Tips for Motorcycle Maintenance Learn a Little Bit Every Day and You Will Become a Maintenance Expert Sooner or Later

1. Cylinder Scratching Treatment

Mix a small amount of epoxy glue and gently apply it along the cylinder bore scratches to fill them. Let it sit for about 20 minutes, then sprinkle a light layer of talcum powder on it. Press it down gently, then scrape it with cardboard to create an arc that matches the cylinder bore. Let it sit for another 4-6 hours. This method is only suitable for minor scratches. For more severe scratches, it's best to replace the cylinder head.

2. Quickly Clean Cylinder Carbon Deposits

Unscrew the spark plug and spray a few times of carburetor cleaner into the cylinder through the spark plug hole. Then tighten the spark plug, turn on the ignition, and leave the engine running for a few minutes. This method is only suitable for loose carbon deposits. For older deposits, forget about it. Minor carbon deposits can sometimes be removed by driving on a straight, high-speed road. 3. Cleverly Removing the Cylinder Head

If your motorcycle's cylinder head is too tight, first remove the fixing screws. Then drip a few drops of gasoline into the cylinder through the spark plug hole. Reinstall the spark plug. Then, tie the cylinder block and cylinder head tightly with a rope. Turn on the ignition and firmly press the starter lever. When you hear the engine crackle, you can easily remove the cylinder head.

4. Removing Rust from the Fuel Tank

Use a small, slightly flexible stick, about 30 cm long, with a magnet attached to one end. Insert it into the bottom of the fuel tank and rub it back and forth. After rubbing for a while, remove the rust that has attracted to the magnet. Repeat this several times. You can also fill the fuel tank with water and some small stones and shake it repeatedly for a while to remove the rust.

5. Restoring the Fuel Tank

If the fuel tank is dented, first clean it out. Then, fill it three-quarters full with soybeans and top it off with water. Tighten the cap. It's important to pour out the soybeans immediately after the dent has healed. If you delay, they may not come out.

6. Rust Removal of Electroplated Parts

Get some ammonium acetate, add it to an equal amount of water, and heat it to 70°C. Then, saturate a soft cloth with it and scrub the rusted area. Once the rust is completely gone, wipe it dry with a dry cloth.

7. Tips for Cleaning a Motorcycle Carburetor

During use, mud and water often accumulate at the bottom of a motorcycle carburetor, affecting proper driving. Here's a clever way to clean it without disassembling the carburetor: First, turn off the fuel tap. Use a screwdriver to loosen the drain screw at the bottom of the carburetor. Drain all the fuel from the carburetor. Then, turn on the fuel tap. Once the fuel begins to flow, blow air (or use an air pump) continuously into the waste oil pipe on the outer wall of the throttle valve. Mud, sand, and water droplets will spray out of the drain pipe at the bottom of the carburetor. Repeat this several times to clean the sediment and water in the carburetor float. Then tighten the bottom screws and the motorcycle can be used normally.
