I just did the bars on my 09 which should be the same if that is the case then;
1st remove the cover plates.
2nd remove the 2 fastners on each bar. You will notice on the underside of the bar there are locator pins "be carefull with them".
You will also notice the plate clipped on below the stem with the corresponding holes which position the bars (there are three positions). Set the bars in the desired position (both bars have to be off in order to adjust the plate) reinstall the fasteners 47 ft-lb for the nut, 17 ft-lb for bolt, then the cover plates "done deal". Hope this does it for ya.
billyp - I have not moved mine yet but I have read that you need to remove the bolts from both sides before they will move. I hope someone posts instructions or photo's because I plan on moving mine also.I am sure other guys on this sight will be able to give you step by step instructions.
