Put some thread sealer or grease on the bleeder bolt so no air can get through the threads. Crack open the banjo bolt at the master cylinder. Use a syringe or a mity-vac (in reverse) and push the fluid in from the bottom thru the bleeder bolt. It will push the air thru the caliper and up the line. Once you get fluid at the master, close the banjo and push a little more up into the reservoir. Take the syringe/mity-vac off, then bleed the system like you normally would. The "Reverse Bleeding" method just speeds everything up. Search Google for "Reverse Bleeding" +motorcycle. Tons of links.
