The valve clearance for a Suzuki LT 300, specifically for the 1990-1991 model, is typically set at 0.08 mm (0.003 inches) for both the intake and exhaust valves. It's important to check this specification in the owner's manual or service manual for your specific model year, as tolerances may vary slightly. Regular maintenance of valve clearance can help ensure optimal engine performance.
The valves are adjusted by loosening a 10 mm jam nut and checking the clearance with a feeler gauge. A certain procedure must be followed. Just Google "denlors valve adjustment article" for detailed "how to" instructions for most 4cyl Honda engines.
