To adjust the idle speed on a Yamaha TTR 230, locate the idle adjustment screw, which is typically found on the right side of the carburetor. Start the engine and let it warm up, then turn the idle adjustment screw clockwise to increase the idle speed or counterclockwise to decrease it. Make small adjustments and listen for the desired idle speed, usually between 1,200 to 1,500 RPM. After adjustment, ensure the engine runs smoothly and consistently at idle.
