Changing the engine oil in your motorcycle is an important maintenance task that can help extend the life of your engine and ensure that it runs smoothly. In this guide, we’ll walk you through the steps of how to change the engine oil in a small motorcycle.
Before starting the oil change, it’s important to make sure you have all the necessary tools and supplies. This includes a new oil filter (if applicable), a container to catch the old oil, a funnel, a socket wrench or pliers, and a screwdriver. You’ll also need to purchase the correct type and amount of oil for your motorcycle.
An Engine Oil Change Guide for Small Motorcycles
Step 1: Locate the oil drain plug
The first step in changing the engine oil is to locate the oil drain plug. This is typically located at the bottom of the engine, but the exact location can vary depending on the make and model of your motorcycle. Additionally, the size of the plug may be different from one motorcycle to another. It’s important to use the correct size wrench to avoid damaging the plug or the engine thread.

Step 2: Place the motorcycle on a flat surface
Next, place your motorcycle on a flat surface, such as a garage floor or driveway. If your motorcycle has a center stand or a side stand, use it to support the motorcycle in an upright position.
Step 3: Open the oil cap
Locate the oil cap, also known as the dipstick, on the top of the engine. The oil cap is usually located on the right side of the engine. Using pliers or a screwdriver, gently loosen the cap. The main reason for doing this is to allow air to flow into the engine, which will make it easier for the oil to drain out later.

Step 4: Place the container under the oil drain plug
Position a container under the oil drain plug to catch the old oil as it drains out. Make sure the container is large enough to hold all the oil, and use a socket wrench or pliers to remove the drain plug. The direction in which you need to turn the plug to remove it can vary depending on the make and model of your motorcycle. For some Japanese motorcycles, mostly the plug needs to be turned counterclockwise
Step 5: Drain the oil
Once the plug has been removed, the old oil will start to drain out. Allow the oil to drain for a few minutes until it stops dripping. If it takes longer than a few minutes for the oil to stop dripping, you may need to check for any blockages or debris that could be preventing the oil from draining out completely,

Step 6: Check the sealing washer
After the oil has finished draining, inspect the sealing washer on the bolt. If it is damaged or worn, replace it with a new one.
Step 7: Reinstall the plug
Insert the bolt back into the hole by hand, and then use a socket wrench to tighten it in place. Be careful not to overtighten the plug, as this can cause the thread to loosen.

Step 8: Fill the engine with new oil
Using a funnel, pour the correct amount of new oil into the engine. Consult your motorcycle’s owner’s manual or the manufacturer’s recommendations to determine the correct amount of oil to use, or check the level.
How much does to fill the engine oil? make sure it is below the max level or upper than min level, 800ml or 1 liter depending on the motorcycle’s manufacturer.
Step 9: Check the oil level
After filling the engine with new oil, close the oil cap and start the engine. Let the engine run for a few minutes, then turn it off and check the oil level using the dipstick. If the oil level is low, add more oil until it
reaches the maximum level indicated on the dipstick. If your motorcycle does not have a dipstick, there may be a small screen on the engine or an indicator light on the dashboard that shows the oil level.
Step 10: Dispose of the old oil properly
After you’ve finished changing the oil, it’s important to dispose of the old oil properly. Most service stations and auto parts stores will accept used motor oil for recycling. Follow your local regulations for disposing of hazardous materials, and never pour used motor oil down the drain or on the ground.
Oil change interval for small motorcycles below 125cc
It’s important to change the engine oil in your small motorcycle at regular intervals to ensure that it remains in good working condition. As a mechanic, I recommend changing the oil after the first 1000 km, or after you’ve reached 2000 km or 3000 km if you’re using high-quality engine oil. However, it’s generally a good idea to change the oil earlier rather than later to ensure that your motorcycle is always performing at its best. Regular oil changes can help extend the life of your engine and keep it running smoothly.
By following these steps, you can change the engine oil in your small motorcycle yourself, saving time and money on labor costs. Remember to always use the correct tools, supplies, and oil for your specific motorcycle, and follow the manufacturer’s recommendations for oil changes. Regular oil changes are an important part of maintaining your motorcycle and can help ensure that it runs smoothly and efficiently.
