Bump starting an ATV involves using forward momentum and the transmission to manually turn the engine over and get it running when the battery is dead or another starting source isn't available.
Bump starting is a useful technique, particularly when you find yourself without a working battery source for your ATV. As noted, "Bump starting is another option if you have no other battery source available." This method bypasses the electric starter by harnessing the vehicle's motion to rotate the engine's crankshaft.
Understanding the Concept
The core idea behind bump starting, also known as push starting, is relatively simple. "This technique involves getting the quad moving, then quickly engaging and releasing the clutch to start the engine." When the ATV is rolling, and you suddenly connect the transmission to the engine via the clutch, the wheels force the engine to turn. "The forward momentum and the quick release of the clutch will rotate the engine and, hopefully, start it."
Step-by-Step Guide to Bump Starting
Executing a successful bump start requires coordination and momentum. Here are the general steps:
- Ensure ATV is in Gear: Place the ATV in a suitable gear, typically second or third. Avoid first gear as it can cause the rear wheels to lock up.
- Get Momentum: Get the ATV rolling forward. This can be done by pushing it, preferably downhill if possible, or having one or more people push it on flat ground. You need enough speed to turn the engine over.
- Engage the Clutch: Once the ATV has sufficient momentum, quickly engage the clutch lever (pull it in).
- Quickly Release the Clutch: While the ATV is still rolling, rapidly release the clutch lever. This action links the spinning wheels to the engine.
- Engine Turnover: If done correctly and with enough speed, releasing the clutch will force the engine to rotate.
- Engine Starts: If the engine fires, immediately pull the clutch back in and apply the brake to control the ATV. Allow the engine to idle to confirm it's running.
- If It Doesn't Start: If the engine doesn't start on the first attempt, re-engage the clutch while the ATV is still rolling (if possible) or stop and repeat the process, trying to achieve greater momentum.
Practical Tips for Success
- Find a Slope: A slight downhill slope makes getting the necessary momentum much easier.
- Have Help: Having someone push the ATV can provide more speed and make the process less strenuous.
- Check Fuel and Ignition: Ensure you have fuel in the tank and the ignition is turned to the 'ON' position.
- Safety First: Be prepared to control the ATV as soon as it starts. Bump starting on uneven or slippery ground can be dangerous.
- Try Different Gears: If one gear doesn't work, try a slightly higher or lower one, but stick to the mid-range (2nd or 3rd).
Here is a summary table of the key steps:
| Step | Action |
|---|---|
| 1 | Select a mid-range gear (e.g., 2nd or 3rd). |
| 2 | Get the ATV rolling with good momentum. |
| 3 | Quickly engage the clutch. |
| 4 | Quickly release the clutch. |
| 5 | Be ready to pull the clutch back if it starts. |
Bump starting is a valuable skill for any ATV rider but should be used cautiously and only when other starting methods are unavailable.
