Do you have an old motorcycle that just won't start? Don't worry, we've got you covered. Here is the best and most detailed guide for you. This guide will show you exactly how to jump start your dead motorcycle, ensuring you're back on the road in no time.
Why Your Motorcycle Could Not Start Up
There are several reasons why your motorcycle might not start up, even if you suspect a dead battery.
Faulty Starter Motor
The starter motor is responsible for cranking the engine. If it fails, your motorcycle won't start. Signs of a bad starter include a clicking noise when you press the start button.
Blown Fuses
A blown fuse can interrupt the electrical circuit, preventing your bike from starting. Check the fuse box and replace any blown fuses with the correct rating.
Clogged Fuel Lines
If your motorcycle has been sitting for a while, fuel lines might get clogged with debris or old fuel. This can prevent fuel from reaching the engine. Clean the fuel lines and replace the fuel filter if necessary.
Ignition Switch Problems
The ignition switch can wear out over time, leading to starting issues. If the switch is faulty, it might not send the correct signal to start the engine.
Faulty Spark Plugs
Spark plugs ignite the fuel-air mixture in the engine. If they are worn out or dirty, they won't produce a spark, and the engine won't start. Inspect and replace the spark plugs if needed.
Kill Switch Engaged
It might sound simple, but always check that the kill switch is in the "run" position. If it's engaged, the engine won't start no matter how much you try.
Battery Connections
Loose or corroded battery terminals can prevent the battery from delivering power to the motorcycle. Ensure the connections are tight and clean.

What is Jump Starting a Motorcycle
It's a process where you use an external power source to get your bike's engine running. Think of it as giving your motorcycle a jolt of electricity, much like a defibrillator does for a human heart. The most common scenario involves connecting your bike to another vehicle's battery, providing the necessary energy to start the engine.
Why would you need to jump start your motorcycle? Well, batteries can die for numerous reasons, such as leaving the lights on, not riding your bike for an extended period, or simply due to the battery's age. When this happens, you might find yourself stranded with a dead motorcycle. But don't worry, jump-starting is a straightforward process if you follow the right steps.
Rule Out Other Issues Before Jump Starting
Before you jump into the jump-starting process, it's crucial to ensure that a dead battery is indeed the issue. Sometimes, what seems like a dead battery could be something else entirely, like a faulty starter, a blown fuse, or even a clogged fuel line. Ruling out these potential problems can save you a lot of time and effort.
Start by checking the basic things: make sure the ignition is on, the kill switch is set to "run," and the fuel valve (if your bike has one) is open. Listen for any unusual sounds when you try to start the bike, as these can be clues to other issues. If everything else seems fine, it's time to test the battery.
How to Jump Start a Motorcycle with a Dead Battery
First things first, you need to test the motorcycle battery before jump-starting it. Use a battery tester like the BST600 to check the battery's health.
Turn off the motorcycle and ensure it's in neutral.
Connect the BST600 battery tester to the battery terminals. The red clip goes to the positive terminal, and the black clip goes to the negative terminal.
Follow the instructions on the BST600 screen to perform the test. The tester will give you a reading of the battery's voltage and health status. If the battery is indeed dead or too weak, you can proceed with jump-starting.
Once you're sure the battery needs a jump, you'll need jumper cables and an external power source, like another motorcycle or a car.
Here's how to jump start your motorcycle:
Park the donor vehicle close to your motorcycle without the two touching. Turn off both vehicles.
Connect the positive (red) jumper cable to the positive terminal of the dead battery. Attach the other end of the positive cable to the positive terminal of the donor battery.
Connect the negative (black) jumper cable to the negative terminal of the donor battery. Attach the other end of the negative cable to an unpainted metal part of your motorcycle's frame.
Start the donor vehicle and let it run for a few minutes. This will charge your motorcycle's battery.
Attempt to start your motorcycle. If it doesn't start right away, wait a few more minutes and try again.
Once your motorcycle starts, carefully disconnect the jumper cables in reverse order. Remove the negative cable from your motorcycle first, then the negative from the donor vehicle, followed by the positive cables.
Is it OK to Jump Start a Motorcycle from a Car
The answer is yes, but with caution. While the concept is similar, car batteries are significantly more powerful than motorcycle batteries. Therefore, you need to be extra careful to avoid any potential damage.
Ensure both vehicles are turned off and in park or neutral.
Position the car and motorcycle close enough for the jumper cables to reach, but do not let them touch.
Connect the positive (red) jumper cable to the positive terminal of the motorcycle battery. This terminal is usually marked with a "+" sign.
Attach the other end of the positive cable to the positive terminal of the car battery.
Connect the negative (black) jumper cable to the negative terminal of the car battery.
Attach the other end of the negative cable to an unpainted metal part of your motorcycle's frame, away from the battery and fuel system. This serves as the ground connection.
Start the car and let it run for a few minutes. This allows the car battery to transfer some charge to the motorcycle battery.
Try to start your motorcycle. If it doesn’t start immediately, wait a few more minutes and try again.
Once the motorcycle starts, carefully disconnect the jumper cables in reverse order:
Allow your motorcycle to run for a while to ensure the battery gets enough charge.
Here are some additional tips to keep in mind:
Use heavy-duty jumper cables. Motorcycle batteries are smaller, and using thin cables might not provide enough current to start the engine.
Be mindful of the battery types. If your motorcycle has a lithium battery, using a car with a lead-acid battery could potentially cause issues. Always check compatibility.
Avoid over-cranking. If your motorcycle doesn't start within a few tries, give it a break. Over-cranking can overheat the starter motor and cause further damage.
Conclusion
Jump-starting a motorcycle can be a straightforward process if you take the right precautions and follow the steps carefully. Always start by ruling out other issues, test your battery, and then proceed with the jump start. Whether you're using another motorcycle or a car, safety is paramount to avoid any damage.
FAQs
What should I do if my motorcycle doesn't start even after jump starting?
