Sal, this isn't a recommendation but it's what I do. I'm a bigger guy (roughly 260 lbs with all my riding gear) and I run Spitfires with 36 psi front and 38 psi rear solo or 40 psi rear with a passenger. I also run Lester wheels. I find that I like the handling much better at those pressures. They are much higher than the stock pressures given above, so proceed at your own risk. As far as shocks go, if you still have stockers, put them in a box on the shelf and treat yourself to some Progressives or Ikons or Racetechs.
