How To Remove a Dirt Bike Gas Tank

Removing the dirt bike gas tank makes regular maintenance easier, especially when you need to access the cylinder top area. It is also a good idea to remove the fuel tank for deep cleaning the dirt bike to prevent corrosion and dirt buildup under the tank.

To remove the dirt bike gas tank, you first need to remove the dirt bike seat. Next, remove the top plastic set and radiator shrouds. Finally, disconnect the fuel supply and unscrew the final bolt holding the dirt bike gas tank in place. You can now remove the dirt bike gas tank off the dirt bike.

Next, let’s go over the 5 steps it takes to remove the dirt bike gas tank in detail.

Step 1: Remove the Seat

Let’s begin by removing the seat off the dirt bike. Firstly, the dirt bike seat is usually held in place with a screw on both sides on the dirt bike. In addition to this, some models may have the screw or a clip under the seat inside the fender. The front of the seat usually is held in place by a slide in bolt on the dirt bike gas tank and a groove in the seat.

After removing the screws, slide the seat towards the rear of the dirt bike and it should lift off easily.

Step 2. Remove Plastics From the Dirt Bike Gas Tank

Now, depending on what you plan to do next, you may not need to remove the dirt bike plastics from the dirt bike gas tank. Instead, you have the option to only remove the bolts that connect the plastics into the radiator shrouds. As a result, the plastics will lift off with the gas tank. But in our example, we will remove the plastics completely to be able to clean the gas tank easier.

Remove the screws holding the plastics on the dirt bike gas tank. The bolts are aluminum and screw into the gas tank plastic material. Be careful when removing and putting them back and do not over tighten.

Step 3. Remove Plastics From the Radiator Guards

Next, locate and remove the screws that connect the plastics into the radiator guards. Depending on the guards, you may need to remove the guards completely or just open the bolts on the outer side.

Step 4. Disconnect the Fuel Hose From the Dirt Bike Gas Tank

With fuel injected dirt bikes, the fuel hose usually has a quick disconnect clip in the middle of the fuel hose. There should be a metal clip that you push and it breaks the fuel line.

In carburetor dirt bikes, you have a simple fuel hose and possibly a fuel filter. I usually remove the fuel hose directly from the carburetor side that has the small clamp holding it in place.

Shut off the fuel valve if you have one, and remove the clamp holding the fuel hose in the carburetor. Pull the fuel hose off the carburetor. Sometimes the fuel hose is stuck and may be difficult to pry off. In this case, find a large flat head screwdriver to help remove the fuel hose.

Step 5. Remove the Dirt Bike Gas Tank

Finally, locate the bolt that is holding the dirt bike gas tank in place. Basically most gas tanks are held in place by a bolt in the middle of the gas tank on the top side.
