I just followed the sticker on the tank (my fave sticker ever!

) and rode as much as I could the first few weeks. Didn't take long to get to 500 miles and the first oil change. But I wasn't in a hurry, either.
There is a method of doing it using a dyno, which I'm told only takes about 45 minutes. Don't have it handy, but I believe it's outlined in Kevin Cameron's book "Sportbike Performance Handbook." I know a few racers who've used it on built engines and several street riders who swear by the dyno method. Might be worth it if you're really in hurry.
