Instructions
Locate the throttle's hand control on the ATV's handlebars. This is on the right-side handlebar.
Loosen the jam nut on the rear of the throttle with a wrench.
Turn the screw clockwise to increase the speed and counterclockwise to decrease the speed.
Tighten the jam nut to lock in the adjusted speed. Take the ATV for a test drive to assure the proper speed has been set.
