Riding a dirt bike can be exhilarating, but it all begins with a crucial step: starting the engine. Whether you’re a beginner or a seasoned rider, knowing how to properly start your dirt bike is essential for maintaining its longevity and ensuring your ride is smooth. In this detailed guide, we will walk you through all the essential steps to starting a dirt bike, from electric starts to kickstarts, cold starts, hot starts, and everything in between.
1. Types of Dirt Bikes and Starting Methods
Before diving into the step-by-step starting procedures, it’s important to understand the two main types of dirt bikes: 2-stroke and 4-stroke engines. Both have their unique starting methods, and each requires specific care to get going.
Electric Start vs. Kickstart
- Electric Start: This is the simplest and most modern way of starting a dirt bike. Simply press a button, and the bike will fire up. While it’s convenient and easy to use, it’s not always available on all dirt bikes, especially older or more rugged models.
- Kickstart: The traditional method of starting a dirt bike. If your bike has a kickstarter, you’ll need to use your foot to initiate the engine’s movement. Kickstarting can be tricky if you don’t know the proper technique, so let’s break it down.
2. Kickstarting a Dirt Bike: Step-by-Step Process
Kickstarting may seem daunting, especially if you’re a beginner, but it’s a straightforward process once you understand the mechanics. Here’s how to start your dirt bike using a kickstarter:
Step 1: Turn on the Gas Petcock
First, ensure that the gas petcock (or fuel valve) is turned on. This allows fuel to flow into the engine. Be mindful that some dirt bikes may have separate fuel valves, while others have a combined petcock and fuel shutoff switch.
Step 2: Pull Off the Choke
The choke is designed to increase fuel flow when starting a cold engine. If your bike has a choke, make sure it is pulled out. This step is particularly important for 4-stroke engines, which need extra fuel to start in cold conditions.
Step 3: Mount Your Bike
Position yourself on the bike. Make sure you’re balanced and steady. You don’t want to be too loose on the bike, as it could make kickstarting harder.
Step 4: Press the Kickstarter
Now, place your foot on the kickstarter lever. Press it down slowly a couple of times to build compression within the engine. Once you feel resistance, it’s time to give the kickstarter a full press.
Step 5: Kickstart with Full Force
Now, with all your weight, push down firmly on the kickstarter. If done correctly, the bike should fire up. If it doesn’t start immediately, repeat the process a few more times.
3. Starting a Dirt Bike with Electric Start
Electric starting is a lot easier than using a kickstarter. It’s the push-button option that many modern bikes have. If your bike is equipped with an electric start, follow these steps:
Step 1: Turn on the Gas Valve
As with kickstarting, you first need to ensure the fuel valve is open and the bike is receiving gas.
Step 2: Engage the Choke (If Needed)
If it’s a cold start, engage the choke to ensure the bike gets extra fuel. However, if the engine is warm, you can skip this step.
Step 3: Press the Start Button
Now, simply press the start button. The electric current flows to the starter motor, which engages the engine. The bike should start without much effort on your part.
4. Starting a 2-Stroke Dirt Bike
Starting a 2-stroke dirt bike is generally easier than a 4-stroke due to the engine’s simpler design. Here’s how to get it going:
Step 1: Shake the Fuel
Before turning on the gas, gently shake the bike to ensure the fuel and oil mixture is well-mixed. Over time, these fluids can separate, making the bike harder to start.
Step 2: Turn on the Gas Valve
Now that the fuel is well-mixed, turn on the gas petcock. Pull out the choke if you’re starting the bike from cold.
Step 3: Kickstart the Engine
Place your foot on the kickstarter and press it down gently a few times to build compression. Then, use your full body weight to kickstart the engine. If done correctly, the engine should start up.
5. Cold Start Procedure for 4-Stroke Dirt Bikes
When starting a cold 4-stroke engine, it’s crucial to follow these steps for a smooth start:
Step 1: Turn on the Gas Valve
Just like with other starting methods, make sure the gas valve is turned on.
