I don't know the answer to your question and suspect most modelers won't either.
But - I do know that just like Saito many different sizes of YS engines use the same parts. For example the Saito 82a & 82b use 65 cranks and 100 pistons and cylinders which means many other parts are the same also. In fact they list some parts as working for many engine sizes.
