Step 1: Gather Required Tools and Parts
Before starting the adjustment, ensure you have all necessary tools and parts:
- Feeler Gauges: Available at local auto parts stores like AutoZone.
- Suction Cup: A shower shampoo bottle holder can be used.
- Micrometer: For precise measurements. Purchase here.
- Shim Kit (7.48mm): Obtain a shim kit from here.
- Gaskets and O-rings:

Step 2: Prepare the Motorcycle
- Park the motorcycle on a level surface and make sure the engine is cool.
- Disconnect the battery to ensure safety during the process.
- Remove the seat and any fairings that obstruct access to the valve cover.
Step 3: Access the Valve Cover
- Remove the necessary components to reach the valve cover:
- Unscrew and detach any parts that block access (like air intake or electrical connectors).
- Carefully lift the valve cover off, ensuring not to damage any gaskets.
Step 4: Measure Valve Clearances
- Use the feeler gauges to check the valve clearances:
- Intake clearance should be between 0.15mm and 0.24mm.
- Exhaust clearance should be between 0.22mm and 0.31mm.
- Insert the feeler gauge between the valve and rocker arm, ensuring a snug fit but without excessive resistance.
Step 5: Adjust Valve Clearances
- If adjustments are needed:
- Remove shims from the affected valves.
- Replace with the appropriate thickness shim to achieve the desired clearance.
- Recheck the clearance after each adjustment to ensure accuracy.
Step 6: Reassemble the Motorcycle
- Once all clearances are set, reapply the valve cover with a new gasket.
- Reattach any components removed during the disassembly process:
- Ensure all screws and bolts are tightened to manufacturer specifications.
- Reconnect the battery and any electrical connections.
