Britbike forum Forums British Motorcycle specific Brands Bsa bulletin board 1968-1970 A50/A65 Coil Mount Ref Photos

This is one way the A65 coils are mounted. If assembling from a box of parts, of note is the frequently missing special small spacers (thick washers) shown in the clamp closure. Those are key to prevent the clamps from closing too tight and crushing the Lucas coils. (note that in these photos, smaller 6V aftermarket coils are being used) And when those are NOT in the clamp, the clamp bolt will not prevent the coils from dropping down on to the engine case.

now i have to go look

See also my reply on the "British Bikes in General" forum: KC's set up is also quite different from a '66 or a '67 (the only two I'm intimately familiar with).

If I remember right, which I sometimes do, KC's mountings came in 1968, together with the Concentrics. The funny thing is, the brackets disappeared from the parts book that year, not to be listed until 1970.

It's all in the thread title.

Ooops!

Hah! Thank You Allan G! My original post was not titled with the years as this thread now shows. Good help!

Twas Gary,

But all the same, Thankyou for sharing it here. I will mark it as a sticky as mentioned.

From memory the 68-70 parts book still show the twin carb mountings the same as used to to 67. Despite these being the type
As used from 68-70 on all twin carb bikes.

It was I who changed the title for accuracy.

All I know is that's the first I've seen of that bracket, and it looks more substantial than the way I have them mounted. Would they interfere on a T-bolt? The alignment of the coils, carb and rocker feed caused many threads to be read a couple years ago. I never had to ask that question because EVERYBODY (edit: everybody building an a65 they didn't take apart) asks it. Still never seen that bracket before
Thanks!
So what is the part number?

I haven’t been on much with working away, just assumed KC thought it was myself who was highlighting the years, didn’t know it had been changed 😅 your just too stealthy Jon 😅

KC, your photos got a real belly laugh out of me. I only wish I had them about 5 years ago when I put my '68 Spitfire together, things would haave been much easier. I bought my Spitfire from the estate of a guy who died of cancer. He had occupied himself before the end by taking every nut and bolt and washer and spacer apart from every other one, and stashing them all in a series of random boxes and coffee cans, and doing the same with the parts that were thus undone--no rhyme nor reason to anything, just nuts, bolts, washers and parts in random boxes, and to make it worse he mixed in some A50 parts, and some stuff that I think came from a lawnmower, and some car parts. Everything randomly stashed in boxes. I am a cancer survivor myself, and so I understood what the guy was going through at the end, and I had a lot of compassion for him, so no hard feelings at all, although I found myself thinking how much easier it would have been if he had simply removed a part and put the corresponding bracket and bolt, nut, bolt and washer and spacer back through the hole it came out of and gave the nut a twist. But HA! nobody ever does that. The resulting random detached bits thus made for a big three dimensional jigsaw puzzle or logic test or something, and it was fun and a challenge to get every odd length bolt and every bracket and their corresponding parts into the right place, and by the end of the day I got it all right--and believe it or not I had everything but just a couple bolts --almost nothing missing. But since I am a Triumph guy, I didn't immediately recognize some BSA stuff. And the absolute most challenging and mysterious thing to figure out was--you guessed it--the 1968 coil mounts and their attending brackets and spacers. None of this stuff was well imaged in the parts manual, or in the BSA restoration books. I ended up sitting out in the garage for couple evenings, holding a bracket and some spacers and bolts I was left with, turning them this way and that way, trying to imagine how it all went together, with like a big phantom question mark floating over my head LOL. Man, if I'd only had your series of photos it would have been much easier and taken half an hour to get the right pieces in the right place right away. KC, you have done a real service to BSA-dom here!
