New BSA owner with a couple questions

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

Likely the side stand lug is broken off, a consequence of kick starting on the side stand.

The disc is the speedo gears installed in the trans.

If you are looking at the frame below the forward part of the left engine case, there should be some evidence is was there at one point. If not: count yourself still lucky that when it broke off, it didn't tear out a chunk of the frame tube as many have done! That gets to be a real challenge to repair. See? Still good news! How about posting the engine and frame numbers here? We always like to figure out what the bike is,... Or at least started out as. 3,000mi seems awfully low, but possible I guess. More likely the speedo was replaced. How is the overall condition of the bike? If you can post a photo or two that would be good. Have you had other Brit bikes? Good luck, and welcome to the Board!

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 ....

Is everybody absolutely sure that these were originally fitted with a side stand?
I raise this point because the very early A50s/A65s had a lot of features carried over from the A7s/A10s and to the best of my knowledge the A7s/A10s were fitted as standard with a center stand but no side stand.

Every A10 I've seen has the sidestand "half lug", which has threaded holes to mate up with a matching lug on the sidestand. I just bought a sidestand to mate up with the one on my 61 A10.

But maybe I'm just lucky there.

The engine number is A65D1385 frame is A50B2416

The story I got from the last owner was that it was in a minor accident shortly after it was sold new. The headlight front fender and maybe even the triple tree were replaced quickly to get it on the road again. The headlight shell is not correct as it has only the speedo in it. But it seems nobody finished putting it back together. A friend of mine bought it in the 70's and the title said 2700 mi then and he started it, rode it a little, then started to correct the problems. He lost interest early on and its been in his garage since. Ive known about it for many years, and he finally sold it to me with most of the parts to get it right.

I'll try to get some photos posted.

yo, garbin.

welcome to the forum.

you've got a bsa, which is good, because there are no crazier fanatics than bsa fanatics.

put up pictures, and they will volunteer hours of analysis to help you figure your bike out.

when things slow down, put up another picture. they can't help themselves.


every day you do not take a chance is a day of your life that you will never get back.

S/N makes it a Lightning Rocket. Dual carb, droop top yokes, dual clocks mounted on the yoke. A headlight bucket with a speedo is a Thunderbolt Rocket (among others) and is somewhat rare. As is the correct bucket with no clock in it.

Front fender is a std 6 tab.

Post some pics, LR's were built with a surprising amount of variation for a 2 year model. I would be interested in seeing how this one is trimmed if it is reasonably intact.

There ya go kevin.......I already confirmed your analysis of BSA owners...... laugh
