Here are some news, from here the engine looks good, no rust or damaged part, some wear.

The piston have a little defect on the top surface, do you think it's an impact from a part or foundry default. it seems that the valve has no issue.

Concerning the gearbox, the kick sprocket has a damaged teeth, the overall looks fine.

About the bearings , do they have the reputation to be leak ?

Do you change them automatically ?
