If you have a hand painted motorcycle, most of the paint is on the gas tank. Unfortunately, this is also the area most prone to dents and dings. Having a dented motorcycle gas tank professionally repaired is expensive, not to mention the fact that you'll be without your bike while it's being repaired. Before you call a repair shop, try getting the dent out yourself with this automatic dent repair trick that pulls out dents without damaging your paint job.
Cylinder cooling
Rice. 2. Installation of shields on cylinder 1 - cylinder; 2 — shields.
There is not enough air flow to the rear of the motorcycle engine cylinder. To cool it better, it makes sense to make two shields from tin and strengthen them, as shown in Fig. 2. The shields must match the height of the cylinder.
Removing dents without painting on a motorcycle
- Your motorcycle will not fall into the category of broken and painted, which means it will not lose value when sold.
- Paintless repairs are much more cost-effective (no putties, primers, paints, varnishes, consumables, or colors are used), faster (takes 15 minutes) and more environmentally friendly (without the use of solvents and other toxic substances) than traditional body repairs.
- There is no risk of discolouration since repainting is not required.
- The motorcycle will retain its original finish and corrosion protection.
What dents can be removed?
The main condition for removing dents without painting is that the paint layer on the tank should not be damaged. Dents with paint damage can be repaired using traditional body repair.
The damaged area should not have been painted or puttied until this point.
Remember that the fresher the dent (and your motorcycle), the better the effect of the VDR repair. Old damage is difficult to correct and comes back over time. This is due to the mechanical memory property of body metal.
Small, shallow dents with smooth outlines are most easily removed. Sharp edges and creases (places of strong tension, metal tightness) complicate the work. Some acute and deep injuries can only be eliminated using the traditional method.
Technology for removing dents without painting on a motorcycle
Recesses on the gas tank are removed using glue, vacuum or using hooks.
With the adhesive method, an applicator is glued to the damage, which is connected to a tool, and when impacted by this tool, it flies off, pulling out a dent with it.
When using a vacuum tool, a suction cup is placed on the dent, which pulls it out.
Excess drawn out metal is settled with a rubber mallet with a plastic core.
The hooks work on the tank from the inside through the neck, but the inside of the tank has an anti-corrosion coating, which makes work difficult.

Do-it-yourself dent removal on a motorcycle
Is it possible to straighten a damaged tank without painting it yourself?
Answer: possible, but not always effective. Usually you can repair only very minor damage with your own hands.
It is popular to eliminate tank irregularities using water or compressed air.
Water
The tank is filled to capacity with water, as a result of which it straightens under its pressure.
Ice
In this case, the tank is filled with water in the same way and then sent outside or to the freezer. When freezing, water expands in volume (by about 30%) and straightens the walls of the gas tank.
Compressed air
With this method, compressed air is supplied to the tank through a hose, and the damage is leveled out.
When using such methods, there is a very high risk of creating new damage, inflating the gas tank, and, if frozen, completely rupturing it.
It’s faster and cheaper to turn to professionals for help!

Small dents on the fuel tank can be repaired as follows:
The tank is removed from the motorcycle and, after closing the drain valve, it is filled with water to the edge of the neck, into which a wooden plug well fitted to its inner diameter is then inserted (Fig. 3). Then you need to drive the plug into the tank with a sharp blow of a hammer. At the moment of impact, a lot of pressure is created inside the tank, and the dents are eliminated. Don't forget to place an elastic spacer between the tank and the surface of the workbench.

Motorcycles are very popular in Latvia. Evidence of this is the many thousands of spectators gathering for the races and the large number of cars on the roads of the republic. And it is no coincidence that the popular science magazine “Science and Technology”, published in Riga, publishes materials for motorcyclists. We offer readers several tips from engineer A. Ribovsky published on its pages.
Tips for choosing and applying putty correctly
Motorcyclists for the most part very often choose those types of putties that they can afford. There is a wide variety of them on the modern market.
When choosing, it is very important to pay attention to the following:
- Compound. Most cheap putties have an unpleasant composition. It can harm not the way the paint adheres to the surface of the gas tank, but also the health of the motorcyclist.
- Brand. It is best to give preference to products from trusted manufacturers.
- Volume. Each motorcyclist must determine exactly for what purpose he needs putty. Considering that it is not stored for a long time, it is better to correlate the size of the jar with the amount of work that needs to be done. Otherwise, you may end up overpaying for the volume, which over time will dry out in the garage and will not be suitable for further use.
- Purpose. It is important to pay attention to what surfaces the motorcycle putty is intended for.
Under no circumstances should putty be applied by hand. It is better to use a special tool for this purpose. With its help, the putty surface will be even and smooth. It will be possible to apply a layer of paint on it evenly.
The tank has a streamlined shape. That is why it is necessary to pay attention to the side areas when applying putty. Only if putty is applied correctly to them, the result will be of high quality and will delight any motorcyclist.
High voltage indicator
Rice. 5. High voltage indicator 1 - high voltage wire; 2 - glass tube; 3 - ends of wires; 4 - painted part of the tube.
Sometimes when tuning or repairing an engine, you need to know whether high voltage is being applied to the center electrode of the spark plug. For this purpose, either use various indicators, or, having disconnected the high voltage wire from the spark plug, bring it closer to the ground to make sure whether a spark jumps between the end of the wire and the ground. This check can be made easier. Cut the high voltage wire 5-6 centimeters from the spark plug, strip the ends and insert them into a glass tube 30-35 mm long so that there is a gap of 0.5 to 1.0 mm between them (Fig. 5). To observe the spark, paint the glass tube black, leaving a light strip 2-3 mm wide, through which the spark will be clearly visible. Wrap the connection points between the wire and the tube with insulating tape - this way the ends of the wire will be more securely fixed in the tube.

Stages of proper puttying of a motorcycle tank
Proper puttying of a motorcycle gas tank is carried out in several stages:
Important: Without degreasing, the putty will not lay down in an even layer, which will lead to cracks.
Thus, to give the tank of your motorcycle an aesthetic appearance, it is not at all necessary to go to motorcycle dealerships, where they charge a large amount of money for the work. At minimal cost, you can putty and make the surface of a motorcycle tank smooth and attractive in your garage, having everything you need at hand.
How to Use Putty to Level the Surface of a Motorcycle Gas Tank
Not many modern motorcyclists know how to properly putty a motorcycle tank. For many, this is a rather difficult process. Many people don’t even take up this task because they are afraid of cracks appearing on the surface of the motorcycle’s gas tank.
During work, you need to use putty correctly. Its main purpose is very often to be used for applying paint. It is used to level the surface. In order to hide all the irregularities or small dents, it can be applied in several layers. This must be done carefully using special tools for applying it.
The main task of puttying is to create an absolutely even layer on the surface of the gas tank. The main problem for applying putty is the shape of the motorcycle gas tank. Because of this, cracks may form on its surface, which may subsequently become an obstacle to the application of paint.
