Thanks for the comments Ian; I'll pass them on to my "pissed off with the bloody thing and just want to get shot of it" owner.

I was quite pleasantly surprised by the Arrow I had for a year or so - it was a very nice bike to ride, and I'm a devoted 2 stroke sceptic. Cracked along nicely for a 250 and the handling was excellent.

The Arrow was a great little bike however the Leader definitely was an acquired taste (even no taste at all), but it`s amazing these days how much the old British stokers are worth. I refer of course to the Bantam which in my day was subject to much derision but now seems to have a cult like following

Is anyone aware of something like this that does work with bearings...?
 
On both my spoked rear wheels, the bearing on the drive side is just loose enough in the steel tube to be an MoT failure. Much bearing lock does the trick but it is not permanent and has to be redone every time the wheel is refitted.

I don't think they're recommended for that sort of application as the metal's very thin. Welding / metal spraying and turning back to size would be my approach.

Bit the bullet this morning and fitted the sleeves but not without problems, albeit of my making. Bear in mind I’m fitting two on a single journal.  Each sleeve has a flange upon which the installation cup locates, enabling the sleeve to be driven onto the shaft.  Said flange must be cut in one place if you want a straight sleeve. This enables you to peel the flange away.  I had to drill a hole in the installation cup to clear a protruding bolt, then use a socket of suitable diameter on the back of the cup.
 The first one went on without issue, so if you only have to fit one, job done.  
The second one needed to meet up flush with the first, so I attempted to fit it in reverse to the normal procedure, as removing the flange leaves a gap of about 1/8” or 3mm for you kids! Needless  to say, this didn’t work, so I had to revert to the proper method fitting the flange to the shaft which has a lead-in.  This is where I hit the problem.  These sleeves are tight, which, of course, is exactly what you want, so they require a firm blow to get them started, then, after checking its square, a few more whacks, and you’re there.  You think!  
In my case, when I removed the flange of the second sleeve, there wasn’t a 3mm gap, I’d  obviously misjudged it and found it had gone right up against, and ridden over the first by a few thou, so now I have to dress it in order to provide an even surface. I might get away with it but........
Pain in the proverbial I calls it!

Update: I dressed the second (outer) sleeve to give a satisfactory surface for the oil seal BUT found that I could move it, albeit with difficulty.
This is obviously a major concern as the seals will be a fair bit tighter than normal due to the increased diameter of the shaft. After a struggle, I managed to get the sleeve off, apply loctite and refit it. I'm not happy about this situation as the engine is going to be used by someone else, and at the moment am not sure if I'll go through with it. The alternative is expensive but will provide the best engineering solution to this problem. Trouble is, the owner doesn't want to spend even more money on it. I shall examine the shaft this morning and attempt to move the sleeve. If it moves, then this repair will not be implemented using these sleeves. As I said, one is fine, but two is probably not a good idea. If I had been able to buy a sleeve with a 25mm width it would have been perfect, but unfortunately only two widths are available in the diameter I need. If it was my bike, I'd probably machine the journal and make a one piece sleeve with a decent wall thickness, but it ain't so I won't.

From past experience George, I will only work on my own bikes now.

Wise decision, Darryl.  It’s always awkward when asked to help out, even more difficult when, having supplied the material, machinery and consumables, the recipient says “if I owe you anything, let me know”, then picks up the job and waltzes off!
With my current “job”, the owner is a really appreciative bloke and even if I scrap the sleeves, having spoken to him about it before buying them, I know he’ll pay me for them.
I recently made a special stud for a club member, using a piece of my diminishing stock of stainless steel.  He could have bought one from club spares but thought it too expensive, whereas mine, was a lot cheaper as payment has there been none.
I expect I’ll continue doing it though!

OK, so what's the worst scenario? If it moves a tad, you might get a slight leak. Yes I know it's a two stroke. Not going to kill the rider.

I once lent my spare battery to a friend as his had gone TU, just to get him out of trouble. Next moment he had sold the bike, with my battery. Angry I'd spent some time previously helping him sort out starting problems.

In the case of the Leader engine, the seals are vital to maintain crankcase pressure.  If one or other leaks, that cylinder is compromised and the swine won’t run properly- or at all.
Hence my trepidation.  Ian is an experienced Ariel man, and I’m sure he’ll put me right if I’m wrong.  The loctite has worked - the sleeve is secure.  I’m off to Carterton today, for a few days, so I’ll reflect on it.
