Removing Fuel Tank From M109r: Step-By-Step Guide

how to remove fuel tank from m109r

Removing the fuel tank from an M109R motorcycle is a relatively straightforward process, but it is made easier with an extra pair of hands. The first step is to remove the seat and the tank bolts. Next, ensure the fuel valve is in the on position and disconnect the fuel line. It is also important to drain the gas from the tank before proceeding. Once the fuel line is disconnected, the tank can be pulled back and lifted out. It is important to note that there may be additional connections to disconnect, such as electrical wiring or the speedometer, and that care should be taken to avoid damaging any parts during the process.

Disconnect the fuel line

Disconnecting the fuel line is a crucial step in removing the fuel tank from an M109R motorcycle. Here is a detailed guide on how to do it safely and effectively:

First, it is important to prepare the motorcycle for the fuel tank removal process. This includes removing the seat and the tank bolts as per the owner's manual instructions. Ensure that the fuel valve is set to the "on" or "prime" position to drain the gas from the tank.

Now, we can focus on the fuel line. To disconnect the fuel line, start by pinching the two tab ends together. Gently wiggle and pull to detach the fuel line from the pump plug. Be cautious, as a small splash of gas may come out when you initially disconnect the line. It is a good idea to lay a towel over the battery compartment to catch any spills.

With the fuel line disconnected, you can now slowly move the tank forward and lift it slightly. This will allow you to access the connectors and ensure that the rubber donuts are in place before reinstalling the tank.

It is worth noting that there may also be an electrical connection that needs to be disconnected during this process. Having an extra pair of hands can be helpful at this stage to safely manage the fuel tank and disconnect the necessary components.

Overall, disconnecting the fuel line is a straightforward process, but it requires careful attention to ensure no damage is caused to the motorcycle and to avoid any fuel spills. Always refer to the service manual for specific instructions related to your M109R model.

Unplug the fuel pump

To unplug the fuel pump, you will need to first remove the seat and the tank bolts. Ensure the fuel valve is set to the "on" position. Disconnect the fuel line by pinching the two tab ends together and gently wiggling and pulling. You can then pull the fuel tank away from the handlebars a few inches.

Next, lift the dash panel with the speedometer and push it forward towards the handlebars. This will align two pegs into two grommets on top of the tank. Once the pegs are free, you can unplug the speedometer plug. With the dash cover removed, you can now access the fuel pump.

Grab the front and base of the tank and slide it back and away from the handlebars. Be careful not to lose the two rubber discs that guide the fuel pump into place. With the fuel tank moved, you should now be able to unplug the fuel pump.

It is worth noting that some people recommend having four hands for this job, with two people holding the tank and two making the disconnections. This makes the process much easier.

Remove the seat

To remove the seat from your Suzuki M109R, you will need to first locate the seat bolt, which is under the seat. Using the appropriate tool, loosen and remove the bolt. Once the bolt is removed, you can lift the seat and set it aside.

If you are removing the seat as part of a larger project to access other components of your motorcycle, such as the fuel tank, you may need to take a few additional steps. It is recommended that you remove the driver's seat first and set the handlebars straight. This will give you more room to work and access the necessary components.

After removing the seat, you may need to disconnect the fuel line and wire harnesses. To do this, pinch the two tab ends of the fuel line together and gently wiggle and pull to disconnect it. Be careful not to lose any fuel or create a spill. You may want to have a towel or container ready to catch any drips.

Additionally, you may need to remove the speedometer or other dashboard components that are connected to the fuel tank. To do this, lift the dash panel with the speedometer and push it forward towards the handlebars. This will align the pegs with the grommets on top of the tank, allowing you to unplug the speedometer plug and remove the dash cover.

By following these steps, you will be able to successfully remove the seat and access the necessary components of your Suzuki M109R for maintenance or repairs. Remember to work carefully and consult a professional or the owner's manual if you have any questions or concerns.

Drain the tank

To drain the tank of your M109R, begin by removing the seat and the tank bolts as per the Owner's Manual instructions. Ensure that the fuel valve is set to the "on" position. Next, remove the large gas line, also known as the "prime" gas line, from the left side of the carburettor. This is where you will drain the gas from the tank. Move the fuel valve to the "prime" position to completely drain the tank.

Now, you can remove the small gas line from the right side of the carburettor. At this point, you will need to break the seal between the tank and the rubber grommet type rings that hold it in place with the frame. You can do this by pushing, wiggling, and moving the tank around. Be careful not to force it, but a little wiggling may be necessary.

Once the tank is drained and the seals are broken, you can proceed to the next steps of removing the fuel tank from your M109R. It is recommended to have four hands for this process: two to hold the tank and two to make the disconnections.

Disconnect the electrical connection

Disconnecting the electrical connection is a crucial step in removing the fuel tank from your M109R. Here is a detailed guide to help you through the process:

Firstly, before you begin, it is important to gather the necessary tools and create a safe workspace. Ensure you have a clear understanding of the bike's electrical system and consult the service manual if needed. It is also recommended to have a helper, as some steps may require four hands.

Now, locate the electrical connection. It is usually found underneath the fuel tank, close to the fuel line and other connectors. To access it, you may need to remove the seat and any side covers or fairings that obstruct your access. Once you have identified the electrical connection, it's time to disconnect it.

To disconnect the electrical connection, carefully follow these steps:

  • Before disconnecting any electrical components, it is essential to ensure the bike's electrical system is turned off. Check that the ignition is off, and there is no power flowing through the system.
  • Identify the electrical connector. It may have a protective cover or be located near other connectors, such as the fuel line connector.
  • Grasp the electrical connector firmly but gently. Some connectors may have a locking mechanism or tabs that you need to depress or squeeze to release. Refer to your M109R manual for the exact mechanism of your bike's connector.
  • Gently pull or wiggle the connector to detach it from its housing. Be careful not to use excessive force, as this may damage the connector or surrounding components.
  • Once the connector is released, set it aside, ensuring it doesn't dangle or place strain on any attached wires. You may want to label or mark this connector for easy reassembly.

By following these steps, you will have successfully disconnected the electrical connection, which is an important step in safely removing the fuel tank from your M109R. Remember to consult the service manual for additional guidance and always exercise caution when working with electrical systems.
