Toolbabe once found a three yoke egg from one of her yard birds. It was delicious.

Hoosier, the BSA I just picked up has mismatched yokes. My bottom yokes ID is too big for my tubes. I'm new the these so I dont know what it is supposed to fit,but if you give me some clues I'll can see if it's what you need.
Saw your hardtail Shiny... friggin SCORE!

The A65's had a couple different verions of yokes (triple trees)

The earlier models were dropped out at the tubes and the handlebar mount was towards the center.



PRoblem with these is because they were dropped the fork tubes and headlight ears were shorter then mine.
 
Then in 66-67 they changed to have risers cast in and pulled back to the rider like mine. These would have been fine for the stock tank, but hit on my early Goldstar shape Euro version.

Both of these use a fork tube that have a taper at the top, no pinch bolt in the upper yoke at the tubes. And the pivot hole was larger for the damper adjustment knob and sleeve.
 Then in the '70s when they went to the OIF models, they went risers that bolted on but the tubes were straight, no taper and the pivot hole was smaller for just a nut, no damper adjustment. That is apparently what I bought off Ebay that was incorrectly listed as a '67 BSA A-10's yoke.




I have read the A-7 or A-10's of a similar year used the same tubes and what I have been searching for... but I am starting to think I need to just pick up another original and cut the risers off ... or get one machined out of a hunk of billit aluminum.

Hmm...my lower looks just like the one in your top pic. But my tubes are too skinny to fit it. I gotta do some BSA research. I'm totally ignorant so far...which is typical.
