Having taken the conrods off I have found that the journals are of similar condition to the mains. A bit u/s. Crank looks pretty good though, no marks, very smooth. One problem I have is that I can't see all the crankshaft markings. The crankcase is marked BABBB. The conrods 2131. So the info I have is as diagram:

Assuming the missing marks are A and 1, am I right in assuming the main journals are Green, Yellow, Green, Green, Green and the big ends are Yellow, Red, Green, Red?
