Unfortunately, Nagy doesn't have any photos or information either; he told me the engine was made many years ago. Is there any way to contact this Kiel guy?

Unfortunately, no one answers. Are these users more active on the forum?

Thank you very much, I wrote to them, I hope they answer

Unfortunately not, the spare parts catalogue only lists the codes of the gears required for the gearbox, but it doesn't say anything about how many teeth they have. A photograph of the gearbox of an S-branded engine would be needed.

Good morning, I'm trying to understand the gear ratios Piaggio intended for sidecar engines, such as the VSM1M or later. Does anyone own engines like this, or do you have this information? Photos of the inside of the engine would be sufficient so I can count the gear teeth.
