Remove the two bolts on the side of the seat(see pic,bolt 22),two bolts under the seat(7).Both 4mm allens.
Now lift up the rear cowling so the pin is clear of the rubber grommet in the subframe.Put a block of wood under the rear of the tank.(Its bolted to the seat)
Look underneath the tank where the seat joins,....there is a 17mm bolt,(5)....remove it and hey presto the seat is removed.
As above but with a couple of extra bolts under the pillion seat.
