Silly question, but does it say vortex on it?
Reason I ask is that it looks a lot like a Rotax VM-C, especially given it has an older motoplat coil on it. Those can be swapped of course, but the 95 vortex models came with the PVL ignition.
Not really, there’s a lot of interchangeability. Essentially they all run the same bearings, pistons and rods. Rotary discs can get a bit tricky with the rotaries, but otherwise parts are not to hard to come by. Worst case scenario you’ll have someone in Europe bag something up and send it overseas for you.
Look on ebay, Facebook market place. I very often get notifications on Facebook for something basically selling everything their ex-husband or recently passed father or some other relative left in the garage and they often have pre2000 chassis and engines in the mix.
I might be lucky and there was a big following in those classes where the live now but Id guess it’s true of any largish metro area
