I just got a Triumph leather gas tank cover (with handy pocket to put my cell phone) for my '05 SM. So from the picture it looked like a no-brainer to install (just fit it around the center of the tank and tie down the end by the seat)....but nooooo. Does the whole top of the tank have to be removed to fit the tank cover? Anybody do it themselves? Why does everything have to be so %#$@ over-engineered? OK, I'm better now, thanks.
