What does the "G" stand for?
« on: November 26, 2008, 05:56:24 pm »
Hello Everyone.
Not a technical question, but a trivia one... Does anyone know what the "G" stands for in C11G, or the "L" in C10L???????
And what changes to the C11 prompted the addition of the "G"?

I  think that G stands for Generator, when BSA adopted an alternator instead of a dynamo and L for Lightweight because a lighter frame derived from the Bantam was adopted for the C10.

Roy Bacon's book "Illustrated BSA buyers guide" says on page 49, after talking about the C10 & C11,
"Both were replaced for 1954 by models with an alternator on the left end of the crankshaft, and the points cam and its auto advance on the end of the camshaft.  In this form the side-valve model became the C10L and the ohv the C11G but, except for the electrics, the engines were essentially as before but with a new timed breather"

Didn't the rocker box lose it's breathers when the "G" was released?
Obviously the whole crankcase shape changed with the loss of the dynamo and associated drive train and cover. A metal cover was introduced to hide the gap created.
There were naturally the cosmetic changes as well - seat, tank, headlight etc. - not really related though.
Carb changed as well at some point.
In fact the C11G was quite different to the old C11.
