Understanding Push Starting
Definition of Push Starting
Push starting, or bump starting, is a method used to start a motorcycle with a dead or weak battery by using physical momentum. This technique harnesses the kinetic energy generated by the bike moving forward to turn the engine over and initiate combustion, effectively bypassing the need for electric power from the battery.
Mechanics of Push Starting
The process involves engaging the bike’s transmission while it is in gear, allowing the rear wheel to rotate the engine as the bike gains speed. When done correctly, the engine will start as the clutch is released, and the motorcycle can be ridden away.
This method is particularly useful in situations where an electric start is not possible due to battery failure.
When Not to Push Start
Push starting is not advisable in certain situations. If there are other mechanical issues preventing the engine from starting, such as a malfunctioning fuel system or ignition problems, push starting will be ineffective.
Additionally, if the battery is completely dead with no electrical power, the bike may not start even with push starting. It is also important to note that motorcycles equipped with automatic transmissions cannot be push started.
Statistics on Battery Failure
| Battery Failure Causes | Percentage of Riders Affected |
|---|---|
| Leaving lights on | 35% |
| Old battery | 30% |
| Faulty charging system | 25% |
| Fuel issues | 10% |
The statistics above highlight the common causes of motorcycle battery failures. A significant number of riders find themselves in situations where they need to push start due to leaving their lights on or having an old battery.
It underscores the importance of regular battery maintenance and checks, especially before long rides or trips. Understanding these causes can help riders prevent unexpected failures and the need for push starting.
Preparing for a Push Start
Safety Checks
Before attempting to push start your motorcycle, it is crucial to perform several safety checks. Ensure that the kill switch is in the “run” position, the kickstand is up, and there are no obstacles in the path where you plan to push start.
Wearing appropriate riding gear, including a helmet, is also essential for safety.
Ensuring Fuel and Battery Status
Double-check that there is sufficient fuel in the tank and that the battery has at least some charge. If the lights on the dashboard are glowing faintly, it indicates that the battery still has some life.
If the battery is completely dead, push starting may not work. Additionally, ensure that the fuel petcock is set to “on” for older motorcycle models.
Required Gear and Environment
Choose a safe and suitable environment for push starting. Ideally, this should be a flat or slightly downhill area with enough space to build momentum.
If possible, enlist the help of a friend to push the motorcycle, making the process easier. If you’re alone, ensure you can push the bike while jumping on it safely.
| Pre-Push Start Checklist | Status |
|---|---|
| Kill switch set to “run” | ✔️ |
| Kickstand up | ✔️ |
| Sufficient fuel | ✔️ |
| Battery charge present | ✔️ |
This checklist provides a clear overview of essential checks to perform before attempting to push start a motorcycle. Ensuring that each item is checked off can prevent unnecessary effort and frustration.
A simple oversight, such as leaving the kill switch in the wrong position or not having enough fuel, can hinder the push start process.
Step-by-Step Guide to Push Starting
Step 1: Turn On the Ignition
Start by ensuring that the ignition is turned on. This is crucial as it allows the electrical components, including the fuel pump and ignition system, to operate.
If the ignition is off, the motorcycle will not start, regardless of how fast you push it.
Step 2: Select Gear
Engage either second or third gear. Second gear is generally recommended for most motorcycles as it provides a better balance of torque and speed needed to turn the engine over.
Avoid using first gear as it can cause the rear wheel to lock up, especially on higher compression engines.
Step 3: Start Pushing
Hold the clutch in and begin pushing the motorcycle forward. If you have a friend, they can help push you to build momentum.
Aim to reach a speed of about 5 to 10 miles per hour, which is typically sufficient for a successful push start.
| Recommended Speed for Push Starting | Recommended Gear |
|---|---|
| 5-10 mph | 2nd or 3rd gear |
This table outlines the ideal conditions for successfully push starting a motorcycle. Achieving a speed of 5-10 mph helps ensure that the engine can turn over effectively.
Using the right gear minimizes the risk of damaging the transmission and maximizes the chances of a successful start.
Step 4: Release the Clutch
Once you reach the desired speed, quickly release the clutch. This action will engage the engine and should start the motorcycle.
If done correctly, you will hear the engine kick to life. It may take a few attempts, so patience is key.
Step 5: Rev the Engine
Once started, immediately pull the clutch back in and rev the engine to prevent stalling. This helps to maintain momentum and recharge the battery, ensuring that the motorcycle stays running.
Ride for a short distance to allow the system to stabilize.
Common Mistakes to Avoid
Using the Wrong Gear
Using the wrong gear, particularly first gear, is a common mistake that can lead to failed attempts at push starting. First gear can lock the rear wheel, making it difficult to turn the engine over.
Always opt for second or third gear to minimize this risk.
Forgetting the Kill Switch
Many riders forget to check the kill switch, which can prevent the motorcycle from starting. Always ensure that the kill switch is in the “run” position before attempting to push start.
This simple step can save time and effort.
Not Having Enough Momentum
Failing to build sufficient speed before releasing the clutch is another common mistake. The bike needs to reach a speed of at least 5-10 mph to effectively turn the engine over.
Take the time to ensure you have enough momentum before attempting to start the bike.
| Mistake | Consequence |
|---|---|
| Using 1st Gear | Rear wheel locks up |
| Forgetting Kill Switch | No electrical power |
| Insufficient Momentum | Engine does not turn over |
This table highlights the common mistakes and their potential consequences when attempting to push start a motorcycle. Understanding these pitfalls is critical for riders to avoid frustration and ensure a successful push start.
By being aware of these issues, riders can prepare more effectively and enhance their chances of getting back on the road quickly.
Enhancing Your Push Starting Technique
Proper Body Positioning
Body positioning plays a significant role in the success of push starting. When preparing to release the clutch, slightly shift your weight forward on the bike.
This can help create more traction on the rear wheel, increasing the chances of a successful start.
