Hi,
Here is a link of the service manual.

The job is easy and you do not need spacial tools.
Remove the tank to avoid fuel spill, and lay the bike on the left side, than unbolt the bolts holding the clutch cover on the engine. Make sure you remember which comes from where as they are with different length.
It is a good idea to have a new gasket but if you do not, be careful when taking off the cover as the gasket is paper and you might damage it.
Now you will see the pressure plate held in place by five or six nuts, unscrew those and pull out the springs and the plate. Now you are ready to take out the clutch disks. Take each one-by-one remembering the order and beware that the last friction disc is thicker. Wash with brake cleaner spray and soak in oil (just put some oil in a bowl and submerge one by one each disk in, rib with fingers) you do that for friction discs only. Reassemble as you go.
Once ready put back the pressure plate, springs, nuts. The clutch cover comes next. Just as Pete says above "make sure the dot on the arm &
the dot on the case line up".
Pump the clutch few times, start the engine, pump again few times and you are ready to go.
Hope this helps.
