Today's instructions will show you how to remove and replace the spark plug of the engine of the Gilera Runner 50, as well as the 125. First, place the scooter on the centre stand and start unscrewing the screws of the right side plastic fairing to remove it; then disconnect the electrical connector and use a socket wrench with an extension to unscrew and remove the spark plug, as shown in the video. At this point, install the new spark plug, ensuring it is the correct type and has the same thread pitch, hand-tightening it before gently tightening with the wrench; then reconnect the connector!
