Spark plug motorcycle BR9ECM

As the main source of energy in any petrol engine, a spark plug performs an essential function: it is responsible for igniting the air-fuel mixture in the combustion chamber of petrol engines. This combustion process creates energy and makes your vehicle run.
To ensure that the combustion process works smoothly, the spark from the spark plug must occur just before the piston reaches its highest point and compression is at its maximum, which is why it is important to keep the spark plug in good condition.
Check that the spark plug is the one recommended by the manufacturer
