I have a pretty good understanding of what the various suspension settings do but I'm having trouble applying that to improve my ride. I have OEM forks and Penske shock.
I have set front/rear sag to 40mm and have left that alone. I started in the middle of the range for compression and rebound damping settings and made small adjustments.
I'm at a point now where the suspension feels pretty good on smooth roads and it will absorb individual raised bumps and a series of small bumps well.
It does not handle dips in the pavement though. Riding off the lip of an asphalt overlay or off a raised bridge joint is jarring even though it looks like its only an inch high. The rear is rougher than the front. A sunken pavement patch will be rough dropping into it but the raised lip on the other side is smooth.
What should I adjust to make this better? Do I need to back off the rebound damping to get the suspension to extend faster to meet the pavement? Or back off compression to soak up the bump when the tire touches down? Both?

Start backing off compression over a known bump. Get it set right. Ride for awhile and see how it feel in corners and under hard acceleration.
Then, using above, play with rebound and see if it makes a difference.

Could you post your front and rear settings? I'd like to compare. I regularly change lanes over tall repaved highway lanes and don't even notice it.  |

I've got it pretty dialed in now. This is also the first time on any bike that I've noticed a change in ride when the tank is full vs. empty. When I was having fits with it, it was on empty. After I filled up it smoothed out. I don't recall this difference with the OEM shock, maybe because it just wasn't that great all the time.
I did set sag with a half tank per the recommendation in Stoltec's installation instructions.

Glad you got some positive results Toshi. Being that sensitve to weight though sure makes you wonder why. Maybe your settings still aren't fully optimized.
I keep thinking about Nick's comment about the Penske improvement drawing attention back to less than perfect forks. Supposedly the front is overly stiff, and a full tank might help to offset that. So, if that truly is the case, the fairly inexpensive Stoltec upgrade to the front could make it all come together regardless of how much fuel is in the tank. Going from full to empty right now is far from ideal for rider comfort.

tigershark You're right! Nick recommended the softer 0.85kg/mm fork springs for me. They're definitely an inexpensive upgrade but I'd need a few tools to be able to do this. I'm looking more into this now

Great! Doing the upgrade myself was why I didn't try it right away on mine, but you'll get there. I did have my settings as soft as they would go on the factory forks.
