Are you still smelling burning rubber (belt) or just that first time?
If not I wouldn't be too concerned, just use low when inching forward or driving at low speeds. The break in procedure is a heated topic, there are arguments to both sides. Unless you were constantly hanging off the rev limiter I really wouldn't be concerned with improperly breaking it in. In my opinion you should be more concerned with the diffs and gear box (trans). You don't want to be pulling holeshots or riding wheelies (with an ATV) on concrete or asphalt until the gear box and diffs get broke in and you do your first oil changes. Part of the reason for doing oil changes at 10 hours is to remove the wear material from the initial break in of the gear sets. Other than that I wouldn't worry. Enjoy!
