I put a mikuni on a 1960 shooting star engine, it was advertised as jetted for the bike, I did some plug chops and am very happy with it apart from cold starting , probably my fault [its always my fault *whistle* ] putting the choke on and giving it some throttle as well-- old habits after tickling the amal ;)

A 26 mm concentric might be worth considering. Easy to get, easy to tune, plenty of parts. Also you'd be supporting a company who's taken the time & effort to cater for our 'obsolete' machines.
( I'm in no way connected to the company)

Frankly I'd fit a monobloc - may not be 'modern' but they can be bought new and are thoroughly reliable. Used on many models of BSA

I used an Amal Premier on my 51 A7 mainly because space was tight between the head and the down-tube.
Well pleased with it.
