Symptoms of a failing motorcycle hs spark plug:

What are the symptoms of a failing HS motorcycle spark plug?

Many people assume that when their motorcycle has trouble starting, there is something wrong with the battery. While it may be the case, it is not the only possibility. Old or defective hs spark plugs may be the cause! After all, these little hs candles have a big job to do. Here is a list of symptoms you need to take into consideration to find out if your motorcycle's spark plug is faulty.

Motorcycle spark plugs - General information 

There are a whole bunch of motorcycle spark plugs on the market that meet specific needs. So, before you get started, we advise you to take a look at our complete guide on the subject.

Faulty hs motorcycle spark plug due to check engine light problem

Worn spark plugs or spark plug wires can cause the check engine light to come on. According to technicians, in today's motorcycles, if an HS spark plug begins to fail, the most obvious event is the check engine light coming on or flashing. This can cause misfires in the engine and the check engine light to come on. A flashing engine light can mean potentially catastrophic misfire occurring, technicians say.

In general, it is best to replace hs spark plugs as part of preventative maintenance based on the manufacturer's specifications. This can save you costly repairs, as driving with faulty hs motorcycle spark plugs can put excessive strain on your motorcycle's catalytic converter (the engine's exhaust filter).

Slow acceleration caused by a failing hs motorcycle spark plug

The most common cause of poor acceleration in most motorcycles is a problem with the hs spark plugs. Today's modern engines are equipped with several sensors that tell the ignition system when to send electrical pulses to ignite the hs spark plug, so the problem may be with a faulty sensor. However, sometimes the problem is as simple as a worn hs spark plug. A hs motorcycle spark plug is made of materials that work together to produce a spark hot enough to ignite the air-fuel mixture. When these materials wear out, the efficiency of the spark plug is reduced, which can significantly reduce vehicle acceleration.

If you notice that your motorcycle is running slowly or not accelerating as fast as it used to be, it can be attributed to a faulty hs spark plug that needs to be replaced. However, you should contact a mechanic to inspect this issue as it could be caused by multiple other factors including faulty fuel filters, a dirty or clogged fuel injector, or issues with the oxygen sensors.

Faulty hs motorcycle spark plug due to poor fuel economy

A perfectly functioning hs spark plug helps to burn fuel efficiently in the combustion cycle. When this happens, your motorcycle can achieve above average fuel savings. When the spark plug is not performing optimally, it is often because the gap between the spark plug electrodes is either too close or too far. In fact, many mechanics take hs spark plugs apart, examine them, and adjust the gap to factory settings instead of replacing the spark plug entirely. If your motorcycle's fuel consumption increases, it could very well be due to a worn hs spark plug.

The engine has misfires

If the engine is misfiring, it is usually due to a problem with the hs spark plugs. On modern motorcycles, this is usually due to a sensor malfunction. However, it can also be caused by a spark plug wire or the end of the spark plug connecting to the damaged wire. A misfire may be noticed by intermittent tripping or spitting noises from the engine. If the engine continues to misfire, exhaust gas emissions increase, engine power decreases, and fuel consumption decreases.

Faulty hs motorcycle spark plug due to startling engine

You may notice that the engine hesitates when accelerating. In this case, the motor does not respond correctly to the driver. He can suddenly increase his power and then slow down. The engine sucks in more air than it should in its combustion process, resulting in a delay in the delivery of power. The combination of hesitation and revving can indicate hs motorcycle spark plug problem.

Difficult to start

If you are having trouble starting your motorcycle, it may be a sign that your hs spark plugs are worn out. As we saw above, the engine's ignition system is made up of several individual components that must work together in order to function properly. At the first sign of a problem starting your motorcycle, truck, or SUV, it is a good idea to contact a certified mechanic to investigate the cause.

Whatever the problem, you might need new hs moto spark plugs when yours wears out. By being proactive on maintenance and hs motorcycle spark plug cleaning, you can extend the life of your engine by several hundred thousand kilometers.
