Chris, Very accurate and well done! The M151 refers to the model number of the motorcycle, usually a better way to identify all Bultaco's rather than the year of production.

The hi boy frame got rid of the under engine frame tubes. I used a Miller hi boy frame and a Suzuki TS 250 engine in a 182lbs wet machine. Also took a trials school from Sam.
