Being as my bike is new I did not need to set the suspension to factory settings, something I highly recommend if you purchased your bike used
then Basically I did this starting at the front at all times with any and all adjustments
Tech Tip - How To Set Motorcycle Suspension Static Sag

Then . Rather than just crank the preload I loosened off all the preload on the forks and then cranked them to the max to see how much adjustment I had available. I was surprised how little total adjustment there was left for me to use I then returned it to the original factory setting
It is important to remember that your forks are never really still even on the best roads So you need to have the preload set so the suspension will both contract AND expand to both absorb bumps and return the tyre to the road surface after the bump
I found that at almost 300 LBS with gear I was never going to get to the correct sag.
I also found that my bike at factory settings was tilting forward rather than being level front to back this effected both my steering geometry and shock absorbsion front and rear
I also felt the springs were so soft they're really barely able to hold up the bike
I needed more preload at both ends However if I set the Rear preload correctly I would again be transferring more weight to the front springs which were already over worked That was not good
So with that in mind I decided to try for a more level ride rather than correct sag at the back and too little at the front. But that is me
I then adjusted My compression and rebound damping to allow freer quicker response to both compression and release. I needed to relax both so that they could respond better to road bumps under all conditions both big and small. Too much compression damping and you are turning your forks into a solid stick Too little Damping you are being flung into the air as the spring extends undamped after the bump
It is a matter of taste and riding style. I am a pure street rider and may knee digging days are well behind me. However I still like a firm ride with good but not extreme corner handling.
With stock settings go for a shortish ride on a road you know well. Take notice of how you think the bike reacts
Is I too jarring. Too bouncy Does it skitter to the outside of a corner
Then go and set sag and compression and damping to what feels right in the shop
Once you are where you think you need to be go and ride the same road at the similar pace again note how the bike behaves. Still to jarring? try a little less comp damping Too bouncy try a little more
ONLY change one thing at a time Do not change everything all at once to save time you will not know what did what to the ride
My only other thing is Do Not listen to what other people say they did to their bike
Their bike is not your bike Their riding style in not your riding style They are not you
It is time consuming but well worth it and you get a day in the saddle enjoying your bike
wht could be better
If all else fails try to find a good shop that specializes in Suspension and go and see them They maybe able to use their knowledge to get you started. It is not really that hard and it is well worth it
