There can't be many Pat Fribleys in Ohio who are interested in old British bikes, so I guess I have got the right person.
Remember me? We corresponded way back when I was an undergraduate at Oxford then somehow lost touch. Just thought I'd say hello having located you via the wonders of the internet search after your name for some reason came to mind and I wondered what happened to you in the 25 years that have elapsed since.
Briefly, I am now in the publishing and property businesses, was married in 95 and have two small daughters, live in an old manor house (500 yrs old) near Sheffield and have a taste for exotic sports cars. Yup, I'm afraid I never followed up the passion for bikes exemplified by elder brother, who has three including a superb Trident and a Benelli six. Ferraris are more my thing.
Hope life's treated you well in the quarter century since we were last in touch.

Do you have access to a copy of the Norton Owners Club Service Notes (UK) ?
One of the favourite causes for this is that the magnets on the early rotors were not welded to the centre and they can move outwards.
Once they contact the stator then it is only a matter of time.
