Motorcycle engines are compact and work in harsher conditions than automobiles, mostly. That is why, and NGK, Global Spark Plug Manufacturer, recommends inspecting the component applied to motorcycles every 6 months or when it reaches 3 thousand kilometers driven. The action minimizes the risk of breakdowns, malfunctions, difficulties in starting and increased fuel consumption and pollutant emissions above average. Excessive spark plug wear can also compromise the entire ignition system.
As explained by NGK's Technical Assistance consultant, Hiromori Mori, Automobiles have multiple cylinders, allowing the driver to go to a safe location in case of emergency. Low-displacement engines are single-cylinder, increasing the risk of an ignition failure. "Excessively worn spark plug can make it totally impossible to start the engine in these cases", alert the expert. Although it varies according to the characteristics of each model, Motorcycle manufacturers recommend, via the owner's manual, the replacement of the part every 12 thousand kilometers.
Furthermore, The bi-fuel system was also developed for motorcycles and, just like in cars, brings the concern with the use at low temperatures, mainly because it does not have a cold start system. That is why, The company reinforces the need for spark plugs in good condition.
Another indication from the technician is not to force the ignition, if the rider has difficulty starting. "As the capacity of motorcycle batteries is usually smaller, insistence on departure can quickly exhaust it. Another possible problem is the soaking of the candle with fuel. It is necessary to wait until the fuel evaporates completely", Hiromori informs.
Maintenance
NGK recommends that spark plugs be inspected by your trusted mechanic, that it has better conditions to assess wear, and will be able to check the burning condition of the fuel, in addition to identifying possible engine failures. "The specialized workshops have the necessary equipment for changing and applying the specific tightening torque for the spark plugs. Excess torque or lack of it can damage components", Hiromori explains.
When replacing spark plugs, it is necessary to take into account the brand, The model, Engine capacity and the year of the vehicle. A specific component is recommended for each model. The use of inappropriate parts can compromise the operation of the engine, in addition to damaging the ignition system.
