1. Locate the rear shock. It is positioned in the center of the swingarm, just below the seat.
2. Find the adjustment knob. It is located on the top of the shock, and has a flathead screwdriver slot in the center.
3. Use a flathead screwdriver to turn the adjustment knob. Turning the knob clockwise will make the shock stiffer, while turning it counterclockwise will make it softer.
4. Test the adjustment. Sit on the quad and bounce up and down on the seat. The shock should compress and rebound smoothly, without bottoming out or feeling too stiff.
5. Repeat steps 3 and 4 until you find the desired adjustment.
Note: The rear shock adjustment on the 350 Yamaha Warrior is only for preload. If you need to adjust the rebound or compression damping, you will need to install an aftermarket shock.
