Reading the threat with Piedrodn about first gear jump out, a lot of replies about clutch operation and stopped at lights, so instead of hi jacking a thread I through I start a new thread on clutches and stops.
There is a big debate on clutch plates and heavy Norton/Commando clutches, what plates are used for best lightness etc as well putting the bike in neutral when stopped at lights, everyone seems to have different views of that subject, whether in neutral or in gear with clutch in.

I start with clutch plates, heavy or light, I am still running the original clutch plates from the factory from new (48+ years now), my clutch has always been light, one finger if I wanted too light, but of course when riding I use all my 4 fingers on the clutch lever when using it, my clutch has over 160k miles on it and my Norton has been an everyday rider most of its life except for down times and upgrades as happens with a near 50 year old bike (74 850) the only thing I have replaced in my clutch is the clutch centre, new pressure plate and ven clutch cable and running ATF fluid in the primary, I use to go through broken clutch cable a fair bit in my early days till I started to put grease on the cable end that runs through the adjuster, haven't broken one since, about 40 years now.
There was 3 years when I ran different fiber clutch plates when I misplaced my original clutch plates when doing the Featherbed conversion back in 82, was in an oil filled container with an old primary chain on top of it stuck under my work bench and I was running a belt drive at the time, I was still using the belt drive with the original clutch plates for a few years after but had a quick bite with the bronze plates, but I started to have troubles with the belt drive so ended back to chain primary.
I have never done the stack height with my clutch, no problems with sticking clutch plates since using ATF fluid in my primary, have never had GB fluid migrate to my clutch and not using a clutch seal on the rod, I just don't over fill my GB and I put grease on the clutch rod when it's out for clutch maintenance and is the only time I have to adjust the clutch adjustments.
My gearbox has only been rebuilt when the dreaded layshaft bearing blew, but the kick start gear has been replace from wear with the KS pawl and broken KS shaft where the pawl mounts, I can't understand why most have heavy clutch pull and why so many don't like the bronze clutch plates as I have never had any problems with mine and such long life with trouble free clutch use.

Now for the debate on whether stopping at lights with the bike in neutral or with the clutch and in gear, after owning and riding British bikes for 50 years I always stop at lights with clutch engaged and in gear, the debate about cables breaking or burning out clutches, really, I am always ready to go as soon as the lights change the only time I do engage neutral if I know the lights take longer to change but will engage first before they change if I go down that road very rare I put any of my bikes in neutral at lights, as for the idea of a clutch cable breaking while in gear, well I always have my hand on the front brake while at lights, common sense really and my Norton has always had a light clutch and my 1200 Thruxton has an even lighter clutch.
I have also watch other bikers at traffic light and seen so many when the light change and they have to engage first gear and slow to doing that and being rush so many stuffing up and snuffing it and cars behind then starting to move, and to be honest I don't ever remember snuffing any of my bikes at lights.
In my own opinion I think it's more dangerous stopping at lights in neutral and what about the ones with clutch problems with engaging neutral in the first place or engaging first gear for that matter, no for me hand on clutch and in gear and ready to go for a quick take off.

I know lots are going to have different opinions on this matter, but hey I love a good debate, and don't get upset or rude if others have different opinions to your own.

And the reason why???
On a lot of old bikes especially Brit bikes the clutch will start to cook up loosing clutch adjustment
Also the clutch pushrod can burn out hence the SRM clutch pressure plate with a pushrod bearing conversion for unit and pre unit triumph and BSAs that stops the pushrod burning up
On my old Ducati 860 I used to dread pulling up at a set of lights in gear,coz there's no way I'd find neutral and if the lights didn't change pretty quick it'd drag you across the junction if you didn't hold the front brake
Now I don't know if this is typical of ducatis of this era or just my one?

My C11 slowly loses its clutch for unknown reasons if used too much in town, especially on a hot day. I've been unable to diagnose why. It works quite well if only used occasionally.
 
I am exactly the opposite of you Ash. I click neutral as I come up to a traffic light if I know I'm going to have to wait a certain amount of time for the light to change. If I come to a stop sign, I hold the clutch without going to neutral because I'm not going to have to wait any significant amount of time. I do have a reasonably light pull now. I've had it previously set for an extremely light pull and I thought the clutch slipped a bit so I readjusted the stack height to get a somewhat light pull but one that never slips... I have clean dry clutch plates with a dynodave clutch rod seal and a CNW belt drive.

I think if you hold the clutch in then the clutch rod is heating up while its holding tension on the spinning diaphragm, and the cable is also under tension the whole time, plus both my hands are occupied with throttle and clutch, so I don't have a free hand to check that my zipper pockets are still zipped or flip up my visor if I'm wearing a full face helmet to let out foggy breath.

Personally, I just do it my way...... I'm not saying that the way you do it is wrong...... I've broken a few clutch cables, over the 48 years I've owned this bike.... so it's probably just habit
 
Slipping it into neutral while sitting at lights or traffic roadworks stops the clutch plates catering on the clutch centre, ie no load.
 
Purely for mechanical sympathy I would not sit stationary in gear with a clutch pulled in for any length of time
The thought of drag on the clutch plates
The friction on the clutch pushrod
The strain on the clutch cable etc
And the strain on my left wrist (commando not included) they don't strain your wrist
As said some bikes it's ok others it's not
Personally I don't leave a bike or a car in gear with the clutch in

Most BSA unit singles I have owned are like this
As the clutch starts to heat up I adjust the clutch cable on the fly
Just so I can select neutral
 
No matter what we all do there prob not a right way or wrong way, its more to do with what we think is best, as I say my clutch hasn't burned up in 47+ years, my clutch rod hasn't got heat damage, but I do rub grease on the rod when I have it out, also stops any GB oil going down into the clutch and my clutch centre was only replaced for the first time in 40+years with some notches wear, as for clutch drag never had that problem, if I did I just adjust the clutch, I have always had a light clutch without any slippage, use too in the early days till I found the right oil for the primary.
Most clutch cables break at the nipple where it runs through the adjuster and I went through a few in my early days, but putting grease where the cable runs through the adjuster I haven't broken a cable since, so all my bikes get the same treatment and is part of my maintenance when doing oil changes, a dab of grease is all that is needed.

There were BSAs that used Neoprene (I think) lining material, which swelled up when warm, reducing the effective pressure plate lift.
 
R1250gs. If I stand for any time with the clutch in, I can smell the clutch.
 
I've never put a Norton Commando or unit construction Triumph, or BSA in neutral at a stop light - never even thought to!
Some of this depends on where you ride
I cross London which is the most traffic congested city in the world

As a long time Bonneville owner, I quickly learned the knack of finding neutral while coming to a stop. There's so much going against Triumph clutches, it was just accepted back in the day that they drag.
I went through a stack of new T140 pressure plates at the local shop a few years ago, and none of them would lie flat on the counter - utter junk, so SRM to the rescue here, too.
Add to that the wear on the clutch shock absorber, tweaking the 3 allegedly self-locking spring tension screws, plus lightly warped plates... the Commando clutch is genius in comparison.
My Ducatis are more a case of preventing carpal tunnel syndrome - The Italians clearly had a robust view on clutch lightness, which probably involved the word 'macho'.
My experience is it doesn't drag, but by god its heavy!
Extended actuating arms coupled with lighter springs and friction plates with reduced area are now available (similar to these: https://www.rgmnorton.co.uk/buy/clutch-plate-sintered-bronze-special-hi-torque-3-2mm_851.htm).

Apologies for thread drift...
 
For me it's just about how easy it is to find neutral on the bike I'm riding. Prefer a cool clutch.
