easy peasy man. two bolts.
what i would do, myself, is drain gas out the petcock if possible on reserve, the undo the tank and have a friend hold it kinda sideways so whatever gas is still in there is on the other side of the tunnel and remove the two bolts, pull, replace. minding your gaskets on installation.
i think trying to do it with the tank where it is will get gas everywhere.
thats what i've done on other bikes.
