However, I can assure you that you will not have any confusion with dirt bike gas after finishing my whole article. Hence, don’t run anywhere without finishing the article from top to bottom. Here, every word will be vital for you.

So, let’s start your reading:

Are Dirt Bikes Good On Gas?

Dirt bikes generally come with 2-stroke and 4-stroke engines. And both the engines are running very well on gas. In fact, both engines are capable of providing you the best possible performance if you use a premium dirt bike gas. 

You can read my previously written article ‘Do Dirt Bike Run On Gas?’ to know more about the connection between the gas and the dirt bike.

What Kind Of Gas Does A Dirt Bike Take?

I often hear this question from dirt bike riders, especially those who are new. You’ve used such gas for your dirt bike, which is recommended by the owner’s manuals.

According to my experience, you should use a regular 87 octane pump dirt bike gas for the fuel-injected 4-stroke engines. In the case of 2-stroke engines, ethanol-free 92 or 93 octanes could be the best choice. 

Don’t use such dirt bike gas, which has more than 10% ethanol. However, to get the best experience, always use premium quality dirt bike gas instead of regular gas. Click the link to learn the differences between the premium dirt bike gas and the regular dirt bike gas.  

How To Check The Gas Condition Of Your Dirt Bike? (3 Tests)

Before draining, you’ve to check the gas condition of your dirt bike. By following my methods, you can easily understand whether the gas is alright to continue or need to be changed. 

Do the following 3 tests to check the gas condition of any dirt bike:

Test- 1: How Is Your Dirt Bike Running?

It is the most straightforward test to understand the gas condition of a dirt bike. In this test, you just need to observe how your dirt bike is running. If your dirt bike is running poorly or takes too much time to start, you’ve to change its gas. Because these are the possible symptoms of bad gas.

Test- 2: How Does Your Dirt Bike Gas Smell?

A smell test will help you to know the gas condition of your dirt bike. When you get sour or stale smells from the dirt bike gas, that means the gas has probably gone bad. Just keep in mind that you’ll never get the original scent from bad gas. Even an untrained nose can understand the condition by testing the smell of gas.

Test- 3: What Does The Color Of Your Dirt Bike Gas Look Like?

You also can understand the gas condition by checking its appearance and color. When the clean and clear appearance gas turned into a darker color, that means it went bad. Hence, before pouring the gas into the tank, take a sample because it’ll help you identify the differences in gas color and appearance.

You can do all 3 tests together to check the gas condition. If you find or suspect anything wrong, don’t delay draining the gas from your dirt bike. In the next subhead of my article, you’ll learn how to drain them in detail.

How To Drain The Gas From Your Dirt Bike?(4 Steps)

Step- 1: Tools You Needed:

Here, I have listed the tools that you need to drain the gas from your dirt bike:

  • A Screwdriver.
  • A Shop Rag.
  • An Empty Bucket.

Gather all the necessary tools before moving to the further steps.

Step- 2: Select A Wide Space:

In a narrow space, you may face many difficulties in completing this task. So, you require a wide and well-ventilated space to drain the gas. Driveway is the most suitable place to do the job. Before moving to the next step, make sure that your fuel valve is ‘off.’

Step- 3: Unscrew The Securing Clamp:

You’ve to chase the fuel hose from the lower part of the tank to the carburetor. Then use your screwdriver to unscrew the securing clamp that holds the hose of the carburetor. After that, position a shop rag in the region of the end and tug it off the carburetor spigot.

Step- 4: Let The Gas Drain Out:

Place an empty bucket under the fuel tank. Then turn the dirt bike fuel valve ‘on.’  With that, the fuel flow from your gas tank will be started. Thus the bad gas will directly fall onto your placed bucket. And then wait until the gas drains out completely.

When the exhaust is appropriately finished, install the parts you opened. That’s it, we’re done.

How To Mix Gas For A 2-Stroke Dirt Bike? (3 Steps)

When you know the exact and most accurate fuel ratios, it’s not too difficult to mix gas for a 2-stroke dirt bike. Just follow these simple steps to do that comfortably:

Require Ingredients:

  • Dirt Bike Gas,
  • Container,
  • Dirt Bike Oil Can,
  • Measuring Cup,
  • Owner’s Manuals,
  • Internet.

Gathers all the required ingredients, and then move into the practical 3 steps to mix gas for your 2-stroke dirt bike:

Step-1: Choose The Gas And Oil:

Step-2: Premix Ratios:

You get the information about gas and oil ratios in your owner’s manuals. If you lose it, there is nothing to worry about. Just do a quick research on google by searching your specific dirt bike model that requires fuel ratios.

