Frequently Asked Questions
How many performance clutch springs are included?
Six Japanese-made performance clutch springs are included, enough to replace the complete spring set on one compatible CB550, CB650 or CB750 clutch.
What can performance clutch springs improve?
Their increased clamping force can help a serviceable clutch hold under higher load. They will not repair worn friction plates, warped steel plates, a notched basket or incorrect adjustment.
How should performance clutch springs be installed?
Install all six matched springs together, tighten the pressure-plate bolts gradually and evenly to the Honda specification and reset clutch free play after assembly.
