This is REALLY helpful, but for me it raises a question. Several actually! I ride a 1200 FD, and am trying to get more comfortable on it. I'll probably put myself in the hands of a suspension guru at some point soon, but before I do I'd like to be a more knowledgable consumer of their services.
You say not to fiddle with damping adjustments until after "properly" setting sag. But how do you "properly" set sag? Do you mean setting it to stock specs? or to the 25% to 33% of suspension travel I've seen as a rule of thumb? or something else? (I now how to measure sag, I just don't know how to decide what to set the measurements to.)
Sag settings -- along with other means of changing front and rear ride height -- also have an effect on steering geometry (rake and trail). Is there similar guidance anywhere on how to "properly" set steering geometry and feel?
And finally, how do you know if your spring rates are too hard or too soft? How do you decide whether spring rate is a problem and whether stiffer or softer springs are worth the effort and money?
Thanks, VFRD, for whatever light you can shine on these subjects for me...
