how to break in after rebuild?

So I just bought a 2004 honda foreman 450es. Lovin it sweet bike. But the top end was just rebuilt. I’m wondering how to break it in. I’ve seen the two different methods easy break in and hard break in. I was thinking I’d go with hard break in. But the motor already has 2 hours on it so whatever was going to be done is already done. So what should I do?
Thanks.
