I can sympathize with your problem. Dehydration is a serious threat during summer riding. I made a hydration system that consists of a one gallon insulated Coleman water jug with 1/4 inch food grade clear plastic tubing and a camelback bite valve. I mad a fixture that bolts to the right rear crash bar and right passenger peg. When you raise the drinking spout on the Coleman gallon jug the opening is big enough you can force the tubing down the spout and into the jug. About six inches from bite valve i wrap the tubing with Velcro and secure it with small tie wraps. A small piece of Velcro with adhesive back stuck to the top of the gas door gives a place to put the hose when you are riding. I can fill the jug with ice and then water and I stay hydrated all day. Making the bracket to go on the crash bar and rear foot peg is the only fabricating required. I used this system for over six years with no problems.

Good Luck
