As mentioned before, I am very inexperienced with only recent significant track time. My 2000 426 is totally stock. I didn't set the sag but I did turn out 3 clicks on the suspension. While the suspension initially felt harsh, it seems it has broken in a bit and I have gotten used to it also. The one problem I have is with the front end on hard landings. Just feels hard coming down, with some wobble involved, on the bigger jumps with flat landings. I'm assuming this is what they call headshake? Is this a suspension issue, a handlebar issue, or a work out and get bigger forearms issue? I thought I had heard people say aluminum bars help to eliminate vibration, etc. Would this help my problem also?
