endless air bubbles in brakelines

Whats in a title?
I'm bleeding my front brakes on my 600 rr and it is seemingly endless. I have put through about 250ml. Still getting a lot of bubbles. I'm wondering if its sucking in air from somewhere. I'm using a bleeding bag and the lever to push the bubbles out.

Button up and try the brakes. Everyone thinks "air bubbles" are a problem. If you use a mityvac you will almost ALWAYS pull air around the connector or through the threads. It means nothing most of the time. Try the brakes.

is the bleeder at the master cylinder tight? possibly sucking through the threads on the screw?

I was thinking the same thing, here is one last observation, actuaply 2. When I let it sit for a second, it would take arounf three brake pumps to start showing air bubbles, and the second observation is that even after I tightened the nut, it would still show bubbles coming out..
