If the scooter motor is to work correctly and efficiently, the spark between the electrodes must be ignited with absolute reliability. A misfiring, for example, can result in an entire cylinder filling of the air-fuel mixture reaching the exhaust system unburned and only burning there inside the catalytic converter. Just a few misfires can be enough to damage the catalytic converter or even render it completely unusable. A scooter engine, usually with a small displacement and high speeds, places high demands on a spark plug. The spark plug often experiences many cold starts and high speeds, which means that regular replacement is mandatory for trouble-free operation. Choosing the right spark plug is essential for trouble-free operation! We recommend everyone to stick to the manufacturer's.
