This replacement clutch fork return spring is one of many components included in your Z1 CSC Elimination Kit, now available for purchase as a track-day spare or single component replacement. The spring originally included in your CSC Elimination kit is made to tighter dimensional and load tolerances than typical springs, however overtime they will fatigue as they're repeatedly stretched and heat cycled. This often results in a loss of spring tension, or in some cases a simple broken spring.
