I have thoroughly enjoyed this thread from the initial find and start up to the exponentially expanding discovery process and subsequent tear down. I have a question about the three cylinders that has bugged me for a long time. I have built many old piston port two-strokes for mostly Ossa and Penton engines. All of them have been singles and the pressed together cranks seem like child's play next to a pressed together three cylinder crank. How do you disassemble, reassemble an true such a complex crank? Is this a job for a specialist? I have shied away from three cylinder, two strokes, as project bikes, because I figured that the crank seals would need to be replaced.
