In this post I will give instructions on how to mate with a 1940s Smiths chronometric tachometer… 🧑🏻🏫 Okay, that was a lame joke BUT such is the patinated beauty of this instrument that just looking at it positively generates an erection… The bracket was re-profiled as outlined in a previous post. It was then …
A correct pattern tacho drive gearbox was sourced and fitted replacing the incorrect unit fitted to the bike as acquired. Sorting out the tachometer wasn’t quite so easy though… 2751, being an early bike, wasn’t ever fitted with the rare racing “yellow number” tachos. Using what came with the bike + another head, Bert assembled …
Herewith two shots of the current state of the restoration. Not long now until completion…
Sourcing the correct herringbone patterned oil/fuel pipe has not been easy… There are still some stocks of 3/8″ ID pipe available but stocks of 5/16″ ID pipe have dried up and none is currently being manufactured. The correct run of the oil feed pipe was determined to be as above. We decided to stick with …
The title is self-explanatory so I’ll just annotate the photos. Running the throttle cable over the brake lever like that looks weird. In-period some were set up like this though and it’s actually the best route for the cable. We might revert to running it behind the lever later on – it can be changed …
All Vincent racers were supplied with Axle bolts rather than the T-bar arrangement seen on the roadgoing models. This is quite an obscure component and falls into the “not a lot of people know that” category… This rare racing part is depicted in the Spare Parts List. 2751 was missing these important parts and they …
Throughout its long racing career 2751 suffered many incidents that left their mark on the surviving original components. The magnesium gearbox casing bears “witness” marks from where primary chain slackness had been adjusted to the point where the casing was pushed up against the G50/2 pivot bearing plate. Once a new primary chain had been …
Herewith some annotated shots showing the current state of progress of the restoration. Despite the usual annoying setbacks, things are progressing well.
Bert Carefully replicated the the tacho bracket from the E.M.G. Stevens/F. Griffin drawing held on file by the VOC. The Club has taken great pains to create a database of accurate drawings for every part employed in all Vincent HRD motorcycles and “The Drawings Project” is still, as far as I’m aware, an ongoing process. …
Bert and I have been studying period photos of 2751 in order to ascertain how to route the cables and their lovely fabric sheaths. In all the period photos the brake beam balance stop is on the “wrong” side and we have installed it this way round. The upper fork link bears a “witness mark” …
