Iridium Spark Plugs have the highest melting point that can withstand heat, and last longer. The manufacturing companies mention their replacement time in the instruction manuals.
How Long Do Iridium Spark Plugs Last in a Motorcycle? Iridium spark plugs in a motorcycle can last for around 52000 to 79500 miles and have a maximum lifespan of nearly 99000 to 100000 miles. They have engine uptime of about 3100 to 3900 hours, and you can improve their lifespan by moderate acceleration, cleaning, and correct installation.
They require replacement after thousands of miles because a malfunctioning plug causes engine failures and reduces fuel economy. However, their shelf life improves with adequate maintenance and cleaning.
What is the lifespan of Iridium Spark Plugs on a Motorcycle?
Iridium spark plugs have exceptional and durable metallic electrodes. The average lifespan of the classic iridium plugs is around 52000 to 79500 miles.
However, they have a maximum life expectancy of about 98000 to 99000. They can survive for 100000 to 110000 miles with correct utilization and adequate maintenance.
Moreover, they facilitate improved ignition with exceptional internal combustion of the power equipment and continuous power flow in different parts.
They have significant durability and can tolerate excessive heat levels in the power equipment. Furthermore, they have a rip of iridium, which has one of the highest melting points.
The high-performance metal makes them efficient for the high acceleration and power control mechanisms. They promote the performance of a motorcycle with their heat tolerance and better ignition properties. They are fuel-economical and improve the quick start.
According to the research, they have an engine uptime. In such circumstances, they can survive for around 3100 to 3900 hours of the uptime of the motorcycle’s power equipment.
Their time varies according to the design, size, and quality of the gas inside the system. Also, the manufacturing companies mention their estimated uptime on the manuals.
During this time, they work without internal cracking and wearing. The excessive usage of these objects leads to their frequent replacements.
However, old equipment cracks due to increased heat and affects the engine’s performance.
Also, you can follow the instructions in the manual to replace them on your bike. Their physical damages recommend instant replacement without further delay.
How often should you change Iridium Spark Plugs on a motorcycle?
You cannot leave a broken iridium spark plug inside the motor because it reduces work efficiency. In addition, due to the following reasons, they require instant replacement.
Reduction of fuel economy
They are one of the most significant additions to the latest motorcycles to improve the miles per hour. Moreover, they are compatible with high-quality gasoline and survive thousands of miles.
But, a worn-out or cracked iridium electrode reduces the mileage of the bike. Furthermore, the ignition of the motorcycle decreases from the standard operating level.
In such conditions, they affect fuel burning and reduce the efficiency of combustion activities. As a result, you can assess a drastic change in the overall fuel economy of the bike.
Moreover, the external air and dirt particles contaminate the electrode. As a result, it cannot function correctly and alters the combustion cycles.
In such conditions, they require an immediate change before their standard replacement time.
Idling of the engine
Due to a malfunctioning iridium spark plug, the bike’s engine idles without a warning sign. Also, it produces loud clicking and rattling sounds due to excessive friction in different components.
Due to massive vibrational effects, the electric wires and connectors lose from their mounting points. As a result, the electric flow changes inside the system.
In such situations, you should change them with new and compatible plugs to reduce multiple motor failures. However, excessive engine idling reduces the acceleration and overall performance of the bike.
Cylinder misfire and damages
You can clean spark plugs by removing them from the system. During these activities, you may find the accumulated oil on the top of these plugs.
However, the broken valves, malfunctioning O-rings, and degraded gaskets cause this oil leakage. In addition, the built-in high-performance gaskets cannot store the oil inside the system due to the broken cover of the valve.
As a result, the cylinders of the bike’s engine undergo several misfires and internal degrading. To resolve this problem, change the old and malfunctioning equipment.
After the replacement, you can start the electric motor and motorcycle without a significant problem.
How to make Iridium Spark Plugs last longer on a motorcycle?
Here are tips to make your iridium spark plugs last longer on your motorbike.
Slow speed levels
They can increase the standard acceleration frequencies and torque of motorcycle engines. As a result, a few riders keep their speed low for a long time.
Moreover, the repetition of such activities reduces the pattern of compression. Therefore, you should not maintain a constant low level of acceleration on different road surfaces because their internal pressure decreases multiple times.
Furthermore, maintain higher acceleration on different roads to improve their life expectancy. In such conditions, they regain power from ignition continuously.
As a result, their standard operating level changes, and you have to replace them.
Excessive contamination
You can wipe off the accumulated oil from the tip of these iridium spark plugs. They require cleaning and maintenance once every week. However, they are versatile with complicated designs.
Moreover, cleaned equipment cannot facilitate a similar performance as a new and compatible plug. This is because the electrical discharge becomes low in these plugs.
Also, the penetration of dust inside the plugs leads to corrosion over their surface. High heat levels can burn them and reduce their performance.
However, you can scrape off the dirt particles, which are highly flammable due to their metallic properties. In addition, in the combustion unit for the engine, the metallic dust causes contamination due to the mixing of fluorine and internal fluids.
It decreases the life expectancy of these high-performance spark plugs. However, wipe and clean them with a wired brush every 2 to 3 times a month.
Rub the soft brush over their top and remove the contaminants. Never use abrasive equipment to clean these delicate plugs.
Incorrect adjustment
Spark plugs require a correct installation in their mounting spots in the motorcycle. Sometimes, they undergo multiple damages and internal wear due to incorrect placement inside the engine.
In such circumstances, they do not provide enough spark for ignition. As a result, you cannot start the engine, and acceleration reduces.
Install them over the upper side of the engine. Follow the rubber boots and connect black electric wires. Remove the covers and fairings for their correct adjustment.
