The spark plug gap for a 1974 Yamaha DT125 is typically set at 0.6 to 0.7 mm (0.024 to 0.028 inches). It's essential to check the gap before installation to ensure optimal engine performance and ignition efficiency. Properly gapping the spark plug can help prevent misfires and improve fuel combustion. Always refer to the owner's manual for the most accurate specifications.
