For a two week tour, I like LeeG's suggesting of paring the weight. Shouldn't be hard to do for a summer tour. 3.5 pounds of tent, 2.5 pound pad, 1 pound flannel sheet, 3 pounds of clothes, 10 pounds for water/misc. Leave the kitchen at home. Might have to adjust your route some, but heck, it'd still be two weeks on a road to somewhere, and you could brag about having done it with minimal gear and on the Alan.

Go to some backpacking sites for ideas on lightweight travel.

BTW, you can use waterproof stuff sacks for gear and bungie them to the rack sides. You really don't have to have panniers. Save about 3 pounds of weight that way.
