C11 Frame/VIN location
« on: February 14, 2019, 03:00:41 pm »
Hi all,  Im. from Perth Australia. I've recently joined, after being given my Grandfathers inlaws 49 C11. I've managed to get the Engine Number, and a second number from the front of the Engine. I cant imagibe this to be a frame number as Id imagine that would be on the frame. So 2 questions,;
1/ where do I find the frame number?
2/ what is this number in the attached photo?

The frame number is stamped on the left hand side of the head stock near the front left hand fuel tank mounting, Mr E. Sometimes it's difficult to read if it's had a thick coat of paint over it.

The top number stamped on the alloy case is the BSA part number for the finished crank cases and the 140 numbers show that the two halves are a matched pair. These numbers were stamped on after machining and before the engine was assembled.

They're belly numbers, and show that the two halves are still a mating pair as from the factory. Good to see!
