The factory settings for the KTM 65 SX carburetor typically include a main jet size of around 80-85, a pilot jet size of 45, and the needle set in the middle position. The air screw is usually set at 1.5 turns out from fully seated. However, these settings can vary based on altitude, temperature, and individual rider preferences, so it's always best to consult the owner's manual or a professional for specific tuning guidance.
Try leaning out the air screw by turning it counter clockwise a quarter turn at a time. If the air screw has no effect, install a leaner pilot jet and return the air screw to 1 turn out. Proper air screw settings are usually between 1 and 2 1/2 turns out.

To restrict a KTM 50 SX, you can limit the throttle by adjusting the throttle stop screw, which reduces the amount the throttle can open. Additionally, you can remove or replace the exhaust pipe with a restrictor insert, and ensure the carburetor settings are adjusted for lower power output. It's essential to consult the owner's manual for specific recommendations and to maintain proper performance and safety.
