Ride it fairly easy for the first 50-100 miles. Then make sure you vary what you do. Go short Wot runs and followed by easy trail riding. By 300 - 400 miles you're good to go. If you baby it like some tell you to you'll burn oil later.

You can switch to synthetic after 500 miles, it will be fine. It might take longer for the engine to fully loosen up, but it wont do any harm.
As for the correct break-in riding procedure, just dont run it wide-open for prolonged periods of time for the first 1,000 miles and you will be fine.
Some say, "break it in hard if you plan to ride it hard", but I dont believe in that.
