Hello asaff and welcome!

If you let us know what the engine and frame numbers are I can look the exact type and year up for you.

Cheers, Markus

Hi. The easiest way to tell is that a 500cc  A7 has 7 fins on the cylinder barrel (below the head gasket face) and an 650cc A10 has 8! The numbers on the crankcase can be misleading!  I once bought an A7 bottom end only to find out that it was an A10 built into A7 crankcases. Regards, Peter

Asaff,

Welcome. That looks like a very good project. Is it currently in running condition? If so, we assume you are enjoying the riding. I think of it as riding a time machine.
