2006 DRZ 400s stock shock and spring - rear shock set up adjustments needed? Any great threads I should know about? Or is there someone that has an opinion? I know there are 3 adjusters- 2 up and one near bottom- not sure thier names or what they do. I weigh max 200lbs in gear. I ride hard offroad and hill climbs and sand- a dirt biker with a license plate - only a few minutes on road for every hour offroad.
