actually I'm not.. I know the knob on the bottom is rebound setting but I have never adjusted the spring preload w/the spanners.. it seems to me you'd need to pull the tank off then make a change.. if that isn't satisfactory you have to do it all over again? and again till it's right? that's all I'm asking.. I'm 150 pounds and I think it's still at the stock setting, where should i have it for my weight? Like I said, no complaints with the way it rides now, in fact this is the sweetest Guzzi I have had out of about 6.
