In case that suspension does not consume the full travel, feeling the harsh and has a bad wheel traction during turns, then the hardness of the spring or compression is too high.
Reduce the pressure in suspension or replace spring with a softer or decrease the compression damping at high speed compresion which is in the final stroke or low speed compresion which in the initial stroke and turn the knob counter-clockwise.
In case the suspension is too soft throughout the entire stroke (bottom out suspension), then the spring is too soft or too soft compression setting.
Increase the pressure in the suspension or replace the spring with a stiffer one or increase the compression damping at high speed compresion which is in the final stroke or low speed compresion which is the initial stroke and rotate the knob clockwise.
In case when first bump in a series is taken well but harsh over later bumps, poor traction in washboard corners worse - harden, then the suspension is too suppressed - rebound too closed.
Increase the damping rebound on low speed rebound and rotate the knob counter-clockwise.
If the suspension returns too quickly to bumps and grip is poor on bumpy curves, then the damping is too fast - Rebound too opened.
Decrease the damping rebound on low speed rebound and rotate the knob clockwise.
