Thanks Oddjob, I'll let you know. With the new shells I've got I'm going to go along the crank and plastigauge each journal to see exactly what clearance I've got and make a decision from there. At least I'll know how compromised I'll be using green shells. If the clearance is too great I'll have to think again.

Thanks for the info gents. I have the casing codes as they are clearly visible and was lucky enough the be able to see the original crankshaft codes on the crank for all the journals. Although the bikes a wreck the engine internals aren't that bad. There's very little wear on the crank.

I've tried all combinations of the part number, no luck yet.
I'll let you know how I get on.

Hi All.
I'm new to the site so forgive me if lots have already asked the same thing. I'm rebuilding a basket case 1975 cb400 and have come up short for some crankshaft main bearing shells. I'm after 4 x 1331 8333 003 yellow shells. Any ideas or has anyone got any spare new ones they would like to sell?
Thanks.
