feedback from Kevin is

I love it! Quite a bit of learning along the way. I should have just used the 21-21 engine sprocket. The hardest part is the primary chaincase.

Looks like I need to get some alloy casings as that appears to be a better route for maintaining an oil seal for the primary.

Does the alloy chaincase have the same engine to clutch centres as the pressed steel chaincase?

Does the alloy chaincase have the same engine to clutch centres as the pressed steel chaincase?

I don't have access to check but (if the engine and clutch sprockets are the same size on each model) would comparing the number of primary chain links for each provide a clue?

Speaking from my point of view of ignorance , surely the cast aluminium case parts will be thicker than the original pressed steel case, so there must be other changes ...

the alloy cover does not locate the starter / gen unit . its bolted to the engine plates , so a tin cover could still be used with suitable shielding of chain

Reviewing the pictures it looks like a BSA chain case has been modified in this instance.
