 Hi all,
 Dont the 13B's have wider rotor bearings, thus making the 13B Eccentric
 shaft unusable with a 12 A rotor?

 Case

   All bearings are the same in the 12a and 13b at least in the later 12a's.
  While on the subject I am working on a single rotor cog belt redrive
and will send photos when it is done.
