To set the timing on a 1985 ATC 250 SX, first, remove the left side cover to access the ignition system. Use a timing light and align the timing mark on the flywheel with the designated mark on the stator at the specified RPM (usually around 1,500 RPM). Adjust the stator by loosening the screws and rotating it until the marks align, then tighten the screws securely. Reassemble the cover and test the engine to ensure proper timing.
For a 250 SX KTM recommends Motorex Top Speed 4T 15W50 (.7 L). For a 250 SX-F KTM recommends Motorex Power Synt 4T 10W50 (1.1 L).

On a Honda 250 SX, the increase and decrease adjustments on the right side of the motor typically refer to the throttle and idle adjustments. The throttle adjustment controls the amount of airflow to the engine, affecting acceleration, while the idle adjustment sets the engine's idle speed when not in gear. Properly tuning these adjustments ensures optimal performance and responsiveness of the motorcycle. Always consult the owner’s manual for specific settings and recommendations.
