Yamaha has just released a new jubilee model in paper, the model has the scale 1: 4.
This is far too big for me, so I'm going to reduce the model to 1: 9 and then much more realistic.
Note that the whole model is made out of paper.
The cylinder in rough form to see clearly that the paper is.
Here you can also see that the spark plug is not beautiful.
Spark plug made more realistic.
Cylinder and head painted
Carburetor made, hoses and cable are made from sewing thread.
