeb done.
