Take the cover over the front sprocket off. Loosen the cable adjusters. The cable attaches to a lever arm under the front sprocket cover. Loosen the locknut, leave the wrench on the nut. Use a screwdriver to back off the slotted shaft end about two turns (counterclockwise). This ensures that the shaft is not in contact with the clutch. Now turn the shaft clockwise until you feel some resistance. Back off 1/4 turn. Leave the screwdriver in the slot (to keep it from moving) and tighten the lock nut. Now adjust the cables for 1/2" freeplay at the end of the clutch lever.
When I got the bike 35K ago, I was scared to work on it. Now I'm scared to let someone else do it. I've done the clutch adjustment before and it is just as the service manual (and you all) describe. My clutch doesn't slip (nor has it ever...well, except I did fry it a bit once in the mountains after being trailered and I didn't realize that there was no freeplay) and it is adjusted fine currently. I'm going to get a new cable soon as I am at the bitter end of the adjustment for freeplay by the sprocket with a bit left at the bar. I'm hoping not to get to learn how to install a new clutch before next spring.
