About a month ago I acquired a 64 BSA Lightning. It's in fairly good shape with supposedly only 3000 original miles. There are a couple things that puzzle me about it. One is the fact it has no side stand and no provision for mounting one anyplace on the frame. This seems odd to me, is it odd to any of you? Two what is the significance of the little round tag screwed to the top of the case above where the kick start is with the numbers 7 and 10 stamped in it?
Thanks in advance, Gary
There was a side-stand lug there once.
It was "furnace-brazed" onto the frame at the same time that all the OTHER frame lugs and tube joins were made. All the frame tubes and lugs were jigged up together on an alignment jig, braze metal and flux was applied to the joints, and the whole assembly was put in a furnace to braze it all together.
Problem is, when the sidestand lug braze breaks loose, there's no good way to braze it back effectively. And it can't be welded, because the joint is contaminated with brass.
That happened on my '69 A65. The sidestand lug was just rotating on the frame tube. They break even if you don't kickstart it on the sidestand (which I never did).
After taking much advice, my solution is:
1) Take the engine out of the frame (there's no room to work otherwise).
2) Use a Dremel tool with a cutoff wheel to cut the cast sidestand lug off of the frame. Two careful cuts and it falls off (yours is already gone).
3) Folks sell weld-repair sidestand lugs for BSA and Triumph on eBay
and other places - you can Google them. They need a bit of handwork to fit but when the frame is cleaned of all of the traces of brazing, they can be welded to the frame tube.
I'm in the middle of the process. I'll take pictures once it's back together ....
