Who would know what I can to my rear shock/spring to soften it up? This is on a 2002 Polaris 800 XC SP. My problem is I weight 150 pounds and I can't get my sled to weight transfer. Or when I sit on the sled it will not sag at all. Should I look into getting a new spring or something else? Or does any one know of a place that can get parts to do this with or get suggestions from? I have already adjusted the suspension to soften it up. Thanks for the help.
