Good job layin' it out Pacman but you missed one important point on the difference between '01 and '02 bikes bro. In '01 the tail section and hump did not match the "beak" in color. See yer photo of fatjap's ride for an example. In '02 the beak and tail section/hump matched in color. See MikesHardware's original photo for an example.
There may also be some slight differences elsewhere (paint line on the tank?
) but if no paintwork has been done and it's a US bike, the tail section/hump/beak match/mismatch thing is the easiest way to tell.
