Just checked that number in the despatch record. Not recorded as being fitted to a 36MX4. There is a gap between 221 and 224. Possible that the engine escaped from the factory, or just sent out as a replacement. Maybe, fitted to a speedway, or grass track bike?

Or more likely fitted to exported bike, I have lots on survivors records in USA.the 36MX4 was a popular bike there.

I would say the bikes in the gaps in dispatch records was exported
