Was it off the Amoco Cadiz ?

Been there, done that.
Mine had two large shims installed. Initially, only put one back in as the other had fell in the oil tray. That is why it had a bit of play when installed and had to start again.

Been there, done that too - I wondered what that funny noise was as I was riding back from Dover one night 
Did mine a few weeks ago, warm one bit up cool one bit down, 
This seems to quite common. Does anyone have a view on how common it actually is? Is the quality of the replacement bearing better?
Was very common on the 1150's. So much that some would take a new bearing kit with them on a long trip 'just in case'
How long it's a piece of string... it seems dependent in a number of factors.
I replaced one that was causing a small vibration. With the wheel off, the rotation of the hub in the FD was rough.
2yrs later it failed with zero warning, just as I rolled if the train in Calais - documented on here... but I was carrying a spare bearing, seal and O-ring.
Maybe I did something wrong when I fitted the new bearing, but not quite sure what that might have been? The deal did get a bit of grit caught in it st one stage so was weeping, maybe that contributed?
The moral of that story is, if you're going any distance from home - yunno,Tesco or Starbucks - make sure you have a spare bearing and seal stashed somewhere in your luggage.

Are the replacement bearings better quality or does it remain an ongoing weakness. If it resolves the weskness then i guess it is worth doing pre emptively?
I used the OEM bearing... both times. I think the bearings are fine.
My guess is, that it's the final assembly pre-load in the bearing. Now that could be affected by a difference in dimension of the new bearing, since (if I remember correctly) some of the shims in there can be 0.05mm, which would probably also be a max tolerance on the bearing in production... So in theory they'r could be af much as 0.05mm worth of too much side loading, which eventually kills them?
I don't really know. But ultimately, it's the breakdown of the cage that does it...

I've never had the pleasure of replacing one of these bearings , but bear with me
Am I right in thinking the cage is only there to hold the ball bearings in place and make assembly easier? If so , would it be possible to remove the cage and insert the individual ball bearings into place?
I always used to do this with my BMX bikes-- a bit of grease to stick them in place, pop them in, sorted. The cage wasted enough space to allow an extra ball to be inserted. Just a thought.

Thought you were selling a 1150?
Very obviously.
Totally no! That cage is instrumental in the bearing assembly working. Full stop.I've never had the pleasure of replacing one of these bearings , but bear with me

Just a thought based on some limited experience, qualified in the first line of my post. The cage looks the same as the ones I referred to, hence the suggestion. The extra ballbearing , all things considered , has to be a good thing as it removes the flimsy cage which may be the root of the problem.
Slipperyeel has contributed to the thread and clarified it, thanks.

I am JB, I am.
Part of the plan was to keep it if I liked it enough and sell my LC while it's still worth something. Its a great bike, obviously been looked after. It runs just fine and is a lot more nimble than my 2005 R1200RT ever was, surprisingly so for a big lump. The seat is comfier than the so-called 'comfort seat' on my LC. Only problem I've had is it makes my hips ache, presumably due to the wide tank.
Aches aside, I would be happy to keep it but never mind.
