It's real easy. Just remove the seat, and then all the bolts around the tank, (i think there is about 6 0r 8) then the sending unit wire, and then disconnect the fuel line. You may need to push the fuel line forwars slightly before the tank will come out. Slide the tank towards the pass side first with the fill cap off. Then when it comes through the grommet on the side put the cap back on.
Good luck!
Oh. and keep an eye out for the build sheet behind the gas tank. Make sure you save it if you find it back there.
