Product Information

Full details

The EBC CSK914 Clutch Spring Kit is designed for motorcycle enthusiasts and mechanics looking to eliminate clutch slip and restore factory performance. These heavy-duty springs provide 10 to 15 percent more tension than standard OE components, offering a more responsive engagement without significantly increasing lever effort. While they offer superior durability compared to stock springs, users must note that they should be replaced as a complete set rather than individually to ensure uniform clutch pack pressure.

FAQs

Can I replace just one or two springs if some look worn?

No, you must replace the springs as a complete engine set to ensure balanced pressure across the clutch pack.

Will this make my clutch lever feel too heavy?

No, the springs are only 10-15 percent stiffer than OE, which provides a noticeable improvement in bite without causing significant fatigue.

Is it necessary to replace the clutch plates at the same time?

While not strictly mandatory, it is highly recommended to install these springs whenever you install new clutch plates to ensure a fresh, consistent clutch assembly.

How do I know if my springs are 'tired'?

Symptoms include clutch slipping under acceleration, poor power delivery, or reduced lever resistance during gear changes.

Are these springs compatible with all motorcycle brands?

No, these are specific to certain models; always cross-reference your bike's make, model, and year with the MPN CSK914.

Troubleshooting

Clutch lever feels significantly harder than expected

Verify the springs are installed correctly and check for any binding in the clutch cable or actuator mechanism.

Clutch still slipping after installation

Ensure the clutch pack has adequate oil, correct free-play adjustment, and that the clutch friction plates are not beyond their wear limit.

Difficulty engaging gears

Re-check that the clutch cable is adjusted properly to allow for full disengagement when the lever is pulled.

Setup, Compatibility & Care

Installation of the CSK914 kit is best performed during a routine clutch plate replacement. To ensure success, follow these guidelines:

  1. Compatibility Check: Verify that your motorcycle model is specifically listed for the CSK914 part number before disassembly.
  2. Full Replacement: Never mix new EBC springs with old factory springs, as this will lead to uneven pressure and clutch chatter.
  3. Torque Specifications: Always consult your vehicle service manual for the correct torque settings for the pressure plate bolts.
  4. Inspection: Inspect the clutch basket for 'notching' while the cover is off, as worn baskets can interfere with spring movement.
  5. Maintenance: Periodically check your clutch cable tension or hydraulic fluid, as proper free-play is essential for the longevity of your new springs.
