The Kawasaki coil pack, also called the ignition coil, is a crucial component of the ignition system. It converts the low voltage energy from the battery into high voltage energy to produce sparks in the engine's combustion chambers. Without a functional ignition coil, the engine will not start or may misfire, leading to performance and emission issues. Coil packs are used in most modern internal combustion engines, including Kawasaki's electric and petrol-powered engines. They improve engine performance while reducing emissions.
The Kawasaki coil pack comes in different types, depending on the engine model and ignition system. The first type is the Kawasaki single ignition coil, also called the ignition coil. This coil gets its name from its single, solitary configuration. Its primary purpose is to supply spark to a single spark plug, making it an ideal choice for smaller, less powerful engines. In most cases, this type of ignition coil can be found in engines with a 2-stroke or 2-cylinder configuration. It can be used in some 4-stroke and 4-cylinder engines. However, if the engine is larger, it may require more than one ignition coil to provide sufficient spark power to all the spark plugs.
The second type is the Kawasaki dual ignition coil. As the name suggests, this coil is designed with a dual configuration, making it suitable for larger and more powerful engines. Like the single ignition coil, the dual coil also generates electrical energy and sends it to the spark plugs. However, it does so for two spark plugs simultaneously. This makes it a suitable ignition coil for 4-stroke, 4-cylinder, or 2-stroke, 2-cylinder engines. The dual ignition coil is more efficient and reliable than its single counterpart. It also enhances engine performance, making it a popular choice for most modern Kawasaki engines.
The third type is the Kawasaki coil-on-plug (COP) ignition system. The COP ignition system is a modern and advanced ignition technology that many modern Kawasaki engines use. Instead of using a single or dual ignition coil to supply all the spark plugs, the coil-on-plug system uses a separate ignition coil for each spark plug. This means that if an engine has 4 spark plugs, it will have 4 individual ignition coils, one on top of each spark plug. This configuration ensures that every spark plug receives a consistent and powerful spark, improving combustion efficiency and engine performance. The COP ignition system also reduces emissions by ensuring complete fuel burn. This advanced ignition system enhances engine performance, fuel efficiency, and low emissions. For this reason, many high-performance engines use the coil-on-plug ignition system.
The specifications of the Kawasaki coil pack may differ depending on the make and model of the bike. Generally, the coil has two sets of wire windings around an iron core. One set, called the primary winding, has a small number of turns and is connected to the bike's battery voltage. The secondary winding has many turns of wire and is connected to the spark plug. The two windings are linked by the iron core.
The Kawasaki coil pack receives a signal from the bike's ECU. This signal indicates when the engine is cranking or running. Once it receives the signal, the coil pack starts working. It draws power from the bike's battery and generates a voltage. This voltage is enough to ignite the air-fuel mixture in the combustion chamber. The ignition voltage generated by the coil pack can reach 30,000 volts or more.
The coil pack works by creating a magnetic field between the primary and secondary windings. When the bike runs, the ECU sends a signal to the coil pack. This signal tells the coil pack to start working and generates voltage. The voltage generated by the coil is transferred to the spark plug through the ignition wire. When the voltage reaches the spark plug, it creates a spark that ignites the air-fuel mixture in the engine's combustion chamber.
Below are some general maintenance tips for the Kawasaki coil pack:
Selecting the right Kawasaki ignition coil is crucial for maintaining optimal engine performance. Here are some key factors to consider when choosing coil packs:
Compatibility
Coil packs must be compatible with the make, model, and year of the vehicle. This ensures the coil pack fits the engine and matches its specifications.
Engine Type
Consider the kind of engine the coil pack will be used. For instance, larger and more powerful coil packs are generally needed for high-performance engines.
Brand and Quality
It is advisable to choose coil packs from reputable brands. Quality coil packs may have a higher initial cost but can be more reliable and durable in the long run.
Budget
Kawasaki ignition coil packs are available in various price ranges. It is advisable to set a budget and shop around to find a coil pack that fits the budget and needs.
Warranty and Support
Some manufacturers offer warranties and customer support. This can be useful in case of any issues or questions regarding the installation or use of the coil pack.
Reviews and Recommendations
Reading online reviews or asking for recommendations from friends or mechanics can help find a coil pack that is reliable and meets the needs.
Replacing a Kawasaki ignition coil on a small engine, like a lawnmower or leaf blower, can be done with basic tools. Before starting, make sure to get the new coil pack that matches the engine's model number. Here's how to do it:
Step 1: Safety First
Turn off the engine and unplug the spark plug wire. This prevents accidental starting or shock while working.
Step 2: Gather Tools
Find a screwdriver, socket set, and pliers. These will help take the old coil out and put the new one in.
Step 3: Remove Covers
Use screws or bolts to take off any plastic or metal covers that hide the ignition coil. The coil is usually under these.
Step 4: Unplug Wires
Carefully note where they go, then unplug the electrical wires from the old coil. Also, remove any ground wire or screw holding the coil down.
Step 5: Take Out Old Coil
Use a socket or wrench to unscrew the ignition coil from the engine. It should come right out.
Step 6: Install New Coil
Put the new coil pack into the engine using the same screws. Make sure it sits in the same place as the old one.
Step 7: Connect Wires
Plug the same electrical wires and ground wire into the new coil. Refer to the pictures taken earlier to connect them correctly.
Step 8: Replace Covers
Screw or bolt down any plastic or metal covers that were removed. This keeps dirt out of the engine.
Step 9: Test It Out
Plug the spark plug wire back onto the coil. Then, plug the wire into the spark plug. Turn on the engine. It should run smoothly if the coil was installed correctly.
Check the owner's manual for specific instructions and coil pack locations. But this general process should work on most small engines. Call a repair shop if it does not run after replacing the coil.
Q. Do I have to use original equipment (OEM) coil packs on my Kawasaki, or are aftermarket brands okay?
A. OEM coil packs are not required. Many Kawasaki run just fine on aftermarket coil packs. Just be sure the coil packs are made to fit the particular model and year of the Kawasaki.
Q. How long should a coil pack last on a Kawasaki?
A. Coil packs on most Kawasaki bikes and engines should last 50,000 to 100,000 miles or more. Coils that are well cared for and used gently can last a really long time. But wear and tear from heavy use, bad maintenance, or other problems can shorten their lifespan.
Q. What are the benefits of upgrading to a high-performance ignition coil?
A. High-performance ignition coils can give extra power and better performance. They provide a stronger spark to the engine. This can result in smoother running, more horsepower, and better fuel efficiency. Coils from well-known brands are used by many racers and others who want upgrades.
Q. What is the warranty like on coil packs?
A. Most come with a 6-month to 1-year warranty. Some have a limited lifetime warranty. Warranty length and terms can vary quite a bit depending on the brand, seller, and other factors.
