Nortons - General

Can anyone tell me the dimensions of the rubber sealing strap which goes around the inner chaincase, and whether the rubber is relatively hard or soft?

My buddy saw this pic on facebook, and thought I’d like it.

The speedo in my 57 Dominator 99 (mph) is marked  1550,   S467/203N.

Is it the correct one?

I haven't checked it against another vehicle yet, but I have the feeling it is reading too fast.

Can anyone tell me the exact sizes for the two oil seals, gearbox drive side outer and engine crank shaft drive side? For my 57 Dominator.

Hello, new member and first post so hopefully right forum.

A Dominator I am rebuilding came with rear shocks shown in the picture. At 70mm diameter they are too wide and foul the mudguard.

Dimensions are 11" x 2-3/4" shroud diameter.

Does anyone know what they come from?

Hi does anyone know anybody in North Wales who could spray and reline a petrol tank?

Over the years I have seen a few Nortons with a hydraulic  front brake conversion, utilising parts from some car or van, does anybody know what the donor vehicle was?, I know there are probably dozens that would do, but scrapyards don't let you wa

Does not seem to work?

I know that the cable ends for magnetic clocks are different to those for chronos , but whats the difference ?.
