Another update. I still had spongy front brake lever. never had a problem with the rear brake. I followed 2daMax procedure to rotate the rear wheel during the cycling of the abs pump. After the cycle, I heard a click from the abs pump and the front lever is now firm like new. That sounded like a stuck valve becoming freed up...
Just like that and out of no where, the front brake lever is acting normal and is very firm. The rear is firm as well. I am happy about this but WTH.
I've cycled the pump at least 30 times and bled 3 pints of fluid through the system.
Now, i notice while on the center stand, i can grab the front lever but the rear wheel can still rotate freely. Does that seem normal? i expected the unified braking system to grab the rear wheel as well.
Glad you are making headway. If It was stuck valve in the ABS pump, I am guessing you are still on borrowed time with the pump. YMMV

Don't trust that everything is fine...try the system many times in safe places. There have been cases of spongy brakes, "but" the rear ones... the failure of a front brake (70% of the brake system), I don't think I have read about it before in this forum, so we don't know if that valve can get stuck again, and leave you with a spongy brake, in the least appropriate place and time (for example... that your wife in the car is coming from the front, and you are going in the opposite direction with your girlfriend and you see her and need to brake and turn so that she doesn't see you)... you can lose the house for a spongy brake:)
