Hi All, I am searching to find a supplier for an engine and gearbox sprocket for a 1929 Norton Model 18. The engine shaft taper on these early bikes is smaller than the later machines and the Sturmey Archer gearbox spline is also smaller.

When out for a run to run in my 1960 Dominator 99 I heard a bit of a tapping sound, I thought a valve tappet needed adjusting.

Hello, I've been searching for GTX 20/50 and come to a dead end unless I import it, I've seen plenty of GTX 10/40 and Castrol XL 20/50 but I don't know what that is. Does anyone know if it's been superseded? 

Need some education with cylinder head for 1967 N15CS

What's going on with the offset counter bore, does it serve any purpose ? Looks like a squish band but what not full circle ?

The Dominator 99 I took over is fitted with bronze/steel clutch plates. (I assume sintered bronze).

I recently borrowed the 6v coils on my Mk3 to test on another bike. Now I've put them back on the Commando I have developed a serious backfire on one cylinder.

My Dominator will not idle at the correct slow speed.
It is considerably faster than it should be.
The slide is all the way down (no gap at all on the engine side).

Hi guy's need your help.

Hello all,

Recently, I bought a set of Model 50 crankcases. Am I right these are from a late alternator model and am I looking at a rev counter drive?

Cheers,

Hello wonderful helpful fellow Norton owners..
Reaching out for help and thoughts again please.. because I can't find this information in any reference books or pamphlets on the subject . 

In answer to Stu Rodgers question about a strange cambox in Roadholder 447 I submit the following.

Is it worth getting these serviced, new seals/pads etc and where would be the best place to send the caliper or would it be better to fit a different caliper with adaptor plate and if so then where best to obtain that?
Many thanks.

Hi. Can anyone advise me on whether it's possible to swap an 11/16ths output shaft and clutch set up for a 3/4 output shaft and clutch set up.

Hi all. I'm taking my Commando to the Colombres Rally in September. 
Plan is to trailer the bike from Lancaster to Portsmouth and then ride the bike onto the ferry to Santander.

I am replacing the dipper switch of my bike, but I am a bit confused on the right Lucas part to use, the dipper is all-in-one with the horn button or separate?

Where to get and should I use a solid Copper one or not ?

Hello, I bought some high level SS pipes for my 750 but a bit adjustment is needed to distance them from the side panels and to pull them down a bit to get the silencers to fit, the adjustment needs to be about an inch in both directions.

Kickstart return spring!

Good evening all, I'm hoping some light can be shed on an issue I currently have. I'm attempting to fit a new kickstart spring, the old one had snapped and appears to have a longer tang welded on.

Hello Folks

Hi - just finishing getting the Commando Mk3, elec start, 1976 road ready.

Photo shows four cam followers. 
I notice a chamfer down the length of the followers. Only one chamfer per follower. 
Do these come handed? 
Should these be fitted chamfer to chamfer? 

There are two unregistered one owner Commando's going to auction with push miles on them only. Anyone considering to bid on these will most probably need to check first that they can be registered.

I'm wondering if anyone out there in Commandoland knows where I can source an opposite handed disc-side slider from, for use as the 'other' fork leg, so that I can fit twin brake disks?

Hi guy's can anyone tell me how to measure the cutaway size on a amal concentric carb. In layman's terms please

Hi - I am trying to trace a link to a dealership(?) that I believe was located at 200 Greenwich High Rd in 1959. 
Does anyone have any knowledge regarding the owner etc... ?
Any help or observations gratefully received.
