The valve clearance for a 1981 Yamaha XS400 is typically set at 0.10 mm (0.004 inches) for the intake valves and 0.15 mm (0.006 inches) for the exhaust valves. It's important to check and adjust the valve clearance regularly to ensure optimal engine performance and longevity. Always refer to the service manual for specific procedures and specifications.
