The Honda XL650V Transalp is a beloved adventure touring motorcycle, known for its versatility and reliability. One crucial aspect of managing its fuel supply, especially on longer journeys where fuel stops might be scarce, is understanding how to utilise the reserve tank. This guide will walk you through the process, ensuring you're never caught short of fuel on your travels.
Understanding Your Fuel Tap
Your Honda XL650V is equipped with a fuel tap, often referred to as a petcock. This device controls the flow of fuel from the main tank and the reserve tank to the engine. It's typically located on the side of the fuel tank, within easy reach of the rider.
The Three Positions Explained
The fuel tap on your XL650V will usually have three distinct positions:
- ON: This is the standard position for normal riding. Fuel flows from the main fuel tank reserve.
- OFF: This shuts off the fuel supply completely. It's good practice to turn the tap to OFF when the motorcycle is parked for extended periods or when performing maintenance.
- RES (Reserve): This position allows fuel to flow from the reserve portion of the fuel tank. You'll use this when your main tank is running low.
When to Switch to Reserve
Knowing when to switch to reserve is key to avoiding a sudden engine cut-out. While it's tempting to wait until the very last moment, it's advisable to switch to reserve when you notice the engine starting to sputter or lose power, indicating the main fuel supply is nearly depleted. Many riders also develop a feel for their bike's range and will switch to reserve proactively based on their mileage.
Estimating Your Reserve Range
The exact amount of fuel in reserve can vary slightly, but generally, the Honda XL650V has a reserve capacity of around 3-4 litres. This typically translates to an additional 60-80 miles (approximately 100-130 km) of riding, depending on your riding style, terrain, and engine condition. However, it's always best to consult your owner's manual for the most accurate information specific to your model year.
How to Turn On the Reserve Tank
The process is straightforward:
- Locate the fuel tap on your Honda XL650V. It's usually a lever situated near the carburettors or on the lower section of the fuel tank.
- Ensure your engine is running or be prepared to start it.
- Carefully move the fuel tap lever from the 'ON' position to the 'RES' (Reserve) position. The movement might be a distinct click or a smooth transition, depending on the design.
- Once switched to 'RES', continue riding. You should notice the engine picking up fuel again and running smoothly.
- Your next priority should be to find a fuel station and refill your main tank as soon as possible.
Important Considerations
- Never ride with the fuel tap in the 'OFF' position unless you intend to stop the engine.
- When you refill the tank, remember to switch the fuel tap back to the 'ON' position. If you forget, you won't be able to draw fuel from the main tank once the reserve is depleted.
- Be aware of your fuel consumption. Regularly check your trip meter to gauge how much fuel you've used and estimate when you might need to switch to reserve.
Troubleshooting Common Fuel Issues
While the fuel tap is generally reliable, you might encounter occasional issues. Here are a few common problems and their potential solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Engine sputtering and dying, even with fuel in the tank. | Fuel tap not fully in 'ON' or 'RES' position. | Ensure the lever is firmly seated in the desired position. |
| No fuel reaching the engine. | Fuel tap is in the 'OFF' position. | Switch to 'ON' or 'RES'. |
| Engine dies after switching to 'RES' shortly after. | Reserve tank is also empty, or the fuel line is blocked/kinked. | Check fuel level, inspect fuel lines for damage or blockages. Clean or replace fuel filter if applicable. |
| Fuel leaking from the fuel tap. | Worn or damaged diaphragm or seals within the fuel tap. | Consider replacing the fuel tap or its internal components. |
Maintaining Your Fuel System
Regular maintenance of your fuel system is crucial for optimal performance and to prevent issues like fuel starvation. This includes:
- Checking fuel lines: Inspect for any cracks, leaks, or kinks. Replace damaged lines immediately.
- Cleaning or replacing the fuel filter: A clogged fuel filter can restrict fuel flow. Consult your owner's manual for its location and replacement interval.
- Checking the fuel tap: Ensure it operates smoothly and doesn't leak. If it feels stiff or leaks, it might need servicing or replacement.
Frequently Asked Questions
Q: How do I know if I'm on reserve?
A: You'll typically switch to reserve when your bike starts to run out of fuel. The fuel tap lever will be moved to the 'RES' position. You'll know you're on reserve because your bike will run again after sputtering or losing power.
Q: What happens if I forget to switch back to 'ON' after refuelling?
A: If you forget to switch back to 'ON', your bike will continue to draw from the main tank until it's empty. Once the main tank is empty, and you haven't switched the tap to 'RES', your engine will stop receiving fuel and die. You'll then need to switch to 'RES' (if there's fuel in the reserve) or refill the tank.
Q: Can I switch to reserve while riding?
A: Yes, you can switch to reserve while riding. It's a common practice when you realise your main tank is nearing empty. Just ensure you can safely reach and operate the fuel tap lever.
Q: How far can I ride on reserve?
A: The exact range on reserve varies, but for the Honda XL650V, it's typically around 60-80 miles (100-130 km). Always aim to refuel as soon as you switch to reserve to avoid running out completely.
Q: My bike is still not getting fuel after switching to reserve. What should I do?
A: If you've switched to reserve and the engine still isn't running, the reserve fuel might be depleted, or there could be a blockage in the fuel line or fuel filter. Check your fuel level and inspect the fuel system for any obstructions.
Conclusion
Mastering the operation of your Honda XL650V's fuel tap, particularly the reserve function, is an essential skill for any owner. By understanding the different positions, knowing when to switch, and performing regular maintenance, you can ensure that your adventures on the road or trail are uninterrupted by fuel-related issues. Always remember to consult your owner's manual for specific details pertaining to your model year and ride safely!
