Hi all, I have just become the proud owner of a 1953 ES2 Engine number 51410 H4 (it also has 00949 stamped down the front of the crankcase) I have had an issue with te clutch in that the nut that holds the centre of the clutch has come loose it di

Is there a trick way to fit the OHC side cover?  The caged rollers need to fit into the outer race in the cover - but the race has sharp edges on mine and it's a frustating, time wasting task.  I can't see any way to wrap thread round the rollers

I think my coil went pop earlier as it came lose and probably shorted out on the frame. Ordered a new battery too as its dead. 
Back to the coils, I use a Boyer  power box 12v system. So how do I know if the coils are non ballast? 

Just a quick shout out Noddy who lives near me in Poole and came after me seeing me push the bike past yours, after the old girl wouldn't start at the local. 

I have just returned from another bedding in run with my recently resurrected 650ss bitsa. I was making progress in top gear on a nice straight road when I noticed extra slack in the clutch cable.

I am about to fit the cylinder head to my Mk.3 with a copper head gasket supplied by Andover Norton. After annealing, they recommend a layer of Hylosil (Engineering grade RTV silicon) to both surfaces.

There's something weird going on with my Model 50. Sometimes a loud screaming sound appears. Bit like a slipping pulley belt, but not as high pitched. More like a rusty lorry brake or a really noise rim brake on an old bicycle.

Hi I seem to have end float on magneto drive engine sprocket is this right.

So, please will any purists read no further......On my 88 Cafe racer / track bike I have decided to fit a one-way valve to stop the never-ending flow of oil into the sump when the bike is stationary for even a short period.  I have fitted a Velo V

Hi, searching the forum for mag chain tension can't seem to find any info for a 16h.
thanks.
 

Short roadholders with internal springs being overhauled . Does everyone use 20wt fork oil and whats the capacity ? If measuring air gap do you remove springs and measure with forks compressed ?
Cheers. 

I see Paul Norman sells valve stem lash caps.  I'm replacing my valves and guides.  I wonder if caps are worthwhile?  Mine are both dented.  Exhaust more than inlet.  I've no idea of their origin.  New ones will be G&S.  If i am to use caps, v

Hi, Can anyone clarify the length that a Navigator fork spring should be ?
Part No for the Navigator is 23015 and an es2 is E2/620
Many thanks

Hi,
 A novice to all this Norton stuff . Can anyone tell me if the cambox pick attached is for a 350 or 500 engine please. Have a 350 engine with no cambox and found this in a box but have no idea if it is for a 350 engine.

1957 Model 50.  Trying to remove the pinion gear in the timing case. Is there a special tool to accomplish this task?

Ive just purchased a second hand Fastback seat and will recover it as part of my Commando rebuild project.

What`s the point / reason for the `Paper washers` that are fitted in Norton Roadholder forks ? I see them on all spares lists but have never come across any when I have stripped forks to service them .

Can someone confirm something that has confused me with the horn button switch?
I'm re-wiring my Mk.3 and have stripped & cleaned all the handlebar switchgear.

Hello Norton Enthusiasts

Hello....

I've decided to try 00 grease in my Dollshead. I know a number of riders use it or similar. My question, how much, In volume or weight do you use?

I've recently acquired an ES2 as a project to complete. 

I have struggled to find a diagram to help me re-assemble the primary drive - which had been assembled using washers as spacers - leaving the inner primary case on the piss.

Well I finally got to take the Navigator out for it's first run in about 50 years. Really enjoyed it.  Cert different.

Me again ! This is a simple question .. Should the Layshaft 3rd gear be 20T or 21T  on a standard Dommi AMC box ? Mine has a 21T whilst everything else i`ve read or seen says it should be 20T. ( The Main shaft it runs with is 21T )  ?

TVS Motor Company has confirmed the worldwide launch of four all-new models by the summer of 2026.

I stripped down my Dommi AMC gearbox as I couldn`t trust the person who apparently `rebuilt it ` and true to form immediately found a broken Kickstart return spring ! On continuing I noticed some worn `Dogs` on Main shaft 2nd and 3rd gear cogs.

Hi all,

Hi Guys, I intend to fit a pair of Premiers to my Mk.3 but not sure on jetting. 

Hello, I have 1967 N15CS gearbox number NA15221. I believe it has the correct inner cover with the kickstart spring looped round a steel boss but an incorrect outer, cast part number 06 0722.

Just acquired a model 50 but has no baffles in original silencer, so window-rattling loud.

Anyone got a diagram showing shape and size of the baffles?
