The suspension stiffness does not depend on the spring preload adjustment, even if you completely loosen it, the spring will still be loose but it will not become softer. Correct me if I'm wrong, but YSS shock absorbers only have adjustments for spring preload and rebound, and I get a bit confused when I hear about damping. Regarding the rebound adjustment, 15 clicks are too stiff, resulting in more confident steering, while 5.4.3 clicks are softer but not as soft as the OEM, resulting in less confident steering.
 
Like I said a “Black Art”! You are right YSS only have Preload, Rebound and ride height adjustment. But getting all three to work in unison is the magic trick. The WP shock I had on my 1200 Daytona also had Compression adjustment as well, even more confusing!
I’ll start by adjusting the ride height and take it from there. As I have them at the moment, there doesn’t really seem to be much give and a bit harsh going over a bit of rough tarmac. I always found by experience and told by WP, the less preload, the softer the ride.
So for the time being, I’ll carry on with the route I’m going and report back soonest.
