An oil leak from the back of the timing case where the dynamo fits in led to a partial strip of the timing side, to replace the bronze bush in the inner timing cover, which turned out to be the type used in the crankcase and consequently scrolled for oil control in the wrong direction, which led to oil accumulating in the dynamo drive portion of the timing case. The correct type of bush was fitted just before this test ride, which, so far suggests it might have cured the leak.
