Put your bike on the center stand and put a floor jack under the skip plate to lift the front wheel. Put pressure on the front brake line until you get the bars to stay straight. This will tell you how you need to zip tie the line.
At first I just used one zip tie on the holes in the frame. I'm wondering if there was supposed to be one to begin with. A lot of guys claim their bikes go straight. I added another one to the wire loom that goes through the cable organizer because it seemed like it put less stress on the brake line when putting the bars at full right lock.
My bike now goes straight as an arrow with hands off the bars.
