Step 1: Remove the gas tank
This is a straightforward step but one that many people overlook—because they’re considering modifying their gas tank before it’s removed from the bike.
So, here are some reasons why you shouldn’t modify the gas tank until it’s removed from the bike:
1) It’s not safe! You can’t see what you’re doing, and you might cut yourself or hurt yourself with sharp edges or other tools.
2) It’s easier to work on if it isn’t attached to anything! You’ll have more room to move around and maneuver things as needed, which means fewer space constraints while working on something like drilling holes or sanding down areas, so they’re smooth enough for paint/paint primers/paint itself (or whatever other type of coating you choose).
Step 2: Clean the gas tank thoroughly.
The second step is to thoroughly clean the outside of your tank with warm water and soap. Be sure to take care not to damage any paint or decals on the exterior of your tank.
If there are rust spots or other grime on the exterior, you can remove them with a wire brush or sandpaper, but I’d only recommend this if it’s covering up a good paint job—otherwise, leave it alone.
After you’ve cleaned off all the crap from your gas tank, take some time to wash out your filter (if you have one). If it’s filthy, you can soak it in hot soapy water for a few minutes before replacing it with its housing.
Step 3: Apply tar or primer to the gas tank.
You can make sure that your gas tank is in great shape for years to come by taking care of it now. One way to do this is by applying primer to its surface. This will help seal any holes or leaks in the metal, preventing corrosion from getting into the tank and causing damage.
First, you’ll want to clean off any rust or dirt from the tank before applying primer. Afterward, apply tar or primer over the surface of your gas tank with a flat paintbrush and painting mask so that you don’t get any onto other parts of your car while working on this project!
Step 4: Paint the gas tank.
In our case, we’ll use black primer and a base coat.
First, apply your base coat. In this case, we’ll be using black. Allow it to dry completely overnight before moving on to the next step.
After that, apply your primer. Again, allow it to dry completely before moving on to the next step.
Step 5: Heat the painted gas tank.
To make your motorcycle gas tank shine again, you’ll need to use heat and paint to get the tank looking its best.
First, heat the tank with a heat gun. The paint on the gas tank will be the most challenging part of making this motorcycle gas tank look new again. Use a heat gun to flex the color back into place slowly. I also recommend using an air blowgun to remove any air bubbles under the paint.
Step 6: Reinstall the fuel line, if applicable.
The fuel line of your motorcycle might be a bit simpler to reinstall than it was to remove, but it is still somewhat difficult and will require you to be patient and precise.
First, you’ll need to remove the old fuel line. There should be a clamp at the end of the line that you can loosen with a wrench or some other appropriate tool for removing clamps. Once the clamp is off, slide the old bar off of its connection point on your motorcycle.
Then, take your new fuel line (which should come with instructions for installation) and align it with the connection point on your bike. Make sure all your parts are lined up correctly, then tighten down any clamps or fasteners as necessary so that everything stays in place.
Finally, test your newly installed fuel system by turning on your engine!
Step 7: Install new decals, if applicable.
If applicable, you need to install the new decals or paint over the old ones. This is a small detail and depends on your bike type and what kind of artwork you want on your gas tank. It would help if you also painted over any logos or tags that may be on the gas tank. If your gas tank has no decals, then skip this step and go on to step 8.
Step 8: Apply sealant to the inside of the tank.
Motorcycle gas tanks are made of steel and have a smooth coating. This is done to help protect against rust that can affect the bike. If you damage your tank and it needs to be repaired, applying sealant after welding will prevent rust from forming. Just make sure that you get the kind of sealant that is meant for use with metal surfaces!
How to apply a sealant to the inside of the tank?
1. Make sure the tank is clean, dry, and cool to the touch.
2. Wipe the inside of the gas tank with a clean rag. And some solvent to remove any dirt or oil on the surface.
3. Pour a small amount of product into a plastic container and mix it with a few drops of water until you get a thin paste (be careful not to add too much water).
4. Using an old toothbrush, apply a thin layer of sealant around your seams, edges, and corners to create a barrier between them and any moisture present in your tank that could cause rusting over time. This may take some time if there are many large surfaces within your gas tank, so make sure you don’t use too much sealant at once so as not to waste any product!
Step 9: Reattach the cap and petcock.
Before you start the bike, turn on the fuel tap to make sure you hear a steady stream of fuel flowing through the line. If you don’t hear anything, check that there are no air bubbles in your fuel line and try again.
After you’ve confirmed that nothing is blocking your fuel flow, please turn off the tank valve and close up your gas tank by reattaching its cap and petcock.
Step 10: Refill with fuel and test ride.
You’ve made it! You’re done! Now all you have to do is fill your gas tank with fuel, put the lid on, and ride it around for a bit. This will let you make sure that everything is working correctly. If something is wrong, you can fix it before you start riding around on the road.
Suppose everything looks good, congratulations! You have successfully modified your motorcycle gas tank!
Modifying a motorcycle gas tank may seem complicated, but following these steps is easy. And you’ll have a fantastic custom gas tank in no time!
