Honda is a famous and reliable manufacturer of vehicles, including ATVs. One of the most popular ATVs from Honda is called the Honda 400EX. This ATV has been around for decades and is still one of the most favorites for the ATV enthusiast because of its reliability. If you are planning or have just bought your Honda 400EX, here’s how to do basic maintenance of the vehicle.
Routine Maintenance Schedule
For your engine oil, you should replace it once every 2000 km or 200 hours of usage, whichever comes first. It is also important to do a regular check every 150 km or 20 hours of usage. If you are a cautious person, you can schedule your regular oil change every 1000 km or 100 hours of usage.
The same schedule applies to air cleaners; you should clean them once every 2000 km or 200 hours, but it would be better if you do it every 1000 km or 100 hours. For valve clearance, you need to get it inspected every 2000 km or 200 hours, whichever comes first.
Do-it-yourself Maintenance Guide
The first thing you could do is always keep your ATV clean. Make sure that you clean it thoroughly after every ride, especially the rough ones. Clean it after rides before the dirt and mud hardened. It would be difficult to clean, and it could lead to fatal problems.
Changing oil regularly is crucial for any vehicle, including an ATV. To check your oil, do it after you start the engine, allowing oil to circulate thoroughly through the engine. You can start the engine and then let it idle for around 5 minutes. After that, remove the oil filter cap from the oil tank and clean it.

Troubleshooting and Winterization
The main common trouble with this vehicle is that it won’t start, and there are several things you could try to fix. You could try to test the battery voltage, test the main fuse, and then test the starter and solenoid motor.
Next is about how to get your Honda 400EX ready to face the winter. You need to wash it with soap and water thoroughly, fill the gas tank completely or completely drain it and then don’t forget to change the oil. Next, you should connect a battery tender and then leave it attached.
TL;DR:
Regular oil changes: Engine oil lubricates moving parts, reduces friction, and carries away heat. Fresh oil is vital for keeping your ATV running smoothly and preventing engine wear. The guide recommends changing it every 2000 km or 200 hours, whichever comes first. More frequent changes are recommended for cautious users or after riding in dusty or dirty conditions, as contaminants in the oil can accelerate wear and tear.
Air filter cleaning: A clean air filter ensures clean air enters your engine, allowing for proper combustion and optimal engine performance. A clogged air filter restricts airflow, reducing power and fuel efficiency. The recommended cleaning schedule is similar to oil changes, every 2000 km or 200 hours. More frequent cleaning might be needed in dusty conditions or after every ride in particularly dusty environments.
Valve clearance inspection: Valves control the intake and exhaust of air and fuel in the engine. Proper valve clearance is essential for efficient engine operation. Valves that are too tight or too loose can affect engine performance and fuel economy and even lead to engine damage. The guide suggests getting them inspected every 2000 km or 200 hours.
Thorough cleaning: Regularly clean your ATV, especially after rides, and remove dirt, mud, and debris that can accumulate and cause problems later. Dirt and grime can clog vents, filters, and other components, leading to overheating, performance issues, and premature wear. Pay particular attention to areas around the engine, drivetrain, and wheels.
Winterization preparation: Before storing your ATV for winter, take steps to protect it from the elements and prevent damage during cold weather. Wash it thoroughly to remove dirt, salt, and other contaminants that can cause corrosion. Address the gas tank by either filling it with fresh fuel and a fuel stabilizer to prevent moisture buildup or emptying it. Change the oil to remove contaminants and use oil with a viscosity appropriate for colder temperatures. Finally, a battery tender must be connected to maintain the battery charge and prevent it from dying during storage.
Additional Tips:
- Consult your owner’s manual for specific maintenance intervals and procedures for your Honda 400EX model year.
- If you need more time to perform certain maintenance tasks, consider taking your ATV to a qualified mechanic.
- Keep a maintenance log to track what services have been performed and when.
By following these tips, you can help ensure your Honda 400EX ATV runs smoothly and reliably for many years to come.
