Replacing The Main Fuel Line In Your Honda Recon 250

If you're looking to replace the main fuel line on your Honda Recon 250, you've come to the right place. This is a step-by-step guide on how to do it. First, locate the fuel filter, which is on the main fuel line from the gas tank to the carburettor, close to the top of the engine and on the frame rail on the driver's side. Next, remove the fuel tank by undoing the snorkel, two bolts at the front of the tank, and possibly the fuel tap screw. Then, remove the old fuel line from the tank and carburettor, and install a new one, considering adding a fuel filter as well. Finally, refill the tank with fresh fuel, and you're done! It is recommended to also clean the carburettor and fuel tank while you're at it, to ensure optimal performance.

Cleaning the carburettor

To clean the carburettor of your Honda Recon 250, you will need to remove it from the ATV. This will involve disconnecting the fuel hose from the carb and the tank valve. You may also need to remove the bowl and the jets.

Once the carburettor has been removed, use carburettor cleaner and Q-tips to clean it out thoroughly. You can also try blowing air through the carburettor to remove any remaining debris. If the carburettor is particularly dirty or clogged, you may need to soak it in carburettor cleaner overnight.

It is important to check all components of the carburettor for any signs of damage or wear. This includes the float, needle, and inlet. Ensure that the float moves freely and that the needle is not stuck. You should also check that the inlet is open and free of obstructions.

If the carburettor is still not functioning properly after cleaning, you may need to adjust the pilot screw or the idle mixture screw. The pilot screw can be adjusted to change the amount of fuel entering the carburettor, while the idle mixture screw affects the air-fuel mixture at idle.

Additionally, it is recommended to clean or replace the fuel filter, fuel lines, and petcock to ensure that the fuel system is free of contaminants and functioning properly.

• When reassembling the carburettor, ensure that all components are correctly installed and secured. This includes the choke, jets, and float bowl.
• Use a flashlight to inspect the carburettor for any signs of damage or debris.
• Wear safety goggles when working with carburettor cleaner, as it can spray back at you.
• Allow the carburettor to dry thoroughly before reinstalling it.
• Refer to a service manual or seek assistance from a qualified mechanic if you are unsure about any aspect of the cleaning or reassembly process.

Replacing the fuel line

To replace the main fuel line on a Honda Recon 250, you will need to purchase a suitable replacement fuel line. You can find these at some auto parts stores or online. It is also recommended to get a clear inline fuel filter to go with the new fuel line.

Once you have the necessary parts, follow these steps:

• Remove the fuel tank: This will involve removing the snorkel, two bolts at the front of the tank, and possibly a screw that holds the fuel tap in place.
• Drain the fuel: Pour the old fuel into a suitable container and dispose of it properly.
• Clean the fuel tank: Use fresh fuel or a fuel cleaner to rinse out the tank, removing any dirt, sediment, or gunk that has built up.
• Inspect and clean the petcock: Remove the petcock from the fuel tank. Spray carb cleaner and compressed air through the long tube to clean it. Also, make sure to clean the screen on the petcock.
• Replace the fuel line: Cut the old fuel line and join the new fuel line to it, splicing in the inline fuel filter about 1.5 to 2 inches above the carburetor. Use appropriate connectors to join the old and new fuel lines securely.
• Reinstall the fuel tank and petcock: Make sure to connect the fuel line to the carburetor and secure it with a hose clamp.

By following these steps, you should be able to successfully replace the main fuel line on your Honda Recon 250.

Removing the fuel tank

To remove the fuel tank from a Honda Recon 250, you will need to first remove the snorkel. Then, you will need to remove the two bolts at the front of the tank, located just behind the head race. Depending on the model of your Honda Recon 250, you may also need to remove the fuel tap, which is held by a single crosshead screw in the middle.

Once the bolts and fuel tap have been removed, you can lift the tank to access the other end of the fuel line attached to the tap. It is worth noting that it is almost impossible to get all the fuel and dirt out of the fuel tank due to its shape, but there are small filters on the tap inlets.

When reinstalling the fuel tank, take care to ensure that the rubber fuel line is securely connected to the carb nipple. A hose clamp can be used to secure the connection, but be careful not to overtighten it, as this can damage the fuel line.

Checking the fuel filter

To check the fuel filter on a Honda Recon 250, you must first locate it. The fuel filter is situated on the main fuel line, which runs from the gas tank to the carburettor. It is positioned close to the top of the engine, on the frame rail, and on the driver's side.

Once you have located the fuel filter, you can begin your inspection. Start by examining the condition of the fuel line. It should be soft and flexible. If the fuel line is hard or stiff, it may need to be replaced. Check for any signs of damage, cracks, or leaks.

Next, you will need to inspect the fuel filter itself. Look for any signs of debris, dirt, or build-up that may be blocking the filter. If the filter appears dirty or clogged, it will need to be cleaned or replaced.

To clean the fuel filter, you can use a specialised fuel system cleaner or a fuel additive, such as Sea Foam. These products help to dissolve and remove any built-up dirt, carbon deposits, or contaminants from the fuel system, including the filter.

It is important to note that cleaning or replacing the fuel filter alone may not be sufficient to resolve fuel-related issues. Other components of the fuel system, such as the fuel tank, fuel lines, carburettor, and fuel petcock, should also be inspected and cleaned or replaced if necessary.

Additionally, it is recommended to use a fuel stabiliser or preservative to maintain fuel quality and prevent fuel-related problems. Products such as Klotz Octane Booster contain a fuel preservative and synthetic lubricant, which can help prevent clogged fuel jets and maintain engine performance.

Adjusting the idle

First, locate the idle screw on the right side of the carburettor. This will be a flat-head screw, which you can turn to adjust the idle speed.

Next, start the ATV and let it run for at least five minutes to warm up. It is important to ensure the vehicle is warmed up before adjusting the idle, as a cold engine can affect the idle speed.

Now, turn the screw to the right to raise the idle speed, and to the left to lower it. Make your adjustments in small increments, as a little adjustment can go a long way. Check the results after each adjustment to ensure you don't go too far.

Additionally, it is worth noting that the idle screw may not be the only issue affecting your ATV's performance. A dirty carburettor, clogged fuel lines, or a vacuum leak can also impact the idle speed and overall performance. Therefore, it is recommended to perform regular maintenance and cleaning of these components to ensure optimal performance.
