I did mine a few weeks back. PITA, but procedure was:

1) Lower LHS fairing off.
2) Clutch Slave off (three bolts - not actual entier removal off the hose!)
3) Remove Allen bolt (facing you) that connects shift rod to the gear change on the engine side
4) Remove sprocket cover
5) Loosen rear chain adjuster and give yourself as much slack as possible*
6) loosen off the allen bolts holding on the spar that the footrest attaches too - once done pull it towards you - BE CAREFUL, some of the bolts also hold the sidestand. You should be able to pull it towards you by 10mm or so.
7) Loosen the 10mm allen bolt in the sprocket shaft and remove sprocket (it'll still be fiddly and you'll swear alot).
8) Fit new sprocket -much easier than removal.
9) Tap bracket back in (I used a rubber mallet) and threadlock and retorque bolts (care as not all the torques are the same)
10) refit 4) to 1) above, torquing and threadlocking as you go.
11) Re-adjust chain tension.

*Be really careful with the LHS exhaust, as the loose chain will flop down and the pins can easily scratch the side of the exhaust - I wrapped the exhaust with a old towel.
Thank you for the excellent write-up.
I had a issue about unscrewing the Allen bolt that connects the shift rod and clutch change. It was too tight to handle and a bit damaged a little to remove it quickly. The bolt got an inner rounded deformation. Perhaps a service technician used a wrong torque one year ago.

Thanks for the great write up . I follow your steps and everything worked as described. The only comment I have is that if replacing sprockets and chain you don't have to do 6). You just cut your chain and after that the front sprocket slides right off. There is enough room to work it out of there . If you want to replace the sprockets only then I can see the need of having to undo the bolts holding the rear end.
Thanks for you write up again. It's amazing how new chain of better quality and everything adjusted by the manual changes the way bike feels and rides...
