Dlaing, Thanks for chiming in. I had Guzzitech set me up with my penske based on my full gear weight, riding style etc. I have no idea what my spring # is but I weigh about 200# with gear. I havn't done a thing to the shock or front springs yet but plan on setting up sag when I get a better understanding on how to set it up , what it does to the riding characteristics, and what I'm missing out on by not doing it. The bike seems to ride fine and takes bumps fine, but I'm sure tweeking it would be optimal.
