Turn handlebars to far left, then look just below the Tach, on the right side for a small(chapstick-sized) tube that has a knurled flat-topped knob, wires and smaller tube running down to front brake calipers. The chapstick-sized tube is the brake fluid fill tube, you must use a turkey baster (syringe) to top off the brake resevoir. Also, look online for some Speed Bleeders, makes it a LOT easier pumping up the pressure and bleeding the brakes.
