1. Gather the necessary tools and materials.
• Feeler gauge
• Flathead screwdriver
• 12mm wrench
• Ratchet
• Spark plug wrench
2. Prepare your motorcycle.
• Turn off the engine and let it cool down completely.
• Disconnect the negative terminal on your battery.
• Remove the seat.
a. Remove the two Phillips-head screws that secure the seat to the frame.
b. Lift the rear of the seat up and off of the motorcycle.
3. Remove the valve cover.
• Use a 12mm wrench to loosen the four bolts that secure the valve cover to the cylinder head.
• Remove the valve cover.
4. Inspect the valves.
• Check the condition of the valves and valve seats. Look for any signs of wear, damage, or carbon buildup.
• If there is any carbon buildup, carefully clean it away with a flathead screwdriver.
5. Adjust the valves.
• Use a feeler gauge to check the clearance between the valve stem and camshaft. The clearance should be 0.004 - 0.006 inches (0.10 - 0.15 mm) for the intake valves and 0.006 - 0.008 inches (0.15 - 0.20 mm) for the exhaust valves.
• If the clearance is incorrect, use a flathead screwdriver to turn the adjuster screw on the valve stem. Turning the screw clockwise will decrease the clearance, while turning it counterclockwise will increase the clearance.
• Repeat this process for all of the valves.
6. Reinstall the valve cover.
• Place the valve cover over the cylinder head.
• Replace the four bolts that secure the valve cover to the cylinder head.
• Tighten the bolts in a crisscross pattern.
7. Reconnect the negative terminal on your battery.
8. Replace the seat.
a. Place the seat on the motorcycle.
b. Replace the two Phillips-head screws that secure the seat to the frame.
9. Test the motorcycle.
• Start the motorcycle and let it run for a few minutes.
• Listen for any unusual noises.
• If you hear any unusual noises, stop the motorcycle and investigate the cause.
