IF YOU STILL HAVE YOUR OEM CHAIN OILER...

You could replace the "Dust covers" and O-rings...

...with the "sealed pivot" seals?
That does look like a much better solution
 
Definitely using 140w, but I guess the o-rings could have gone off, I last replaced them in 1981, but in my head I know I replaced them so they must still be new :rolleyes:
That's why you need a maintenance journal . Log in the maintenance and the dates of . Helps the memory to refresh .

I do record everything, and keep the receipts, thats why I know I changed the O rings in 1981. I could even tell you what I paid for them , but it a very large pile of receipts and I'm sure nobody is interested.

Its more a state of mind that says that everything on the bike that I haven't examined is suspect, everything I've replaced is now OK. But unfortunately some things have been replaced and now need replacing again, I need to adapt to recognise that.

Yes Mike , I also have a bag full of receipts myself ,totaling well over $40,000 over owning 4 Nortons over 50 years . For the first 35 years I kept no maintenance logs on the first 3 . Now I realize the importance of doing so over the past 15 .
