Do I need to install the lever cam with aftermarket levers?

If your clutch lever is properly adjusted and the bike does not creep with the lever fully pulled in, then the Brock's Lever Cam is not required.

⚠️ IMPORTANT: NEVER RIDE WITH CLUTCH CREEP

Clutch creep is a sign of a serious issue and must be addressed before riding or racing.

🔥 Severe Clutch Creep (Dangerous):

The bike tries to lunge forward or move when put in gear—even with the clutch lever fully pulled. This could be due to:

• Improper cable or hydraulic adjustment

• Clutch slave cylinder issues

• Cracked sprocket cover (Gen 1 Hayabusa)

• Incorrect stack height

• Loose or damaged clutch hub nut

• Warped clutch steels or damaged plates

• Misaligned or incorrect clutch pressure plate installation

Do not operate the bike. Consult your service manual or a professional mechanic.

Mild Clutch Creep (During Launches):

The bike starts to pull through the staging beams on a drag strip, especially when attempting a hard launch. This should also be corrected before making a pass, as even holding the bike back for one launch can overheat and ruin the clutch.

Common causes include:

• Fresh fiber plates swelling after oiling (dry hop + recheck adjustment)

• Warped steel plate in the clutch pack

• Incorrect stack height (follow your manual’s minimum thickness specs)

• Clutch spring bind (especially when using non-Brock’s springs or improper setups)

• Using the Clutch Cushion without our Lever Cam

• Old/worn clutch lines—replace with braided stainless lines

• Notched inner hub—file smooth or replace

• Worn outer hub or backing plate—inspect and replace as needed

Final Note:

If you're using our Clutch Cushion Kit, we recommend using the Brock’s Lever Cam—especially in drag race conditions—for maximum compatibility and performance.
