Hey Doc
Not sure what your axe to grind there is, however I am reasonably informed by some locals down here that the good old 2-strokes are given a very low TBO for a good reason and Rotax do not refurb cranks and similar.
I would not say this is the case here because I do not know, but I would bet there are hundreds of two strokes that are touched up and flown well past their TBO just to save a buck.
Bit like some R22/44's that you get to read about from time to time.
I am not a fan of the two stroke aviation devices some folk use, and would be reluctent to fly one. Having said that my Yamaha outboard has seen over 1000 hrs of V6 fun, and its as strong as an ox. Mind you it does not get far AMSL.....well only a little bit at times