Step 2: Engage the Choke
Pull the choke to provide extra fuel to the engine.
Step 3: Twist the Throttle (If Needed)
Some liquid-cooled 4-stroke engines may require an additional twist of the throttle to prime the carburetor with fuel. Twist the throttle twice to make sure it has enough gas to start.
Step 4: Kickstart the Bike
Now, use the kickstarter to start the bike. Press down slowly and steadily on the kickstarter. Avoid using the throttle during this process.
6. Hot Start Procedure for 4-Stroke Dirt Bikes
If your 4-stroke dirt bike is already warm but has stalled, don’t worry—it’s easy to restart. Here’s the hot start procedure:
Step 1: Turn Off the Choke
Unlike the cold start, the choke should not be engaged when the engine is hot. Make sure the choke is turned off.
Step 2: Find the Hot Start Lever
Many modern dirt bikes have a hot start lever, usually located near the carburetor. This lever helps flood the engine with extra fuel, making it easier to start a hot engine.
Step 3: Kickstart the Engine
With the hot start lever engaged, kick the bike as you normally would. The bike should start without too much effort.
7. Dealing with a Flooded Dirt Bike
If your bike is flooded (too much fuel has entered the engine), it won’t start. Follow these steps to clear a flooded engine:
Step 1: Turn Off the Gas Valve
First, turn off the gas valve to stop any more fuel from entering the engine.
Step 2: Remove the Spark Plug
Take off the spark plug, wipe it dry, and clear any excess fuel from the engine.
Step 3: Open the Throttle
While the bike is in neutral, open the throttle fully and kickstart the bike. This will allow any excess fuel to be expelled from the engine, and the bike should start.
8. How to Start a Dirt Bike Without a Kickstart
If both the electric start and kickstarter aren’t working, you might be in a pinch. Here’s how to start the bike without either:
Step 1: Turn Off the Choke
Ensure the choke is off and the bike is in neutral.
Step 2: Push Start the Bike
Push the bike quickly to build speed. Jump onto the bike while it’s moving and engage the clutch.
Step 3: Release the Clutch
Once you’re on the bike, release the clutch while the bike is in second gear. This will force the engine to start.
9. Starting an Air-Cooled Dirt Bike
Air-cooled engines can be a bit trickier to start, but once you understand the process, it gets easier. Here’s what to do:
Step 1: Turn On the Gas Valve
Ensure the gas valve is open, and the fuel is flowing properly.
Step 2: Engage the Choke
Pull out the choke to increase fuel flow to the engine.
Step 3: Kickstart the Bike
Find the top dead center (TDC) of the piston, then give the bike a full kick to start the engine.
5. Common FAQs About Starting a Dirt Bike
1. How can I tell if my bike is flooded?
If your dirt bike doesn’t start after several attempts and you smell fuel, it’s likely flooded. Follow the steps to clear the flood by removing the spark plug and kicking the bike with the throttle wide open.
2. Why does my dirt bike not start when it’s hot?
If your bike doesn’t start when it’s hot, it may need a hot start lever. Use the hot start procedure to ensure more fuel reaches the engine.
3. What should I do if my kickstarter is stuck?
If the Kickstarter feels stuck, check for mechanical issues like jammed parts or low engine compression. You may need to consult a mechanic.
4. Can I start a dirt bike without gas?
No, starting a dirt bike without gas will not work. Ensure that your bike has an adequate fuel supply before attempting to start it.
5. How often should I service my dirt bike?
Regular maintenance is key to keeping your dirt bike in good shape. Perform routine checks on the engine, air filter, oil, and spark plug every 10-15 hours of use or as recommended by the manufacturer.
Conclusion
Starting a dirt bike doesn’t have to be intimidating once you understand the basics. Whether you’re working with a 2-stroke, 4-stroke, kickstart, or electric start bike, each method has its own set of procedures. By following the right steps and maintaining your bike regularly, you’ll ensure that every ride is smooth and enjoyable.
Happy riding!
