Using this Wild Kart seat mounting tool is easy. First, hang it on the bottom of your kart off the main frame rails. Then, adjust the width to match your kart's frame rail size. You can set it anywhere between 21' and 26 3/4'. After that, use the adjustable shims to ensure a perfect fit. When you're satisfied with the setup, you can start mounting the seat. As for maintenance, keep it clean and dry to prevent rust. If you notice any parts getting loose, tighten them up. Also, store it in a safe place when not in use to avoid damage.
