With my setting on one line showing on the front to decrease dive when braking. The rear set on standard 2 setting, three was much to harsh. This combo seemed to work well for me. Experiment with different setting until you feel the front reacts best with the rear.
With the new tires i have bumped up air pressure to 34/38.
Pre-load has no effect on compression damping (and therefore brake dive). If we had fully-adjustable forks up front, you'd want to up the compression damping to combat brake dive, but we don't, so all you're really doing is reducing your ride height and reducing your fork's range of travel. I'm not sure if we have progressive springs, but if we do, you may also be unnecessarily increasing the harshness of your ride by pushing the spring into the stiffer progressive rate sooner.
I run recommended tire pressures (36psi front), with front pre-load set for my weight (220+lbs w/gear, right at 2nd line) and experience very little brake dive.
Preload affects at what force spring compression will commence. This is also affected by the load that the bike carries. With a large pillion load the bikes rear suspension will operate at lighter (external) forces than unloaded. This will delay initial displacement but, as you say, after that damping forces become the only player. Therefore Honda (and others) recommend higher preload settings for heavier loads. I found that the bike tended to "wallow", particularly leaned over and going over small road irregularities. A bit over active. Upping the rear preload one notch has made an improvement. There are so many variables to suspension set up. Most are not available on the CB. Not needed really as it's damn good as is. Thanks for that Honda.
Cheers

Cheers Thank you p, you saved me trying to type on this iPhone
