Dirt bikes are renowned for their durability, often lasting years on end with proper care and maintenance.

Unlike standard motorcycles, dirt bikes endure harsh conditions such as mud, dirt, and rough terrain during their adventures. Therefore, neglecting to properly maintain and care for your dirt bike can significantly reduce its lifespan.

Routine maintenance for a dirt bike includes tasks such as regular washing, parts replacement, oil changes, visual inspections for damages, and monitoring tire pressure, among others. While professional maintenance services are available, many of these maintenance procedures can be performed by yourself with the appropriate tools and materials at hand. 

Taking the time to properly care for your dirt bike ensures its longevity and peak performance, allowing you to enjoy your time on the track or trails.

This article will outline a few of the necessary steps to take to properly care for your dirt bike.

Air Filter Cleaning

To maintain a healthy engine, it's crucial to consistently check your air filter. 

Just like a respiratory system, it ensures that only clean air enters the engine, optimizing combustion efficiency and ensuring smooth power delivery during the ride. 

Without proper maintenance over time, the filter can become clogged, reducing airflow and potentially causing decreased engine performance and reliability. 

Whether you're racing on a track or a trail, it's advisable to replace or clean your air filter after every ride.

 How to clean your Air Filter: 

    1. Remove the filter from the bike - Ensure that no debris or dirt falls into the airbox during the removal process.
    2. Apply cleaner - Next, you'll need to use a cleaner that effectively removes all dirt and debris without relying on petroleum-based chemicals. Maxima Oils offers a Foam and Fabric Air Filter Cleaner, which can be found here.
    3. Rinse - With the help of a faucet or garden hose, rinse the filter from the inside out, preventing the possibility of pushing dirt deeper into the filter fibers. Refrain from wringing or stretching the filter as it is prone to tearing easily. Rinse thoroughly until the water runs clear, and repeat the process if needed.
    4. Dry - Allow the filter to air dry prior to replacing or oiling (if required).
    5. If you have an oiled air filter: Once it is dry, evenly spray the necessary oil along the pleat crowns, then allow the oil to wick for 20 minutes. Squeeze out any excess oil before replacing the filter.

Tire Pressure & Spokes Check 

When it comes to dirt bikes, there are numerous components that are absolutely essential for proper performance and function, and tires are one of them.

Depending on the terrain, you'll need to adjust your PSI for optimal performance. When riding on a track or trail, a pressure of 12.5 psi is generally recommended and can be adjusted as needed. When riding on sandy terrain, it's recommended to decrease the PSI to 11 in the front and 11.5 in the rear. 

Regarding spoke inspection, it is important to check them on a regular basis, such as when you clean your bike. If any spokes look dented, twisted, or broken it is best that they are replaced immediately. 

Chain Replacement

No chain? No go. 

Whether your chain is impacted by damage, age, or wear, your bikes power will gradually depelte, ultimately leading to increased fuel consumption.

When does my chain need to be replaced?

  1. There's no chain tension
  2. The chain has rust
  3. The chain has visible kinks or is uneven
  4. The chain can be pulled away from the rear sproket
  5. The chain moves side to side

Nuts & Bolts Inspection

Nuts and bolts serve as the backbone of a dirt bike, holding its components together and preventing disassembly. Therefore, consistent inspection and fastening of these bolts are crucial, ideally after every ride or at least every 2.5 hours of operation.

Despite their small size, bolts play a significant role in ensuring both your safety and the proper functioning of your bike. Taking the time to thoroughly inspect and tighten everything regularly can make all the difference in your riding experience.

Engine Oil

To ensure your bike functions at its peak potential, it's important to maintain clean engine oil. Clean oil effectively lubricates the engine, preventing it from seizing or overheating.

We recommend checking your oil regularly, either after each ride or every 2.5 hours of use. It's advised to change your oil every other ride or every 10 hours, and sooner if necessary.


Let's talk carburetors. Luckily, carburetors are a component that is advised to be cleaned only once a year, or more frequently if you encounter performance issues.

Carburetors play a crucial role in blending fuel and air before delivering the mixture into the engine cylinders for combustion. Positioned on the engine block beneath the air filter, the carburetor operates through a blend of vacuum force and cable manipulation.

On that note, if your carburetor begins to fail, it can result in various issues. These may include difficulties starting the bike, poor engine performance, erratic stalling, and more.

How do I know when my carburetor is failing?

  • Black smoke from the exhaust: If you notice black smoke emanating from the exhaust of your dirt bike, it could be a sign of a failing carburetor. This smoke typically indicates an overly rich fuel mixture, suggesting that the carburetor is delivering too much fuel to the engine. Addressing this issue promptly by inspecting and potentially cleaning or adjusting the carburetor can help restore proper fuel-air mixture balance and engine performance.
  • Poor Engine Performance: Poor engine performance, such as sluggish acceleration or hesitation, often indicates carburetor problems. If you notice a decline in your dirt bike's performance, particularly during acceleration or under load, it's essential to inspect the carburetor for potential issues.
  • Idling Issues: Idling issues, like rough or erratic idling, can be a symptom of carburetor trouble on a dirt bike. A malfunctioning carburetor may struggle to maintain a consistent fuel-air mixture at idle, resulting in unstable engine operation. If you notice your dirt bike experiencing idling issues, it's crucial to inspect the carburetor for potential clogs, adjustments, or other issues to ensure smooth engine operation and optimal performance.
