My little build

[BMW Alpina]

Bought a pneumatic bleeder to get fluid in the system and I’ve had no luck

Something must be blocking the path of the fluid.
Questions:
a. Did you use any quick bleeder valve? (check to make sure it work)
b. Check the banjo bolts does not have any dirt in the small holes/pathways
c. Check the hose (and the banjos) does not have any blockage due to dirt going into it
d. Check the slave cylinder does not have any pathway block
e. Check the fluid reservoir and it's short rubber hose to the clutch MC does not have any blockage
f. Check the clutch MC for any sign of blockage on where it connect with the banjo/hose
g. Also disconnect the hose from the clutch MC, then fill the fluid reservoir and squezze the clutch lever. See if it squirt the fluid out. If it is then it should works fine.

In summary, both the clutch MC and slave are just hydraulic device with hoses to transfer the fluid.

I think you will find it will be something simple
Once the blockage clears you will be on your way in no time
By the way I personally have never found the vacuum method to work well

I have the same issue with my clutch. The vacuum bleeding doesn't work for me either. I need to use forced fluid method using a large syringe (like the ones at the auto parts store and/or the grocery store cooking section). Make sure to get the biggest one you can find.

When I used my vacuum pump, I need to press the "black rubber piece" at the end of the vacuum hose that goes onto your bleeder valve with my finger to make sure it is really sealed, then it works right away.
Here is the vacuum pumps that I used: https://www.amazon.com/gp/product/B00OM751EC/


But in order for it to work well, you also need a strong compressor and I choose this Makita compressor because my smaller compressor just don't have enough air pressure (PSI) and consistent air flow (CFM or Cubic Foot per Minute):

Took the master off and there was some sort of blockage where the reservoir tube goes into the master. I tested it with my hand vacuum pump. I fired up my compressor and blew air threw the master and it seemed to clear it up. Have to run out now when I get back later I will hook everything up.

Nice compressor H

That is a nice compressor. Got everything done, blowing air through the master cleared it up. I put fluid in it and let me tell you the pneumatic bleeder is amazing I was done in like 5 minutes. Clutch feels better than it did before

Update!!! Bike is running strong the rear end feels great and my rear break works better than it did before. Getting the bike tuned really cleared things up. Throttle is very smooth, got her up to about 150 and nothing went wrong lol
