Clutch run out

The clutch on my 1963 G12CSR has visible 'wobble'. The primary chain is tight on one side of the sprocket and loose on the other. The transmission mainshaft runs perfectly true. The "clutch back plate bonded" is true withing .004". Can anyone tell me what the most likely cause is? Thanks

With the cush drive rubber insert system it will be hard to get it to spin true.You could try a set of new rubbers.I never really liked the system.A cush drive in the rear wheel is much better. You could keep trying different positions on the mainshaft spline for a comprimise.
