            Once the frame covers are off, remove the 4 mm allen seat bolts on both sides of the seat. Use the 4 mm allen wrench to turn the screws counter-clockwise until they come off.

            Lift the front of the seat, then pull it off the frame.

Thanks . I have to reassemble the tank and I was not the one that took it apart so this tutorial is quite helpful. I had to buy a new rubber tank mount as they fall off easily also.
