What does a primary clutch spring do?

The primary clutch spring works with the clutch weights to control when your clutch engages and how high your engine revs at wide-open throttle. Changing the spring allows you to adjust these engagement points.

What is the significance of the 5% tolerance?

A strict 5% tolerance means the spring's performance will be very consistent and reliable. This low tolerance is important for predictable clutch operation, especially when fine-tuning engagement.

How do the load specifications relate to performance?

The load specifications (kg at different inch measurements) indicate how much force the spring exerts at various compression points. These numbers help determine the engagement speed of the clutch and the engine's maximum RPM.
