Installation Guide

⚠️ Important: Use WD-40 or a similar cable lubricant to lubricate the OEM clutch cable before installation.

Step 1: Remove OEM Clutch Cable

• Disconnect the clutch cable from the lever end (Fig. A).
• Loosen the lock nuts at the engine yoke and remove the cable head from the engine (Fig. B).

Step 2: Install Easy Clutch Pro Plus

• Insert the 2B cable into the engine-side mount, reversing the removal steps (Fig. B).
• Ensure maximum slack by loosening the lock nuts.
• Route the cable along a smooth, unobstructed path.
• Insert the 2A cable head into the clutch lever (Fig. A).

Step 3: Adjust Clutch Release Point

• Target: Set clutch release to occur at approximately 50% of lever travel.

Adjustment Instructions:

• If the release point is below 40%, thread out the adjuster on either side of the housing (Fig. C).
• If the release point is above 60%, thread in the adjuster (Fig-E).
• Further fine-tuning can be done at the engine-side adjuster (Fig-D or Fig-F):
  • (a): Brings the release point closer to the grip.
  • (b): Moves the release point farther from the grip.

Usage & Safety Disclaimer

Too much free play may prevent the clutch from fully disengaging, causing:

• Difficulty in shifting gears
• Trouble selecting neutral
• Premature clutch release (below 40%)

Too little free play may result in the clutch not fully engaging, leading to:

• Clutch slippage
• Loss of power
• Accelerated clutch wear

Always check and fine-tune free play to stay within the recommended 40–60% release range.
