Let's see the useful information on how to disassemble and replace the spark plug of the Kymco Agility 125 scooter engine. First, we place the scooter on the central stand and begin removing the plastic cover located next to the footrest, thus accessing the engine head; then we disconnect the spark plug's electrical connector, and using a socket wrench with an extension, we unscrew and remove it, as shown in the video. At this point, we install the new spark plug, of the correct type and with the same thread pitch, screwing it in by hand and then tightening it with a wrench; we reconnect the spark plug connector and reassemble the plastic cover.
