Placing a washer in the cradle for the dynamo cannot be a good solution, I have no idea what would be, but that aint it.Managed to sort out the dynamo problem. For some reason the dynamo was sitting at a slight angle to the face of the rear primary case. It had about 50 thou clearance at the top whilst hard up at the bottom. There is no logic to the following. Placing a washer from 1/4 bsf bolt under the primary side of the dynamo collar lifted the face of the dynamo so that it mated fully with the rear of the inner primary case. I then clamped it into position and the sprocket, with a shim, sits with acceptable clearance in the middle of the primary chain centre links. Whilst writing this I have seen the light - lifting the rear of the dynamo changes the angle of the sprocket by pushing the top out and the bottom, therefore, draws in. The nut is on far enough too. All's well that ends w .... lots still to do!! Exhaust system looks fabulous!!

Thankyou for a well-mannered and constructive comment. The dynamo cradle on the B is cast into the crankcase so shimming underneath the cradle is not possible. To others I'd like to say that I was pointing out that a solution in terms of dynamo orientation and angling had been found and that my next step would be to create a shim to do the job in a neater fashion.
