Why Dirt Bike Engine Dies When Brakes Are Slammed? – Reasons And Their Solutions In 2023!

1. A Common Culprit When The Motor Dies With Hard Rear Braking And Clutch Is Low Idle RPM:

The first and most probable reason your engine dies when hitting the rear brakes is a low idling RPM. This means that the engine is running too slowly when you’re not giving it gas, which can lead to stalling.

• Solution:

To fix this issue, you can adjust the idle RPM. It’s a simple solution. Just increase the bike’s idle RPM by a couple of hundred revolutions per minute (RPMs). You can find the idle adjustment screw near the engine’s intake side. 

By making this adjustment, you’ll ensure that the engine doesn’t slow down too much when you’re not actively accelerating, preventing stalls and keeping your bike running smoothly.

2. Problem With The Fuel System Can Be A Possible Reason For Rear Brakes Locking:

Sometimes, if your dirt bike’s engine keeps stopping when you use the brakes, it could be because the fuel system isn’t working properly. 

This happens if things like the fuel filter or carburetor get all clogged up, making it hard for the fuel to go where it needs to. When that happens, the engine can stop running.

• Solution:

To resolve this, you need to make sure the fuel system is in good shape. It means checking and cleaning things like the fuel injector, fuel pump, fuel filter, and carburetor. 

When these parts are clean and working well, the engine will run smoothly, and you won’t have to worry about it stopping when you hit the brakes.

3. Dirt Bike Goes Off When The Brakes Or Stopping In Traffic Is Due To Clutch Issue:

In Addition, When your dirt bike unexpectedly goes off when you apply the brakes or come to a stop in traffic, one potential reason for this frustrating issue is related to your bike’s clutch.

• Solution: 

To rectify this problem, you should check your clutch. Make sure there isn’t too much free movement or play in the clutch lever. Having excessive free play can cause your engine to stall when you use the brakes. 

The solution is to perform a proper clutch adjustment, ensuring that your bike’s clutch operates smoothly. This adjustment will help you maintain control and prevent stalling, even during aggressive braking maneuvers.

4. At Last, Check Out The Carburetor Settings When Bike Stall During Hard Braking:

Finally, If your dirt bike engine dies when you use the rear brakes, one possible reason could be carburetor settings that need adjustment. 

The carburetor is a part of the engine that mixes air and fuel for combustion. When it’s not set correctly, it can lead to engine problems.

• Solution:

To repair this issue, you can make small adjustments to how the air and fuel are mixed. You might need to play with the pilot, air screw, and needle settings a bit to get it just right. Proper carburetor tuning can lead to smoother starts and prevent your engine from stalling when you use the rear brakes.

And that’s a wrap! By tackling these issues and applying the respective fixes, you’ll be on your way to a hassle-free dirt biking experience. Don’t forget to check out the Quora link I’m sharing, where you can gather valuable insights from fellow riders.

• Start With Position Your Foot: Keep your right foot on the footpeg, covering the rear brake pedal with the ball of your foot.

• Now, You Have To Apply Gentle Pressure: Gradually apply pressure to the rear brake pedal with your foot to slow down or control your speed.

• Next, Just Avoid Sudden Movements: Be smooth and progressive with your braking to prevent skidding or losing control of your bike.

• Furthermore, Balance and Control Are Important: Use the rear brake in combination with the front brake to maintain balance and control during braking.

Remember, proper rear brake usage is essential for controlling your dirt bike, especially in off-road conditions. You guys have taken a look at the YouTube video link For a user-friendly Guide!

Do All Bikes Die When You Brake? – Useful Information!

However, Not all bikes stall when you brake hard without using the clutch. However, most bikes with a clutch will stall if you lock up the rear wheel while braking. This happens because when the clutch is engaged, the wheel is directly linked to the engine. When the wheel stops, so does the motor. 

To prevent this, you can use the clutch to feather and control the braking force. This technique is particularly important on 2-stroke bikes like the YZ85  you’re considering, as it can help you maintain control during braking and acceleration.

Likewise, Dirt bikes, in particular, may stall when you brake due to their clutch system, but other regular motorcycles may not have this issue. So, it’s not a universal problem—each bike can behave differently. You can check out the further Forum-based Link For detailed answers on this!

Frequently Asked Questions:

1. Why Is My Motorcycle Dying When I Give It Throttle?

A clogged fuel filter or carburetor issue may be causing the throttle problem. Consider checking and cleaning these components for smoother throttle response.”

2. Can Brake Pad Wear Cause Engine Stalling?

Brake pad wear can lead to reduced braking efficiency but is unlikely to cause engine stalling directly. However, if the brake pads are severely worn, and the brakes are dragging excessively, it could indirectly affect the engine.

3. Why Does The Engine Stall Only When I Hit The Rear Brakes And Not The Front Brakes?

The rear brake is mechanically linked to the engine through the clutch. When you engage the rear brake, it can affect the engine’s RPM. Front brakes don’t have this direct connection, which is why you may not experience the same issue when using them.

4. Could An Electrical Problem Be Causing Engine Stalling When I Brake?

Yes, it’s possible. An electrical short or misconnection can disrupt the bike’s systems. Check the brake light wire for any shorts or misconnections, as this can cause a voltage drop that affects the engine’s performance.

Heading Towards The End:

In conclusion, engine stalls when hitting the rear brakes is a fixable issue. 

By adjusting your idle RPM, maintaining your fuel system, and ensuring your clutch is properly adjusted, you can enjoy a smoother and safer ride. 

Remember, regular maintenance and attention to detail are key to keeping your dirt bike in top shape. So, gear up, check this guide whenever needed, and ride on with confidence.
