Dick,
I wasn't going to correct you because I don't have access to documentation at home, and couldn't remember if there was a 500 hr overhaul.
But I do know that the 200 hr interval isn't a requirement for an overhaul.
It
is a very thorough inspection though, but only requires replacement of parts "on condition".
The full blown overhaul kit retails for about $500, but it shouldn't be needed until the engine has a lot of time and years on it. I think Rotax recommends that you need a service parts kit (about $150) to do the carb. inspection. With care, you can disassemble and reassemble the carbs. without it (many Rotax techs do so).
My experience has shown that the highest wear item in the carbs is the float arms, as a result of the float pins rubbing on them because of engine vibration. Fortunately the are not super expensive.
I believe a dynamic prop balance goes a long way towards minimizing this wear.
