The driven clutch, helix/moveable assembly has
several different spring locations which affect clutch
shifting and RPMs. The greatest amount of spring
tension will raise engine RPMs during clutch upshift
and allow quicker backshift or downshift when pulling
or negotiating a hill, for example. The least amount of
tension will create a slower downshift and a harder
upshift.
