On 2007+ KGT I was able to bleed front and rear by just pumping the lever and cracking the nipple at the respective calipers with a hose immersed in a bottle with brake fluid, and a little topping off at the reservoirs. I did a pretty complete flush like that. The nipple at the master cylinder is for dealer/factory fill and is not needed for this.
Try not to snap off the bleed nipples if they are stuck tight. A little penetrating oil first helps. Speed bleeders make it even easier if your arms and legs won't reach the levers and nipples at the same time.
That's about it.
