Subtract the weighted measurement the second measurement from the unloaded measurement the first measurement to obtain your free sag value. Ideally, the number you get after doing the math should be around 10 percent of your quad’s total suspension travel example: 1 inch of sag for 10 inches of total suspension travel. You can start by setting the compression at full soft. Ride the ATV for a short while. Then begin to ride over small bumps. Begin to adjust the shocks to absorb the bumps without feeling mushy. As you adjust the compression on the shocks, gradually begin moving up to bigger bumps and jumps. Every time you progress to larger jumps amd bumps readjust the shocks. Keep doing this until you reach the point where you have reached YOUR personal limit of bumps or jumping safely while using all the travel in the shocks. It’s even ok if you allow the shocks to bottom out “slightly” as you land your largest jumpSetting the rebound at full hard slows the return of the shock to it’s normal position. At this setting as a rider speeds over bumps the shocks may not return to position fast enough causing the shocks “pack up”.
