How do you change the spark pug in a 94 fourtrax?

To change the spark plug in a 1994 Honda FourTrax, first ensure the engine is cool and disconnect the negative battery terminal for safety. Remove the spark plug cap and use a spark plug socket and ratchet to unscrew the old spark plug. Install the new spark plug by hand to avoid cross-threading, then tighten it with the ratchet. Finally, reattach the spark plug cap and reconnect the battery.
