Oh and one more thing, don't leave the lever pulled in, just leave it normal so fluid can work its way in. In the pulled in position, the intake is closed to avoid pressure return and will not let fluid through.

You are on the right track there Kel, all you can do is tie the lever against the bar for at least 4 hours and that helps the air rise to the MC and when you release the lever the air goes into the MC and gently pull the lever and that air should come out.
When you start to get some pressure pump it till you get max pressure and tie the lever in.
Make sure the MC piston is returning far enough to let it get more fluid when it needs it

OK. Rick, back to the original plan then. Re clamped the lever to the bar. Will leave this overnight with a full Master Cylinder.
Lets see what happens.
Gee this has never been that difficult with any other bikes I've owned..

This is what I use to vacuum out an empty brake system with. Even works with small hydraulic clutch systems.

When you pull the lever in, the same as pushing your brake pedal down, you close the inlet port. ie: fluid getting into the master cylinder and air is forced down the line towards the caliper. If there is air trapped, there is no way it will gravity bleed that way. You have to keep the inlet port open if you want gravity bleeding which is in most times a very good solution for a stubborn bleeding situation.
Have been running a mechanical workshop for the last 20 years and we have come across many situations like this on worse setups, ie auto ABS systems. Can be a pain at times, but works. If you had a vacum bleeder, would have made life a lot easier, but then you don't wanna have to go out and buy a whole lot of stuff for a very simple situ. Either way, hope it works out.
