Try holding slight pressure on the brake lever as you slightly loosen the hose banjo bolt at the master cylinder--look for bubbles as the lever is pulled back. Be sure to tighten the banjo bolt before you release the brake lever. Repeat this process at the right caliper then the left caliper, and finally at the bleeder screws under pressure. Air likes to hide in the banjo bolt. This also applies to the rear brake circuit as well. With oem brake hoses I'd recommend using hose pinch-off pliers to isolate each branch of the hydraulic circuit, but I woudnt do that with your SS lines.
Does your brake lever "pump-up" if you pull and release rapidly? If so, look at the caliper pistons being pulled back in their bores(Ive seen that). I did have an issue like that years ago with a GSXR-750--it was a bleeder valve atop the front master cylinder under a rubber boot. Ive also had to loosen and tighten under pressure the pipes at the ABS unit while checking for bubbles. I have had to, but Ive read that sometimes the ABS unit needs to be actuated to remove air. Ive recently flushed brake fluids in my '14 DL1000 and a friend's 'DL650, but I made sure the reservois didnt run dry at any time.
