I have surfing the internet checking out photos of B44's psyching myself up for another rebuild. It seems there are a lot of bikes with a single speedo and a few with speedo and tach. Did these come from the factory either way or is the pictured tach something added later on?
My bike ('69 B44 VS) wears a 150mph speedo, seems quite optimistic. Would it have originally come with the 120 mph instead?

All B44s have a speedometer only and it should be a 120mph speedometer. Not only is your 150 the wrong one it will also be inaccurate unless the drive gear has also been changed to a 15/12 ratio unit. The stock drive gear unit compatible with a 120 speedometer is a 2:1 one. Changing the speedometer without due consideration of the drive gear ratio and turns per mile specification of the speedometer seems to be a common mistake. For a B44 which has a top speed of 90mph even a 120 speedometer is optimistic. Your 69 should have a black face speedometer compared to the grey face model of earlier years,
The tacho was an option and you need the parts outlined in the parts books, rare as hens teeth and there are more of the B50 versions around which was different to clear the OIF frame but will retro fit to a B44 with ease.
I had a 1968 BSA Starfire which i had tuned by Gander and Gray,Romford, England. It had a speedometer and tacho from a BSA Spitfire 650 , and the drive came from the contact breaker housing, obviously modified. Goldie John.
B44VS (Victor Special) came with a speedometer only.
I think the "Victor roadster," the street version with the bigger tank and low exhaust, had both speedo and tach.
As std both VS and SS came with speedo only, in 69 a hole was added to the crankcase which allowed the fitment as an option for a tacho from that year onwards, this applied equally to the B25 and all variations of B44 for 69 and 70. Not sure if the option was factory fitted or supplied to the dealers as kits, there are OIF B50/B25 kits around so I suspect kits rather than factory fitted but no variation had the Tacho fitted as std. Oddly for 70 the VS came with a 150 speedo and 15/12 speedo gearbox and the SS stayed as 120 mph and 2:1 gearbox as detailed in the parts books, odd for an off road orientated bike to have the higher speed speedo.
Eight years ago, when I had completed my 1970 Victor restoration, I found a guy on EBay selling a half-dozen or so NOS BSA B44 tachs. I got it in the original packing, complete with mounting bracket and cable. It was in absolutely new condition but dry as a bone. Once lubricated, its been on my Victor working perfectly. I recall it being a bit dear, a few hundred bucks, but it looks and works great.

As I recall, the tach for the Victor is different from other BSA tachs, has a different ratio than the twins'. 3:1 vs 4:1? The Victor tach is a Triumph ratio, not BSA. Worth knowing if you are acquiring an assembly piece by piece, which also can be done off ebay... with mucho patience.
