What is the difference between a 99 engine and a 99S engine please.

When I open the site I look at the changes that have happened since last time I looked. These are usually changes in the recent messages column on the right of the home page. looking for chat and interesting things happening with other members.

Our next planned Yorkshire branch ride out is on Sunday 6th June, the destination is Matlock Bath, in my opinion its one of the best ride outs we arrange (unless the rain god intervenes!), so please do your best to get your Norton out an

Ahh! This time it works! Firstly, apologies for the previous abortive attempt to start a thread on this subject - computer problems meant that I could not get past the title...

Hi, I've bought an Amal Mk2 from RGM for my 77' Mk3, it was supplied witha 15pilot jet in the float bowl and a blanking screw in the carb body, is this right? do you leave the blanking screw in position?

Hi Gents and occasional Lass,

I was wondering whether the roadster tank, side panels and seat are a direct swap for those on my interstate ? like popping home to change for the evening !

Hi to one and all. I have a '76 850 ES which has been converted to belt drive and has most of the ES guts removed. I do have the starter motor which is the original 2-Brush type and one of the gears but no sprag clutch etc.

The battery on my 72 commando vented acid from the breather pipe.I didnt notice till too lateresulting in a nightmare of corrosion at the alloy rear wheel, chain guard, brake linkage etc.

I know very little about what constitutes 'concours' standards but assume it must have the bike looking like it did ex-works.

Whilst I am interested in standard Nortons (own a fairly standard 1946 Model 18) I'm sure that I can't be alone in having an interest in Norton specials. (as well as my model 18 I have a heavily modified Commando.

Anyone have an idea where I could find an air filter for my 650 Mercury? It is hot and dusty here in Cape Town and I would prefer to filter out the bits.

thanks

Can anyone tell me which concentric carb, jets, needle, slide etc would be required as a replacement for a monobloc 376/67 on a 1960 Dominator '99'. Robert Gittins.

Hi All, Can anyone tell me what is the correct or recommended6 volt battery to use in a 1961 Model 50 (Slimline frame)?

Many thanks, Alan

Hi everyone,

Probably two stupid questions someone might be good enough to answer, sorry for my ignorance.

Can I have 600 cc liners fitted to my worn out 500 cc barrels ?

Hi,

Hi,

Probably a stupid question but how do I get my Bellmouths off. I thought they just screwed on but they seem very very tight. Thanks in advance.

Cheers

Megaphone, Reverse cone, Siamese, Balance pipe, Expansion bulge and even the length of the inlet track are the results of design attempts to use the âKadenacy Effect.â in exhaust systems.

Currently the breather is just a short copper pipe on the rear of the drive side crankcase, Ithink it should be connected to the spareconnection on the top of the oil tank breather.

I'm re-commissioning a slimline. 1960 first registered in 1963. The headlight shell has a hole for the switch a hole for the ammeter and a hole in between the two. What goes in there?

Folks - does anyone have any ideas on this?

I have heard that there is clearance for WM2 or WM3 rim at the front and even for a WM4 at the rear, I am a little dubious.

Hello again

If you're thinking "Don't know much do you...", you would be right.

I will be travelling to Portsmouth for the ferry crossing on the 7th July, as I will be leaving from west Cornwall I will be driving up with the bike on a trailer, The parking rates for a car and trailer at the terminal are rather extortionate.

Hi I am thinking of replacing the clutch on my 1950 16H. It is just restored after lying for some 30 odd years.

Also I may change the carb to a new one, Has anyone any contacts for these items and what is the correct carb for my 16H

can anyone advise whether you fit heat insulating washers under the spring seats when fitting a 2s/combat camshaft in a 750 engine. regards alan

Anyone wanting just a tad more detail on Heavy Twin cylinder heads may like.http://atlanticgreen.com/nhth.htm.

My 1960 model 99 Dominator enginehas been totally rebuilt. It seems to have intermittent oil starvation to the rocker box.The oil seems to be going straight back to the tank instead of up the rocker box feed. Can anyone help please?

Has anyone out there got a Parts List for around 1961? Could you please let me know the part number for the bottom yoke for a 1961 Model 50. I guess it mightbe the same for all Slimline Featherbeds.
