This has been a giant faff!! Much more than was anticipated… The Grey Flash exhaust pipe is just a 2″ straight-through racing pipe, right? Well, there were several types employed and there is very little data out there. The period shots we had of 2751 were as good as any a place to start. Bert …
Whilst we are waiting for the exhaust pipe to be made I thought I’d post a bit about the seat we will be using. Early Vincent HRD racers came fitted with a trimmed version of the standard road-going seat. I believe these were a Feridax product that featured a Dunlopillo foam with “cells” cast into …
Amongst several of the period shots that I have of 2751 racing in-period is one set of 4 images. The photos have been marked differently but were obviously taken at the same event. Recently I was looking closely at them and noticed a road sign was visible. One of the captions mentioned the Matarawa GP. …
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 …
