The preload changes the spring mounting point up or down. That's what it does. It makes the bike sit higher or lower so you, at your loaded riding weight, has about an equal chance of neither bottoming out nor topping out. Forget the factory settings unless you weight the same as the factory test rider.
For the front, put a cable tie around one inner fork tube. With the front wheel off the ground slide the tie next to the seal. Get on, get centered, giggle a bit to settle the suspension. Get off, raise the front wheel off the ground and measure how far down the tie slid. Adjust the preload to get about 40 mm.
Same idea on the rear, measure from the axle to a point on the fender, shoot for 40 mm. A helper is almost necessary.
The rear has a rebound adjuster. That controls how fast the shock extends. Back it off one notch at a time until the rear feels bouncy while you ride an undulating road, then tighten it slightly until it feels good.
