To replace the spark plug on the Vespa GTS 125, lift the seat of the scooter to access the under-seat compartment. Once you have access to these components, locate the wire connected to the spark plug on the front right side of the under-seat compartment: by disconnecting this wire, you can use the appropriate socket wrench to remove the old spark plug from its housing. Then, insert a new spark plug, connecting it to the appropriate power wire and lowering the seat to close the under-seat compartment.
