There is no real published break-in procedure.
The high temp is a concern. This can be caused by low fluid level, reduced hose radius (common) when it gets warm that slows flow, a large section of air in the system or
an over pitched prop. If you are using Evans coolant this will cause the over heat. Use 50/50. If you are using 50/50 coolant don't go over 248F.
Think of this engine as a motorcycle engine and not a loose tolerance, air cooled Cont. or Lycoming eng. When you buy a new motorcycle you get on it at the sales center and ride it home. If you buy an ATV you take it out a ride it. It was run at the factory for a short time. Let it warm up well for the first flight. During the first flight vary the throttle some. Make sure you don't have the prop pitch set too course so it won't over stress the engine components. Take off rpm can vary some, but right around 4850-5000 is pretty normal. This should give you at least 5500-5650 WOT flat & level rpm.
Check fluids and looks for leaks after landing for the first flight.
Make sure you register your engine with Rotax and make sure you do the 25 hr. Rotax warranty inspection which includes an oil change. Make sure it gets logged in your logbook.
Most of all have fun with your new plane.
