Converting a faux cover into an added fuel space

The Yamaha V-Max is a powerful motorcycle, but its fuel tank capacity can be a problem for those looking to go on long rides. One solution is to convert the faux cover into an additional fuel tank. Here is a step-by-step guide on how to do this modification:

Step 1: Sourcing a Faux Cover

The first step is to find a faux cover that can be converted. You can either purchase an aftermarket faux tank cover or choose to modify your existing stock faux cover. If you opt for an aftermarket option, be prepared for a potentially bulky and expensive solution. Modifying the stock faux cover, on the other hand, may not add much capacity unless you're willing to remove the airbox to create more room.

Step 2: Sealing the Factory Cap and Vent

If you decide to proceed with the modification, the next step is to seal off the factory cap underneath the seat to prevent leaks. You will also need to stop up the factory tank air vent and add a new air vent to the upper tank. This is an important step to ensure the safety and functionality of your new fuel tank.

Step 3: Connecting the Fuel Lines

Now, you can begin the process of connecting the fuel lines. Take a line from the upper fuel tank and connect it to the stock fuel tank. This will allow the gas to feed in by gravity. With this setup, you can fill the tank from a seated position through the faux tank and extend your mileage.

Step 4: Testing and Fine-Tuning

Before taking your modified Yamaha V-Max out for a ride, it is crucial to test the new fuel system thoroughly. Ensure that all connections are secure and that there are no leaks. Fine-tune the setup as needed, keeping in mind that this modification will affect your centre of gravity. When not going on long-distance rides, you may choose not to fill the upper tank to maintain better handling.

Step 5: Alternative Solutions

While converting the faux cover into an added fuel space is a creative solution, it may not be the easiest or most cost-effective option. There are aftermarket tanks specifically designed for this situation, offering either a rear seat version or a new faux tank cover version. Additionally, you can consider other solutions such as getting a venture differential, adding an external fuel can, or opting for a tour tank that mounts to the passenger backrest.

Using an external fuel can

If you're looking to increase the fuel capacity of your VMax, one option is to add an external fuel can. This is a more affordable solution compared to buying a larger fuel tank, and it can be a good temporary option if you're planning a long-distance trip.

There are a few things to consider if you're thinking of adding an external fuel can to your VMax. Firstly, you'll need to decide on the size and placement of the fuel can. Some people choose to mount the fuel can on a luggage rack at the back of the bike, while others prefer to strap it to the side of the bike or place it in a saddle bag. The size of the fuel can will depend on how much extra fuel you need and the available space on your bike.

When choosing a fuel can, it's important to select one that is made from fuel-resistant material and has a secure lid to prevent leaks. You'll also need to consider how you'll connect the fuel can to the stock fuel tank. Some people choose to use a gravity feed system, where a line is run from the upper fuel tank to the stock fuel tank, allowing the gas to feed in by gravity. This can be a simple and effective solution, but it's important to ensure that the lines are properly connected and sealed to prevent leaks.

Another option is to use a fuel pump to transfer fuel from the external fuel can to the stock tank. This can be more complex to set up, but it allows you to control the flow of fuel more easily. It's important to consult a professional or a mechanic if you're unsure about the best way to connect the fuel can to your bike's fuel system.

Additionally, it's crucial to consider the safety implications of adding an external fuel can to your bike. Fuel is highly flammable, so it's important to ensure that the fuel can is securely mounted and doesn't pose a fire hazard. It's also important to be aware of the weight distribution of your bike, as adding an external fuel can can affect the centre of gravity and handling of your VMax.

Overall, adding an external fuel can to your VMax can be a viable option if you're looking to increase your fuel capacity. However, it's important to carefully consider the placement, connection, and safety implications of this modification to ensure a safe and effective solution.
