The bike needs to look like a BSA but the colour should not matter, just make sure that the frame number can be read, powder coating, being thick, often obscures part of it.

Parts may need to be refurbished, a wheel might need to be refurbished by fitting a new rim for example. Forks may need to be refurbished due to worn shafts and bushes. I think most bikes going for an age related plate have be refurbished to some extent.

The major parts are the frame, engine/gearbox, forks, wheels and brakes.

I agree with Bess - it is excellent also easy to apply and easy to remove.

Beware grinding paste sticking in the soft zinc alloy.

With the drive being off centre then it will be forcing the toothed wheel into the side of the oil chambers  causing uneven wear.

You can grind away the high spots but you cannot fill in the low spots.

Do you know what caused the original blowup?

The stiffness is often experienced with oil pumps, especially the ones made from nasty zinc alloy. Bodies distort and chambers get mishapen and can pick up due to the clamping when assembled onto the crankcase and the material used.

The oil pump is the heart of the engine and has got to be spot on. If you dont want to get the SRM item, which is a first class product, then at least go for the later cast iron one which are much less prone to distortion. They are not cheap either.

If the frame number is not in the despatch books then there could be a problem registering it as an old bike. You could end up with a Q and you might need a type approval.

See DVLA website.

However - sometimes owners do not give clubs quite the correct number - misread it (2 for Z, S for 5, Z for 7 and a number of other possibles) or part obscured by paint (especially powder coating). It is worth viewing it and forming an opinion on the number and compare it with the letter and getting an account from current owner. If the number is really odd then I suggest beware.

Do you know what it is? Does it look like it is a proper BSA number?

I use PTFE tape and exhaust paste on my A10. Seals well and comes off OK. Have also used PTFE tape and high temperature Loctite 5920 (copper) also works OK.

I will send you a PM look under "My messages"

That is for an A10. Part 67 4847.

You can see the tongue on the cross piece of the A10 stand which takes the rectangular end of the spring they sold you.

You need 65 4727.

Below from 1951/52 parts book.

Singles / Re: B25 POINTS IGNITION
« on: 21 October, 2017, 11:41:03 »
From parts lists it looks like they were both originally fitted with the same Lucas 4CA complete assembly part 47621 (condenser mounted on points plate). The B25 changed to the later improved 6CA assembly (remote condenser) but dont know about the Triumph.

The auto advance/cam unit has a different part number for 4CA and 6CA so presume you cannot mix parts from the 2 assemblies.
