Hey Paul another suggestion I learned from riding my supermotard bike, is if you skim the rear brake a little as you stop it can go a long way toward eliminating front end dive. It's hard for me to get used to as I tend to ignore the rear brake on a lot of bikes but this one is so heavy and the weight moves forward so much during braking that the rear really does help out. You might even be able to lighten up on the preload again.
Another way to go might be to put slightly heavier fork oil in. On my old Ducati, I put a bit heavier oil and a 1/4 inch spacer...well my dealer did, I just asked them too.
Personally I'm hoping that Racetech will make us a new sportier set of springs for the front and rear, as I think the bike would handle even better with a little stiffer/controlled setup.
Have you tried putting a tad bit more preload in the rear shock? I'm not sure how much it will help the front end issue, but you may find you'll get a more balanced ride front to back. Sometimes it's the rear that is the problem and not the front and vice versa. It may be the stock shock's bouncy nature and making the front act up a little.
Anyhow, I say fiddle a little, Back off the preload up front one turn and put in a turn or two on the rear.
I was considering buying Baron's heavier rear spring and putting it on my never-to-be-lowered bike to see if it stiffened up the ride in a controlled manner. Blah blah blah
