Just following on from this as I still exploring all avenues....
Spoke to Yamaha Tech UK and they are saying completely the opposite to Tyres4bikes, Brooke,m Maxton, ketech, etc etc.. They have said all I need to do is have the right weight oil in there and the steps would be -
1. Drain the oil out of forks and leave to drain for a few hours.
2. Flush the forks with cheap 5w oil, and again leave to drain.
3. Then place correct amount of Kayaba 01 (from what I have found online this is 5w oil)
Then set the forks back to std setting (if not already) and work work from there.
Yamaha and Tyres4bikes have never heard of the cartridge tube wear, as per Maxton's statement. And as these replacement Stainless Steel tubes cost £100 plus vat per pair I am leaning away from going with them (Ktech was out of the window ages ago due to the new ludicrous price PDQ quoting @£750 fitted).
So now I am at the stage where I am strongly considering Tyres4bikes, as for £180 they will

- dissemble and clean all the internals.
- change the oil and dust seals.
- replace the fork oil with 7.5w.
- return postage.
