Brake bleeding (again) arghhh help.

Yeah two lines, longest to the caliper left side of bike.
Yep faired bike. It's on the side stand.
With regards the rubber pipe to the res, the reservoir on my bike suffered platic fatigue where it mounted to the reservoir mounting bracket, so I got one of ebay. However, it was listed as an 05 sv but is not, so I made up a bracket and mounted it. Thing is the outlet on the res is a bigger diameter than the inlet on top the m/c. Not sure if this would have any effect though.

Should be fine then, the main issue would usually be an obvious place for air to get trapped. If the rubber hose has a high point that is higher than the res connection for example. Air rises upwards so you need to ensure an upwards path for it to follow unless you are using bleed pumps etc to feed the fluid under pressure.

But air trapped above the master cylinder would not affect braking - unless through bleeding or thermal contraction, the air gets sucked into the m/c.

Thats totally true, it can just slow down the bleeding process sometimes.

I too recently had a brake bleeding issue, never had one before. The pads were pushed out against the disc but could get no resistance at the lever. I tried everything including taking off the lever and holding it up in the air to ensure it was highest point in the system.

In the end I pushed the pistons back into the callipers, which forced brake fluid back up the hoses. That brought out what I can only describe as pepsi brake fluid, it was so aerated! You might try that or using a syringe to force brake fluid up from the bleed nipple. It worked for me.

Ta very much, all done and dusted now.
Tried your method flymo but after 10 mins no sign of fluid drop in the res or any coming through the bleed nipple so thought I'd crack on with the usual method.
Got some good feel through the lever very soon after, don't know if this was down to your tip or whether it was coincidence and it was nearly there already or not, but cheers for your input folks.
