Thanks Dave and Olympus, the only reason I ask is because I have ordered a pair of premiers from Classic Bike Spares in Aus, and was told that the standard main jet is a 200.
200 according to Amal's information, 230 according to the Mk3 manual and riders manual.
Edit: 220 according to the Mk3 parts book.


When I took the original carbs off the bike, they also had 200 mains installed (I’ve only had the bike for a short while) so I’m wondering if the fuel here is different.
What are the carb numbers (LH and RH - 932/??)?


I’m using 95 Ron fuel ( no ethanol) the bike is a stock standard Mark3 with a ham can and points but I intend to change to a Pazon Altair soon.
A "ham can" isn't standard and what about the silencers/mufflers as the original black caps/bean cans usually get replaced with peashooters, etc.?
If so, then there's a good chance 200 is going to be too weak.

Hi L.A.B.
The numbers on the original carbs are 932 L34 and 932 R33. And I’m pretty sure that the mufflers are peashooters.

L34 and R33 are the correct carbs for a Mk3 and would normally have 230 (or 220) main jets as standard.
Somehow, Amal has the wrong carb numbers (932/42 & 43) and main jet specification (200) for the Mk3.
(932/24 in Mk3 parts book appears to be a typo)

And I’m pretty sure that the mufflers are peashooters.
Yes, so a ham can and peashooters probably need approximately 260 main jets.

It's worth noting that there are some quite restrictive peashooters out there as well as the open type.
The restrictive type have a smallish exit hole and are much quieter than the open type.

Thanks L.A.B., I will contact the supplier today and get him to change the main jet sizes before he sends them. And replace that missing bolt.
Really appreciate your help.
Pete.

Thanks Glen,
I’m pretty sure that mine are not restricted. She has a nice ‘note’ when I give the throttle a good twist.

The open ones are clearly open. You won't mistake them. When you pass someone wound up you will break their windows...

I have a 1290 Super Duke which has a link pipe fitted thar removes the cat/primary silencer with a short Remus can, it’s LOUD. However, Sandra reckons that the Commando is louder from the pillion perch so I guess my peashooters are the good ‘uns :)

My first Norton, I love the sound when I get behind it. Should be better when it’s running nice with the new carbs, and soon, new EI.

Respect Pete, you've worn the end off the PILLION footrest rubbers !!
Actually, if you carry a passenger regularly the ends of the rubbers break off! I know from experience. If you rotate them 90 degrees when they start to split you can get a bit more life out of them. I think you would run out of tyre before the footrest rubbers touched the road.

Years ago a friend of mine set out to find out what grounds first on his Roadster by leaning the bike ever further on a local road that had a nice sweeping bend. His discovery was that you fall off before anything grounds! An expensive lesson but luckily he was uninjured and the bike just a bit scuffed.
