OK, so I removed the old rubber hoses and put some Goodrdige ones (2nd hand) on at the weekend, managed to bleed them out with nothing more flash then 2 x half metres of clear tubing and 2 empty coffee jars.
Gravity and patience play their part here, after some advice from a bike mechanic I know and he was right.
Only problem I have is the lines I bought are a 1-2 set-up using another original Yamaha splitter and the top line to the cylinder is too long in my opinion, has a strange route around the fork leg, but doesn't foul anywhere on any lock, unlike my throttle cables appear to on left lock...
New fluid, lines and 8 moving pistons have improved the brakes somewhat!
