Dispite the previous conflict,

I am back on topic with a tidbit...
1. " Made In England" sprocket easily cut with a hand file.
2. Side note FWIW: My spare sprocket, made by AFAM for one of those 3rd world bikes (Ducati), tested with my Ames hardness tester, showed 62RC just like the OEM Norton Motorcycle (factory) sprocket.

Dynodave,
Yes back on track.
It looks like johntioc / John Healy is just a one time poster and I am still waiting for his response to the discrepancy between the measurements with old stock OEM and current production.
Cheers,

Dave where did you source the AFAM sprockets?

Got the EMGO-Taiwan 21T norton sprocket in todays mail.
I just finished two tests and got 54RC and 56RC. So these seem to be more similar to OEM Norton factory...not meaning current andover norton.

AFAM/Ducati sprocket was bought soo long ago, maybe 10 years, so I don't remember... sorry
