As has been said here before those trade skills are often lacking, and most of us are probaly jacks (or jills) of all trades with the well known consequence....

No shame in not knowing much about Meriden twins. Now if I didn't know about Norton singles I'd hang my head......

I still think they serve no useful purpose (the finned rings not Triumph twins). Althoug come to think about it.....

I'd suggest joining the Velo group formerly on Yahoo but now at https://velocette.groups.io/g/main. There has been very exhaustive discusion of this very point n
and there are some real experts there.

Yes, can see them via the link.

That's a very well thought out and complete response from Leon. If you follow it you're much more likely to succeed.

I nver liked the plastic needles and always change them to viton tipped brass ones.

The lack of registration / documents may well be a problem. As to value - no idea, but ebay is probably where you will get as much as anyone want to pay. TBH I wouldn't imagine it's worth a lot. But then I've been wrong before.

There's a lot of debate about doing this for Nortons which have a slightly better oilbath chaincase. Some people who've tried it report reduced chain life, and of course the oil lubricates other things like the clutch bearing.

I had an odd hybrid for a while - Norton ES2 engine / box in an Enfield frame - and because of the close coupling of the engine and box only an outer cover over the primary chain. Despite frequent oil can applications the chain wore very quickly.

I think one problem is that Velocette were always on the margin of viability and like Norton spent a huge amount on the racing machines. Although this meant that much good stuff did percolate down to the bread and butter bikes it also had the result of limiting investment. The Velo clutch, for example is just a refined / bodged (take your pick) of the original which was fitted to a lowly 2 stroke.

The persistence in running the final drive outside the primary, although having some racing advantage in giving a narrow stiff crankcase and ease in changing final drive ratios, was not that useful to the road rider and indeed given the number of people unable to read and understand the manual led to incessant problems with clutch adjustment. You only have to join the Velo "forum" to see a lot of new owners struggling..... https://velocette.groups.io/g/main/topics
