Yeah I agree with that. I varied my rpms as much as possible...and kept it under 4000 for like 250 miles..and after that, I started beating on it, lightly at first. And as I passed 500 miles, I basically started riding it like I ride it now. Hard at times but usually nice. But I wasn't afraid to open it up...and it runs great right now.
The one thing I would note is, engine braking. If you rev the motor up, don't pull the clutch in early. During break-in...let it coast down in gear. Something about the piston rings, etc don't wear in properly if they climb up the revs, but aren't allowed to pass down them under load as well.
