Clutch adjustment washers
Your Cobra comes stock with flat washer(s) at the bottom of the spring washer
stack. Cobra offers several thicknesses of thin adjustment washers that allow
clutch engagement tuning. Increasing the flat washer(s) thickness increases the
engine speed for clutch engagement thus increasing the abruptness of clutch
engagement (harder hit). Conversely, decreasing the flat washer(s) thickness
decreases the engine speed for clutch engagement thus decreasing the
abruptness of clutch engagement (softer hit).
