I've found wemoto do the swingarm bearings/bushes/seals in a kit delivered for under �30,which is much cheaper than suttons �112 probably plus vat price,although they don't do the tubes,which are cheap at around �6 each.
I'm doing a bit of research as all the linkage bearings/seals /tubes come to we'll over �200.
I've stripped this one and got almost all the bearing numbers (TA1720Z,TA1715Z and a hard to read one currently )and they can be bought much cheaper along with the seals. If this all works out the bill could be less than �90 as I'll probably still get the yamaha tubes.
I'll keep you posted on my progress.
