Setup and Installation
Warning: Clutch installation requires mechanical knowledge and specialized tools. If you are not confident in your ability to perform this installation, seek assistance from a qualified motorcycle mechanic.
Before You Begin:
- Ensure the motorcycle is on a stable stand and the engine is cool.
- Gather all necessary tools, including a torque wrench, sockets, screwdrivers, and a drain pan.
- Have fresh engine oil and a new clutch cover gasket available.
- Refer to your motorcycle's service manual for specific torque specifications and detailed disassembly/assembly procedures.
Installation Steps:
- Drain Engine Oil: Place a drain pan beneath the engine and remove the oil drain plug to completely drain the engine oil.
- Remove Clutch Cover: Carefully remove the bolts securing the clutch cover. Gently tap the cover to loosen it, then remove it. Be prepared for residual oil to drain.
- Remove Pressure Plate and Springs: Loosen and remove the clutch spring bolts in a crisscross pattern to relieve tension evenly. Remove the pressure plate and clutch springs.
- Remove Old Clutch Plates: Carefully remove the old friction and steel plates from the clutch basket. Note the order of removal, as this is crucial for reassembly.
- Inspect Components: Inspect the clutch basket, inner hub, and pressure plate for any signs of wear, grooving, or damage. Replace any damaged components.
- Prepare New Plates: Submerge the new Wiseco friction plates in fresh engine oil for at least 30 minutes prior to installation. This ensures proper lubrication and prevents premature wear.
- Install New Clutch Plates: Install the new friction and steel plates into the clutch basket in the correct sequence, alternating between friction and steel plates. Ensure the first and last plates are friction plates, unless your motorcycle's service manual specifies otherwise.
- Install Pressure Plate and Springs: Place the pressure plate back onto the clutch assembly. Install the new Wiseco clutch springs and spring bolts.
- Torque Clutch Springs: Tighten the clutch spring bolts in a crisscross pattern to the torque specifications provided in your motorcycle's service manual.
- Install Clutch Cover: Clean the clutch cover and engine case mating surfaces. Install a new clutch cover gasket. Carefully place the clutch cover back onto the engine case and tighten the bolts to the specified torque.
- Refill Engine Oil: Refill the engine with the recommended amount and type of fresh engine oil.
- Adjust Clutch Cable: Adjust the clutch cable free play according to your motorcycle's service manual.
Operating Considerations
After installation, proper break-in and operation are crucial for optimal clutch performance and longevity.
- Break-in Period: Avoid aggressive clutch engagement, excessive slipping, or hard acceleration for the first 50-100 miles (80-160 km) after installation. This allows the new clutch plates to seat properly.
- Clutch Feel: The Wiseco clutch springs are 8-10% stiffer than stock, which may result in a slightly firmer clutch lever feel. This increased stiffness ensures positive clutch lockup.
- Regular Checks: Periodically check clutch lever free play and adjust as necessary to maintain proper operation.
Maintenance
Regular maintenance helps extend the life of your clutch and ensures consistent performance.
- Oil Changes: Adhere to your motorcycle manufacturer's recommended oil change intervals. Using fresh, high-quality engine oil is vital for clutch health.
- Clutch Adjustment: Regularly check and adjust clutch cable free play. Incorrect free play can lead to premature wear or clutch slip.
- Inspection: During routine engine maintenance or oil changes, consider inspecting the clutch components for signs of wear, such as discolored plates, grooved baskets, or weakened springs.
