I was working on a starter problem in a 82 Harley fat boy, I found it had the wrong Jack shaft in the side cover. I told my buddy to contact his mechanic to find out if the part had been swapped. Well It was replaced, ( by the mechanic) Who then stated That he did not work on boats, and what was I doing working on a Harley. " the shaft Is NOT the problem" . Well 6-7 more trips to the dealer, And low and behold "THEY" found the jack shaft was the wrong part. Guess they forgot the prior conversation. I'm not sure if they told my boy about all the "mud"... I guess the point is give 'em enough rope...
