I would like to canvass for some opinions. We are still struggling to find a suitable location for the 2026 national rally. We were hoping to have 2026 as an 'undercover' rally as 2025 was a camping rally.

Thanks in advance to you all. I have three questions about mk2a.

Hi All,

I'm planning on fitting a one way valve from the timing case breather pipe to the oil tank inlet up at the cap. I have a Mk.3, but I'm changing the black box to a slim ham can.

Story in this week's MCN that production of the legacy Nortons has now ended at Solihull. 

Hello new to this forum looking for a bit off information regarding clutch basket hitting back off casing when tightened up is there a spacer between basket and oil seal on shaft 

Got my MKIII couple of months ago and was very surprised at the effectiveness of the Isolastics in that from 2,500 rpm onwards it is strong, smooth & vibration free all the way past 6,000 but below 2,500 and on the move below 30mph in 2nd the

I am often surprised at the queries raised on the forum which are easily answered by checking out the library documents freely available to members.

I am in need of a new float arm for my VM30 Mikuni carb but neither Allen's Performance or Motocarb are answering either emails or phones - except to tell you by recorded message to email them!

Investigating the reason for my speedometer needle twitch and intermittent drop to 0mph, I found the rear hub cracked at the speedometer drive collar left hand threads, the drive collar spinning in the damaged thread during drive causing the issue

When replacing the cylinder head it is fiddly to get & keep all rocker ball-ends in the pushrod sockets.

So today I lost the bakelite knob. It's not the first time. 
Has anyone been enterprising and changed it for a decent key switch off, on, on with pilot, on with main. Any that can be recommended? 

Hi,
if anyone's got a 500 twin crank in bits would you be able to measure the oilways inside the crank? should be either 1", 7/8" or 5/8". It would be good to know if it's a dynamo crank, alternator crank,SS crank....

Dear All
I have looked through the website to find the engine number list that I am sure I have seen but can't find it now!
So, If I am asking in the wrong place, I do apologise.

I'm at the early stages of planning a restoration of a 1928 ES2. 

Hi all,

Hi all,

Just wondering if anyone has a link for downloading a workshop manual for a commando 961? 
I'm sure I have seen one on the forum somewhere but not found it again since, if one exists at all? Thanks  Roger

Hi - is there anyone in Hampshire, Dorset or Sussex who would kindly lend me this tool (ET2003, NOC part number 067524).  I'm desperate!   Thanks

Is there anyone out there who would be happy to talk to me on the phone re. RGM primary belt tension/alignment.
Thanks   Roger (Mk2A)

Hello everyone,

I'm new to the forum, I've recently acquired my father's Norton Commando 750 Fastback, This bike has been in the family years, and my goal is to bring it back to life and do it justice.

I've been trying to fit the brake lever supplied with my ES2 without success. I bought the machine in boxes and have been trying to assemble it.

well looks like some good news from the DVLA makes a change ha. 

we shell see ?

Hi,
there seems to be an error in the dominator service notes that state that only early dynamo cranks had 1" oilways. I just opened up an alternator 88 crank and it too had 1" oilways.

Looking for spark plug HT leads for a Classic. The manual states they should be 600 ohms . I cannot find anything close to that. Will  5K ohms caps work? AN does not have any in stock, and the ones they list do not have any specs. 

Good morning all.   As we we all know our lightweights used the same frame as late Francis Barnett bikes.

Can anyone recommend a good petrol tap for my slimline ES2. There is very little room between the tap and frame top tube and frustrated fitting taps that leak.

Many thanks 

The clutch operation on my newly acquired bike is truly horrible so I dismantled the clutch.