By the way, you can follow my providing fuel ratios chart too.

Step-3: Mix The Oil And Gas:

I wouldn’t recommend mixing gas directly into the tank of your dirt bike. Pour the oil into the gas container according to your 2-stroke dirt bike’s required fuel ratios. In my case, I used a 32:1 fuel ratio for my 2-stroke dirt bike. That means, I need 16 ounces for 4 gallons. 

Anyway, make sure that you use a measuring cup to keep the gas and oil mixing proportion accurate. Then shake the mixture properly to get a better result. And finish your job by fueling up your 2-stroke dirt bike. 

That’s it, now you’re all set for a new dirt bike ride.

8 Tips To Maintain Your Gas Dirt Bike:

At the beginning of my article, I promised you that I would share my personal tips with you. Here are my 8 tips that I personally follow to maintain my gas dirt bike, and I’m very sure that it will be helpful for you too:

Tip- 1: Find And Fixed The Leak:

Any leaking of your gas dirt bike can cause serious accidents. That’s why you’ve to be careful and should regularly check the leaks of brakes, coolant/gas chambers, and oil. Take a proper step as soon as possible when you find any leaks in any spots of your gas dirt bike.

As a responsible rider, you should always check leaks in your gas dirt bike before you go on a ride and after you get back from it. Never overlook the leaking issues, especially when you’re the owner of a gas dirt bike.

There is no alternative but regular maintenance to increase the lifespan of a gas dirt bike. In the same way, it’s also equally important to do the maintenance in the right way.

That’s why you’ve to be focused on the proper washing and drying of your gas dirt bike. It is ideal for washing your gas dirt bike after each ride because it prevents the dirt and dust layer and keeps the color in good shape for more extended periods. 

During washing, make sure that you cover the sensitive parts of your gas dirt bike engine by using masking tapes or plastic bags. It is because water can seriously damage several parts of the engine. After that, wait until your gas dirt bike dries properly. Avoid checking any hardware issues in that period.

Tip- 3: Change Your Gas Dirt Bike Oil:

I often say that oil is like food for your gas dirt bike. It provides the energy to the engine for running faster. So, it’s very important to change the oil of gas dirt bikes on a regular basis to get the best service.

Use a quality brand gas dirt bike’s oil and change it 8 to 10 hours after your every ride. And also, make sure that you mix the appropriate ratio of gas and oil. 

Tip- 4: Grease Your Dirt Bike Engine:

The engine determines the performance of your gas dirt bike. But when it’s come to the touch of dirt or water, then the performance capability and the quality both go down. That’s why you’ve to grease your dirt bike engine regularly to prevent the entering of dust and water.

Tip- 5: Extra Care To The Air Filter:

Air filters work as a safeguard of your gas dirt bike engine. Dust can’t enter the engine because of the protection of the air filter. As a result, your gas dirt bike’s air filter becomes dirty after a few rides. However, by proper maintenance, you can improve the capabilities and the lifespan of your gas dirt bike’s air filter. 

Tip- 6: Lubricate The Chain:

During the ride, the chain comes in direct contact with the road dust. In consequence, the chain of your gas dirt bike becomes dirty after every ride. And after a few rides, you’ll feel that the chain is not smooth enough to run faster. It is because of the accumulated dirt.

That’s why I suggest you lubricate your gas dirt bike’s chain after every 3-4 rides. And, don’t forget to inspect every area of your gas dirt bike chain thoroughly every time after getting back from a ride.

Tip- 7: Always Checking The Vulnerable Parts:

Basically, a few parts of a gas dirt bike can be vulnerable at any time. Bolts, throttle, cables, tires are the main victim of getting vulnerable. You’ve to be extra careful about these parts. Check them regularly to avoid any type of hap. Proper tightening and lubricant are effective ways to fix the vulnerable parts of your gas dirt bike.

Tip- 8: Consult With A Mechanic:

Literally, it’s not possible to solve all gas dirt bike-related issues by yourself at home. And there are also such types of issues that are not possible to identify by the person who is not a professional mechanic.

It is wise to consult with a professional mechanic at least twice a year in these circumstances. Do that even if everything on your gas dirt bike is alright. And it’s needless to say, visit a professional mechanic without any delay when you find something wrong with your gas dirt bike.
