Well here is the story. The action took place in Sweden. On the photo two men one of them is the owner (right) of the old Soviet Union motorcycle k- 750 build in 1954( if you look closely you will see litle stars on the rear fenders). Another (from left) expert of the renovation of those kind of things and he helped adjust the engine and the gesture shows that he did everything in his power, and better than now this engine will not work...
