Pull the throttle lever off the side of the carburetor cap by hand. Slide the saved spacer ring on the saved screw. Thread the screw back into place on the side of the carburetor and tighten it securely with the screwdriver or hex wrench.

Attach a metric wrench onto the throttle cable adjuster at the carburetor cap. The cable was adjusted to work with the governor and must be readjusted for maximum throttle response. Rotate the cable adjuster counterclockwise two turns with the wrench.

Grip the section of the cable just above the carburetor between two fingers and your thumb. Twist the throttle grip at the handlebars and note the point where you feel tension on the cable. If necessary, adjust the cable again until you feel tension the instant you twist the throttle grip.
