Power disc brake conversion problems

[Harley1650]

I'll start by saying I'm not a master mechanic, so hopefully my problem is simple. I bought a disc brake conversion kit, a dual master cylinder and a 7" dual diaphram booster. I installed new brake lines, a proportioning valve and a Summit brand line lock to the front brakes.

The problem is.....
I have no leaks,bled it numerous times with a power bleeder and all I have coming out is fluid. The brake pedal goes all the way to the floor, but it does have some brakes at the floor.

The kit had no destructions so I was winging it. At the rear of the booster is a threaded rod coming out of the booster. When I made a new pushrod from the pedal to this rod, I connected it between this rod and the pedal so it did not engage the booster. I guess I'm wondering if I need to tighten the rod so it engages the booster?? I hope this doesnt sound confusing but I sure could use some help......
