Why would a torsion bar be any more susceptible to ageing than a spring?.....after all, a torsion bar is essentially an unwound spring and twists in exactly the same way.......unless someone knows different?

Apologies for the delay in replying..... self isolation changes the way you do things and time just flies by....which is just as well really.
Thank you for those suggestions......the Yamaha indicator clamp is very similar, but sufficiently different for me to try to find (or make) as close a match as I can.
That clamp you have Ash looks properly strong, you could hang a boat from that..... all suggestions much appreciated as I might end up going for one of them......in the meantime, I think I have some strip stainless than might do the job....and I can mirror polish that, so I'll have a crack at making one while keeping an eye out for an original.
Many thanks...........Mick.

Thanks for that.... but I don't think a P clip is strong enough.........the Craven carrier clip, on the other hand, looks just right....but the diameter is too small ..... Maybe I'll just have to make one..... no excuses at the moment, plenty of time in hand.  Mick.

Thank you for that......I had a look but nothing quite right...... I think these things were really common years ago, but I might be looking for something that doesn't exist any more. Obscure parts are usually out there, but it's knowing where to look or a specific name for the part, so fingers crossed someone might just recognise that style of clamp...it's as crude as they get, but hopefully, one might turn up before I try to make one from strip stainless....what could possibly go wrong?  Mick.

Hi all, this is a bit left field for this forum.......but I have a Yamaha XS2 and these things were fitted with clamp-on mirrors back in the day....no threaded perches on the switchgear until the next model.
I have a pair of correct mirrors and one clamp...... I need a simple handlebar clamp as per the ones in this photo....ideally from the UK or EU......you might imagine these would be an easy thing to find, but I have wasted a couple of evenings hunting and found nothing apart from Harley parts in the US and they use fatter bars so no good anyway.
Has anyone seen any such clamps around?.......Mick.

Having spent what seemed like an age learning Construction and Use, as I recall it, there is a specific tolerance for over reading, but none at all for under reading......that is, your speedo should never indicate you are travelling slower than your actual speed.
That is why your sat nav will invariably show your true speed as a few mph slower than the vehicles speedo......I've never actually come across a speedo that under reads.....bit of a risky thing to have these days....so that merits sorting out.

Fluorescent......are they going to glow faintly in the dark?
Top job as usual Ash.....what made you think of fluorescent pigment powder?.
For reference, there is a company called Games Workshop (my son used to play with this stuff, it's all about painting little metal figures) who sell a range of paints in plastic Humbrol sized pots.... the beauty of it is, their range of colours is (or was) huge....and includes numerous shades of reds and orange.
Added to that, the paint is acrylic, so it's simple to wipe clean any overspill with a damp cloth or finger, no harm will come to the underlying paint as there is no solvent involved, the coverage is very good, one coat is usually enough, it dries very quickly and once dry it's there for good, super durable......it could have been made for our purposes.

Wow!.......it looks like they can work wonders........I still haven't sent them my XS2 cylinder because a spare turned up, but looking at that, perhaps I should..........very glad it worked out for you.

Really interesting stuff, thanks Ash..... I used to have a local plater (chrome and Zinc) who had a rotating drum for zinc plating small parts....they didn't need to be wired and they self 'burnished' as they tumbled.....the results were superb.... and quick. This was a bloke who would recreate linishing marks in the chrome on Jap rims....every other plater I've ever met only wants to do the bathroom tap finish.
Sadly.....he closed down and the only remaining local plater which is a far larger outfit does everything by hand, each part including spoke nipples, tiny nuts etc is wired, it must take forever, I can't understand why a business would continue to use such an archaic method for small parts.....I always prep them, so I'll try your method for my next batch.

A few years ago I was lucky enough to buy a 1976 CB400f, one owner from new and just 4,000m, which had been in storage since 1978 and was completely original and untouched. As a bonus, the old chap, who I knew about 30 years previously had thoroughly drained both the tank and the carbs.....happy days.

I recall having a conversation with Ash about the finish on the fasteners and plated hardware...... what I found is, many fasteners that appear to be plain silver bright zinc reveal yellow passivated threads when removed..that being their original finish.
I'm happy to be corrected but my understanding of yellow passivate is, the item in question gets zinc plated and as soon as it is removed from the plating bath it is further dipped into the orange passivating solution, giving that lovely pale yellow finish. But that finish is micro thin, hence, as it wears away with time and use, the silver BZP below becomes aparrent and it's hard unless you are the king of anoraks to remember what was there.

Here are a couple of photos of my carbs as they came off the bike and after half an inch of fluff and compacted dust had been removed. look closely at some of the screws and fittings and you will see traces of yellow passivate. I recall concluding that pretty much everything on those carbs had received a passivate coating and that is how I restored them, although I don't have any decent photos of the finished carbs.
I'm always happy to be corrected, but that was my take on this subject........Mick.

I've always found this bloke's smug, self satisfied, self promoting magazine articles intensely annoying...... I had no idea he produced videos that are even more irritating........thanks for that  Mick.

No guarantees of course, but I hope it works for you....they do motorcycle cylinders, so provided there is nothing exceptional or unusual or the damage is in the wrong spot I would hope they can do it for you......I'd be interested to know how you get on.

Send a photo of the unit and the damage to past parts http://www.pastparts.co.uk/They bore out and re sleeve master cylinders in stainless steel and return them with the original bore size, so depending on where and what the damage is, it might not matter.....you have nothing to lose by asking. Incidentally, the price to re sleeve my XS2 master cylinder was £45 plus Vat and return postage. Mick.

I would hate to be the author of classic bike magazine articles, they will be pored over by anoraks (you and me ) who will instantly spot the flaws in them.....and very often say so, it's not possible to get everything exactly right when it's a broad subject. There are probably quite a few CB750s running about sporting age related G plates, and rightly so because they will be 1969 sandcast or very early diecast bikes, but none of them will be UK originals. The irony is, if your bike or mine were imported now, they would probably receive G plates from the DVLA simply because they were manufactured in October 1969......not that it matters, but it gives us something to talk about.

The double-cut front guard is very rare and used ones are ££££ ..even the Yamiya repro is over £1200 landed in the UK. How much!.....I've got a decent original spare double-cut greased up and hanging in my garage.......perhaps I ought to sell it! Back to the Brighton bike though....I was pleased to see he had a second tank sprayed and retained the original, I'd like to think he might have done the same with the seat....it seems to be very different to the auction photos which is a real shame as it is (or was ) a unique part......likewise I can't understand why he didn't snap up the original master cylinder and top brake line when it was offered as it was a once-only opportunity. Did anyone else notice the mention of G registration UK bikes?.....never heard of one of those, although there are probably quite a few imported sand cast bikes that wear a G plate....... and it looks like the front number plate is probably held on by magnets Ash...nice to see it's the original item. Mick.
