JIM's 1942 BSA WM20 - Mission Impossible?
Starting to look like a bike
January 2007
With the new guards fitted, the engine in the frame and the wheels and girders on she is really starting to look like a bike at last.

The primary side, as always, presents its challenges. Despite having one of BSAs strongest clutches, the M20 clutch - like all BSAs - must be carefully adjusted in order to get the best performance. Jim has been collecting parts to build up a full clutch assembly.

A closer view of the primary side. Note the new battery carrier. The most amazing thing about this restoration has been to discover the wide variety of reproduction parts for the M20 - mostly of very reasonable quality. There also appear to be an equally good supply of NOS parts still available.

More progress. The carby has been re-sleeved and had a full renovation. An exchange magneto and dynamo has been fitted with fully rewound armatures. The new headlight is in place togther with the handlebars.

Jim is reaching that annoying "last stretch" of every restoration where weeks are spent on the detail additions. Here he is pictured fitting the rear numberplate bracket and light. Both are reproduction items. Also note the rear stand. This repro item - previously very hard to obtain - is now available. The return springs can be very tricky - and dangerous - to fit. For information on how to build a spring tool see Hans Muller's interesting WM20 site.
Next jobs - electrical wiring and primary case. |
