That pic is actually from the parts fiche. Download the clutch mod instructions from here
as well as the service manual. The service manual discusses the clutch in three places within the Engine chapter, disassembly 3-18, inspection 3-44, and reassembly 3-93 (page numbers may vary slightly). The clutch mod instructions draw on the parts fiche and service manual pics. You need not do the basket drilling that is in the clutch mod but the K7 wave washer is highly recommended. It also uses a different/simpler method to set the clutch lifter pin height that doesn't require removing the hub/plates/pressure plate/etc. from the basket. The service manual method may
be better but it requires a bunch more disassembly/reassembly. Furthermore the instructions given to the dealer service people for checking the pin height are essentially identical to the clutch mod procedure. Adjusting the clutch lever is mentioned elsewhere in the service manual and has been discussed many times here.
