I'll look through and see how different it is to the 2006 workshop manual we have in there.
I don't know in terms of the manual but I thought changes happened in the model around 2005, things like:
- metal to plastic tank (I think effects the location of the fuel pump/filter)
- 4 piston to 2 piston front calipers
- APTC clutch ... 5 speed to 6 (this may have been earlier)
Oh and at some stage the bikini fairing became stock.
