You can usually bleed a top hose by simply installing the hose, filling the resevoir and slowly working the lever. Leave the cover off and watch for bubbles. This works best with the handlebar at full lock left, which gets the master cylinder at the highest point in the system. Be careful: pulling the lever too quickly will squirt fluid into the air and then on to your body work. When the bubbles stop rising, adjust the fluid level, put the cover on, and leave the bike on the side stand, again with handlebar at full lock left. This should get any final bubbles out.
