Front braking is lost after changing lever.

First and foremost, has the wrong brake fluid being used when the master cylinder was replaced? DOT 4 is the correct fluid for these bikes or DOT 5.1. Do not use under any circumstance DOT 5.0 as this is a silicone based fluid and will turn to a jelly like substance after a while. It can also ruin your ABS module. DOT 5 is coloured purple (at least HD fluid is). Open the top cover of the master cylinder and inspect this. I have got seized ABS modules in the past due to poor servicing (brake fluid must be changed every two years as it absorbs water (DOT 5.0 does not)) causing corrosion in the module.

What module?

ABS?

There is no adjustment. The lever and the pivot pin are worn and should be replaced. Check the amount of up and down play in the lever and you'll probably have play there as well. If this isn't it, it's the front brake master cylinder that has the problem and it needs rebuilding.

Good Luck

This is by design. When you have new pads on the bike and a rotor within limits the lever has very limited travel before engaging.
As these parts wear the position of which the lever engages changes. Unless you know that at the last brake pad change the caliper was "centered" this could account for the travel and will result in premature wear on the components.
