^^^ the 2k is based on Honda’s commercial grade engine. Questions about the belts have come up before but there arent many data points for belt failure. It seems that they hold up a very long time. Ive heard of utility crews using these things in the field with 12000 hours on them. At a thousand hours I’d be more inclined to check the valve lash, fuel lines, rubber bits, wire integrity, and keep on going!
