Contrary to popular option, setting the sag with the preload adjusters does very little to make the suspension harsh/stiff or soft. What is actually does is to raise or lower the suspension so it has equal chance to avoid topping out or bottoming out.
You want about 40mm sag from wheel-in-the-air to you sitting on the bike in full gear. Use the same 40mm for front and rear. Readjust as the suspension breaks in and frees up.
Front...put a cable tie around the inner fork tube. With the front tire in the air, slide the tie against the seal. Get on the bike, center it, jiggle a bit to settle the suspension. Get off. Measure how much it was pushed down. If it is less than 40 mm, lossen the preload adjusters. Tighten if more than 40. Try again. If you can't get to 40mm difference, contact Rich Desmond at Sonic Springs for springs that suit your loaded riding weight. Changing the springs on the DL1000A with the inverted forks is probably a professional job.
Rear...you want a helper. Raise the rear tire off the surface. Measure from the axle to a point on the fender. Get on, jiggle, measure. Adjust the rear preload adjusters to get to about 40mm difference.
The forks have compression (rate of compression) and rebound (rate of extension) damping adjusters. The rear has a rebound damping adjuster. I loosened the front compression adjusters two clicks at a time on a bumpy road until it felt mushy, then tightened them one click until it felt good. I loosened the front rebound adjusters until it felt bouncy, then tightened until they felt good. Ditto for the rear rebound adjuster.
Readjust everything as the suspension breaks in.
