When your motorcycle’s battery is dead or you find yourself stuck in a remote location without a jump starter, one solution that can get you back on the road is a technique known as “bump start.” Often a last resort, bump starting is a method of starting a motorcycle without relying on the electric starter, which is especially handy when you’re in a bind. But how exactly does this technique work, and is it still effective with modern motorcycles? In this article, we’ll take a deep dive into the mysteries of bump starting modern motorcycles, explaining what it is, when to use it, and how to do it safely and efficiently.
A bump start, also known as a push start, involves manually getting your motorcycle’s engine to turn over by pushing it and then engaging the clutch. Unlike the traditional method of starting a motorcycle by using the electric starter, a bump start relies on the power generated from the momentum of the bike. While bump starting was once a common practice, especially for older motorcycles, its relevance with modern machines is frequently questioned. However, it’s still a useful technique in certain situations.
While modern motorcycles are designed with reliable starting systems, there are still times when you might find yourself needing a bump start. Here are a few reasons why it’s beneficial to know how:
Bump starting a motorcycle may seem complicated, but with the right steps and precautions, it can be done safely and effectively. Below is a step-by-step guide to bump starting a modern motorcycle.
Before you begin, make sure the issue is with the battery and not something else, like a mechanical failure. Also, check that there are no other problems, such as a stuck throttle or faulty electrical components.
It’s important to ensure you’re in a safe location. Ideally, find a flat, clear space where you have enough room to get your motorcycle moving. Avoid areas with traffic or obstacles that could pose a danger during the process.
Wear protective gear such as gloves and sturdy shoes. It’s also recommended that you have a riding partner to assist you in the bump start, though it can be done alone with the right conditions.
Once you’ve assessed the situation, put your bike in second gear. Second gear is preferred because it offers a good balance of torque and control. Ensure the clutch is fully engaged to prevent the engine from turning over prematurely.
With the clutch pulled in, begin pushing the motorcycle forward to build up momentum. If you’re doing this alone, you can either push the bike by yourself or use a downhill slope to assist with speed. The goal is to get the bike moving fast enough for the engine to turn over.
Once you’ve gained enough speed (typically around 5-10 mph), quickly release the clutch while giving the throttle a small twist. This should cause the engine to “fire up” as the momentum forces the engine to rotate. Be ready to pull in the clutch again to keep the engine running once it starts.
Once the bike has started, give the throttle a gentle twist to keep the engine running. You may need to rev the engine slightly to stabilize the idle before riding off.
While bump starting is generally straightforward, there are a few issues that can arise, especially with modern motorcycles. Here’s how to troubleshoot common problems:
If the engine doesn’t start after a couple of attempts, check the following:
If your motorcycle starts but quickly stalls after releasing the clutch, this could indicate a more serious issue such as:
If your motorcycle starts but runs poorly after bump starting, it could indicate a problem with the ignition system or the fuel delivery system. You may need to get the bike checked by a professional mechanic to identify and resolve the underlying issue.
While bump starting is generally safe for most motorcycles, it’s important to remember that modern motorcycles are designed with advanced electronics and fuel injection systems, which can make the process a bit more complicated. Here’s what you should consider:
Knowing how to bump start a motorcycle is a valuable skill for any rider, especially in situations where you find yourself without access to a working battery or jump starter. While the process has evolved alongside modern motorcycles, understanding the fundamentals of a bump start can save you in an emergency. However, it’s important to ensure that your bike is in good condition and that you’re not attempting this method when there’s a more serious issue at play.
If you’re still unsure about how to perform a bump start or encounter any complications, don’t hesitate to refer to your bike’s manual or consult a professional mechanic for advice. Additionally, for more detailed information about motorcycle maintenance, you can explore reliable repair guides and ensure you are prepared for every ride.
Ultimately, while bump starting is a handy technique to know, always make sure that your motorcycle’s battery is well-maintained to avoid such situations in the future. Happy riding!
