On my 1990 CBR, the front of the gas tank is held down with two 8mm bolts. The rear of the tank hinges. The front is supported in the up position with a strut on the left hand side. You don't have to disconnect any wires or hoses. If yours doesn't have a strut, have someone hold it up (don't do it with a full tank) while you attach the straps together. Then bolt it down.
