Heavy Twins

I am rebuilding the cylinder head of my 1959 ex Paul Smart 600cc Dommie but I am not sure what the valve springs should be although I have checked the main dealer websites (Andover/RGM/Norvil).

Hi everyone , need some assurance that the Haynes manual is correct ? Does the oil pump only have ordinary reduced head nuts holding it down ?

Afternoon all.  I have spent the last 6 weeks inventorying my parts, cleaning the cylinder head and removing rust for my 54 Dominator 88.  I believe I am ready to start rebuilding the cylinder head.  Are there complete kits out there that include

First I would like to wish everyone Health and Happiness for 2025 and secondly I would like to ask the people with far more Norton knowledge than me a question.

Hi can anyone give me a bit of advise?
I am doing a refurbish project on a 1955 Norton Dominator 88 twin Deluxe 500cc
This bike was  last on the road in 1967, it was taken apart and never done anything with.

The badge in crankcase on my '53 Dommie loose all painting and time to swap with new one.
How is the best way to remove the old one to avoid any damage?

Greetings from the Shed

I am searching for a mythical creature, something of an unexpected rarity round these parts. Something I would not have thought to be an issue..... but what do I know! 

Hi does anyone know the size of this bolt just to save me taking it apart?
Is there a retaining nut inside or is the headlight casing captive?
Thx
