  • Aircraft remover.
  • Soft towel.
  • Wired brush.
  • Rotary tools.
  • Send paper.
  • Spray paint.

Step 1: Disassembling

Disassemble the engine from your motorcycle with the toolkit box. After disassembling the engine, remove all the parts. To get the perfect color to each edge of your engine, and that looks great, you should do the process.

Step 2: Cleaning

Cleaning the motorcycle engine is a vital factor before you go for painting. If you have an old bike with a miserable condition, then you find old damaged color on the engine with rust. 

Then you need to clean the old half faded color. To remove the old discoloration and rust, you need to use aircraft remover. Coated the engine with aircraft remover and wait for 30 minutes and then use sandpaper to remove the old color and rust after that use a soft towel to make the engine clean and bright. 

Before doing the process, don’t forget to cover the spark plug port and the oil line and other circuits of the engine with mask tape.

Step 3: Polishing

Polishing is essential to grab the color on the engine surface. To polish the engine surface, you can use sandpaper. After the cleaning stage, you have to rub with sandpaper to make the surface smooth. Otherwise, the color is not correctly set. 

On the other hand, if you find any rough area on the engine body, you need to rub that place to make that edge smooth compared to the other side. The key point is ‘polished the surface accourting to the surface roughness.

Step 4: Painting

Painting is the central part of all the steps. But before starting painting, check again the plugs, spark plug, and all the wire connections covered with mask tape. After making that okay, you can begin painting. But for that, you have to choose a color. My recommendation is to use spray paint. Here you can use Dupli-color, Rust-Oleum, Bright-Touch. All the colors are okay with the quality, durability, and temperature resistivity. After choosing your preferred color, make at least 2-3 layers on the engine. Otherwise, the color may fade after one or two months. If you can go for more layers, that is perfect for you. After completing the painting, you have to wait until the color dried.

Step 5: Assembling

After finishing the painting, you have to assemble the parts on the body of the engine. Remove the masking tape that you have set on that before. Set the spark plug, join the wire plugs and assemble the whole engine on your motorcycle.

Safety Precautions

  • Use safety goggles and hand gloves when you clean the engine.
  • Use a mask when you are painting the engine with spray paint.
  • Always be careful about the points where the painting is forbidden (Spark plug port, wire port).
  • Put on a mechanical apron while doing the whole process.


Painting on the motorcycle engine is vital to protect your engine surface from getting rust and damaged. If you are a motorcyclist and like to design your bike with your way, then engine painting is also a part of developing your motorbike. Select your preferred color. The mat black is always on the top of the choice for most of the bikers.
