I used Igofar's instructions, and with very little edit, this made my job very easy.
1. Remove Seat(s)
2. Remove Left side cover (above knob) .
3. Unscrew the knob COMPLETELY (counter clockwise)
4. Notice the preload adjuster is on a bar, follow it up to the (1) 10mm bolt holding it in place, and remove it.
5. Notice the brake line is held in two small clips on the front of the rear fender, lift it out.
6. Pull the metal mounting rod towards you until in snaps out of its resting channel.
7. Turn the preload adjuster upside down.
8. Hold unit with large adjustable wrench, remove banjo bolt
9. Wrap a papertowel around bolt and both crush washers (leave washer in place so they seat the same way as before)
10. Dump ANY fluid or goop out of preload adjuster by turning upside down and screwing the knob ALL the way into the max position.
11. Unscrew Counterclockwise completely again.
12. Take chopstick, allen key, or small screw driver and PUSH the piston back as far as it will go (about 1 inch) You'll feel/hear it thunk.
13. Fill preload unit completely up with HYDRAULIC JACK OIL flush with the top. Let air bubbles rise, then top again.
14. Insert the bolt with washers still in place and snug down.
15. Turn the knob completely to the max setting again (clockwise)
16. Unscrew the knob completely again...
17. Dump oil out again, push piston back in again, fill with oil again. You just filled the line, and emptied the preload unit.
18. Fill the preload unit one last time, then insert the banjo bolt, check the direction of the line, hold it with your adjustable wrench and tighten the bolt firmly, but not too much, because it’s a hollow, soft bolt. You just want to seat the crush washers.
19. Now you should start feeling resistance about 1 or 2 clicks in.
20 STARTING POINT: From fully soft (counter clockwise - open) turn it clockwise 4 clicks, this means you'll get one with no resistance, and a couple with some resistance, then it will get firm. \
Start at 4 (default setting is 7 clicks or 3 and a half turns from fully open)
21. Now to to the right side of the bike, and find the hole in the frame that goes through to the bottom of the rear shock. If you check with a flashlight, you'll see a small punch mark on the screw and the frame for reference.
Gently turn the screw CLOCKWISE until it lightly seats (dots should match up)
Now, turn it COUNTERCLOCKWISE 1 and 1/2 turns ONLY (This is 3 half turns).
Default setting is 2 half turns out from seated if you want to go back.
Now go take the bike for a ride on some various types of roads (hwy, mountain, twisty etc.)
Check to see if your rising and falling as much as before, or how the wind affects your ride.
Just remember, It will behave differently than your used to, so be carefull and get used to it.
***Any suggestions are done at your own risk***disclaimer..dang lawyers etc.
Check your tire pressures before you go out. I run 40 front, 42 rear for a softer ride.
Hope this helps.
