Frequently Asked Questions

Q: What is the primary function of the NA107 Purple Spring in a racing clutch?

A: The NA107 Purple Spring acts as a tensioner that determines your clutch engagement RPM. By setting the stall at 3400 RPM for Star clutches or 2400 RPM for MiniCup clutches, it allows the engine to reach a higher power band before the clutch fully engages, resulting in more explosive acceleration off the corners.

Q: How do I know if the Purple Spring is the right choice for my kart?

A: This spring is ideal for drivers looking for "rev-happy" tuning. If you feel your kart is sluggish coming out of tight turns, the higher stall speed of the Purple spring helps keep your engine in its peak power range, provided your engine setup supports that engagement threshold.

Q: Is the NA107 spring compatible with both Star and MiniCup clutches?

A: Yes, this spring is versatile. It provides a 3400 RPM stall when used in Nor-Am Star clutches and a 2400 RPM stall when used in MiniCup clutch systems.

Q: Can I mix and match different colored springs in my clutch?

A: It is highly recommended to use a consistent set of springs across the clutch assembly to ensure even engagement and prevent premature wear or vibration. Always replace springs as a complete set to maintain balanced performance.

Q: How often should I replace my clutch springs?

A: Clutch springs are subject to heat cycles and mechanical fatigue. If you notice your engagement RPM dropping or inconsistent acceleration, it is time to inspect your springs for signs of fatigue or "fade." Replacing them regularly ensures your kart maintains its competitive edge.
