Its actually a fairly big job to fit any tail tidy to an '08 R6, allow at least an hour, 2 cups of tea, 4 fags and a skinned knuckle or two!!
First remove both seats,
then the top shell of the tail, 6 plastic rivets and 1 allen bolt.
(To remove the rivet type clips, push in the center till it clicks then just lift out the whole clip. (to refit, push the center back up two clicks so it sticks out the top, refit and push the center flush to lock))
remove the cowling around the rider seat, 4 plastic 1/4 turn screw type clips, 2 plastic rivets underneath at front and 4 screws underneath.
remove alloy plate, 4 screws.
remove pillion seat lock bar, 2 allen bolts and R clip (pay attention to how the spring is seated and make sure not to loose the white nylon shim under the bracket)
unclip the ECU from the tray, then release the 1 large black clip underneath (use a flat screwdriver to slide under center of clip, there are 2 cut outs for this, and pry up center to release then lift out) this finally releases the black tray (enough) to access the 4 bolts holding on the number plate bracket!!!
then you've just gotta refit it all in reverse.
Have fun!!
