I have 2 bikes, had one since around 1972 other since around 75, both have been sitting in my garage ever since, I am now at retirement age and would like to take the 2 and make one good bike, I have no idea what year either one is, one has a number on the block of 48-1225, the cylinder head has M1126, the other block only has the number 205 on it, the cylinder head also has 1126 on it, I will try to post some pictures, one bike is together, the other I have removed most of the parts and cleaned them.
