|This motor powered its rider to an AFM
500 GP championship; but not recently! Three of them were once owned by Albert
Gunter. They all had the same engine i.d. number! It corresponded to a production
engine type of the time, which was similar in appearance. The AMA rules for racing
under what was known as "Class C " then in effect required the same engine to be
used in heats and mains which you qualified with; if you scattered one it was a
disaster. Class C was also a set of rules based on production motorcycles, or at
least their engines. It would seem that someone had the idea that these
motors, which were once used in GP racing on the Continent and quite a bit in various
English clubman events, might be a "secret weapon". They were so
slow probably no-one over here cared. But they sure were good-lookin.
|The magneto timing gear, furthest left
in the photo, has a vernier timing adjustment.
Any of you that ever set the Magneto timing on a
pre-unit Triumph or Notrun Atlast would have liked one!
