It is proper that thanks be given to Cyclerob and Mikecam for their inspiration and help in this project.
Place a towel over the tank to save your marriage, then engrave the handguards to save your sanity when you reinstall them next winter if you remove them in spring. Clip the cable ties on the handlebars.

Now insert the fillister (cap head) screw through the larger of the clamp halves on top and thread it 3 or 4 turns into the smaller half on the bottom. Then loosen the bar end screws (5mm hex), they are torqued to 20 Nm.
Decision time. Depending upon your setup you may have to either raise or lower the clutch and brake line banjos, and this may require cutting the tabs near them. I believe it is my bar-backs that made it impossible to position them inside the handguards as per the included manual's instructions, so I raised mine to place them outside, while the cables and wires fell naturally into place inside. Note: loosen the banjos just enough to move them.
Edit: As noted later in this thread, an option is to not remove the tabs but rather to Dremel out a portion of the handguard to allow the hydraulic lines to pass through. You will have to decide what is right for you.
This is the clutch side banjo tab that I just Dremeled off. A hacksaw will do, but either way apply tape to protect nearby wires and cables. Banjos torque to 18 Nm.
Edit: You don't have to cut the tabs off if you are keeping the hydraulic line inside the handguard, you can Dremel out a portion of the handguard to avoid chaffing the line. If you put them on the outside only a BMW tech would know the lines had been moved and the "factory" look is maintained. If you loosen the banjos you should bleed the front brake and clutch.

Here is the raised brake banjo after the tab is cutoff. And a little flat black paint on both satisfied my little OC disorder.
The handguard goes outside the clamps with the threaded insert going in from the top and the torx T30 screwing in from the bottom. All the T30s torque to 5 Nm. A longer 5mm hex is included for the bar ends, torque it to 20 Nm.
Lastly, look everything over for interference, making sure the levers are free and the controls function normally, then torque to the amounts above. Check for controls function again after tightening.
Clean your tools and put them away. Go inside and have a beer; it's too cold to ride anyway
