Each type of restriction requires different modifications, and we will discuss these in detail throughout the article.

2. Safety Precautions

Before you start the derestriction process, it’s crucial to prioritize safety. Taking the necessary precautions will ensure that you perform the modifications correctly and protect yourself from potential risks. Here are some safety tips to keep in mind:

2.1 Gather the Right Tools

Having the correct tools for the job will make the derestriction process smoother and safer. Some common tools you may need include:

Socket and wrench set
Screwdrivers
Needle-nose pliers
Wire cutters/strippers
Shop rags
Safety glasses
Gloves

2.2 Protect Yourself

When working on your moped, it’s important to protect yourself from potential harm. Wear safety glasses and gloves to shield your eyes and hands from debris or accidental contact with sharp parts. Additionally, make sure you’re working in a well-ventilated area to avoid inhaling any fumes.

2.3 Consult a Professional

If you’re not confident in your mechanical ability or understanding of moped engines, it’s wise to seek assistance from a professional. They can guide you through the derestriction process and ensure that everything is done correctly.

3. Derestricting the Exhaust

One common restriction found in 50cc moped 4 strokes is the exhaust system. Manufacturers fit exhaust restrictors to comply with noise and emission regulations. Modifying the exhaust can result in improved performance and a deeper, more aggressive sound. Here’s how you can derestrict the exhaust:

3.1 Remove the Exhaust

Start by locating the bolts holding the exhaust to the engine. Use your socket set to loosen and remove these bolts. Gently slide the exhaust out of the mounting bracket, taking care not to damage any components.

3.2 Check for a Restrictor

Once you have removed the exhaust, inspect the inside for any restrictor components. Some manufacturers use washers or baffles to limit the exhaust flow. Remove these restrictors using pliers or a screwdriver, depending on their design.

3.3 Reinstall the Exhaust

After removing the restrictors, carefully reinstall the exhaust onto the mounting bracket. Ensure that it is securely fastened using the bolts you previously removed. Double-check that all connections are tight and aligned properly.

3.4 Test and Adjust

With the exhaust derestricted, take your moped for a test ride. Pay attention to any changes in acceleration or top speed. If necessary, make further adjustments to optimize your moped’s performance.

4. Derestricting the CDI

Another common restriction found in 50cc moped 4 strokes is the CDI (Capacitor Discharge Ignition) unit. The CDI controls the ignition timing and can limit the moped’s top speed. Here’s how you can derestrict the CDI:

4.1 Locate the CDI

The CDI is typically located near the battery or under the seat. Refer to your moped’s manual or consult online resources to find the exact location.

4.2 Remove the CDI

Use a screwdriver or socket set to remove the bolts securing the CDI to the moped. Carefully disconnect any wire connectors attached to the CDI, making note of their positions for reassembly.

Inspect the CDI for any visible modifications or markings that indicate restriction. Some restricted CDIs have a wire or connector that limits the ignition timing. Identify and remove any such components.

4.4 Reinstall the CDI

Once you have derestricted the CDI, reconnect the wire connectors and securely fasten the CDI to the moped using the previously removed bolts. Ensure all connections are tight and secure.

4.5 Test and Fine-Tune

Take your moped for a test ride to assess the impact of the CDI derestriction. Monitor the acceleration and top speed to determine if further adjustments are necessary. It may take some trial and error to find the optimal settings for your moped.

5. Derestricting the Carburetor

The carburetor is responsible for mixing fuel and air to create the ideal combustion ratio. Manufacturers often restrict the carburetor to limit the moped’s power. Derestricting the carburetor can improve acceleration and overall performance. Here’s how you can do it:

5.1 Locate the Carburetor

The carburetor is typically positioned on the side of the engine. Refer to your moped’s manual or online resources for guidance on finding the carburetor.

5.2 Remove the Carburetor

Use a socket set to loosen and remove the bolts securing the carburetor to the engine. Carefully disconnect any wire connectors or hoses attached to the carburetor.

5.3 Identify the Restrictor

Inspect the carburetor’s components for any restrictors. Manufacturers may install small inserts or washers within the carburetor to limit the fuel and air flow. Remove any restrictors you find using pliers or a screwdriver.

5.4 Reinstall the Carburetor

After derestricting the carburetor, reconnect any wire connectors or hoses. Securely fasten the carburetor to the engine using the previously removed bolts. Ensure all connections are tight and aligned correctly.

5.5 Test and Adjust

Take your moped for a test ride to assess the impact of the carburetor derestriction. Pay attention to the acceleration and overall performance. If needed, make additional adjustments to optimize your moped’s operation.

6. Derestricting the Intake

The intake system is responsible for delivering air to the engine for combustion. Some mopeds have intake restrictions that limit airflow, resulting in reduced power. Derestricting the intake system can enhance performance and throttle response. Here’s how you can do it:

6.1 Locate the Intake

The intake is usually positioned on the side or front of the engine. Consult your moped’s manual or online resources for guidance on finding the intake system.

6.2 Remove the Intake

Use a socket set to loosen and remove any bolts securing the intake system. Gently disconnect any hoses or wire connectors attached to the intake, remembering their positions for reassembly.

6.3 Identify and Remove Restrictors

Inspect the intake system for any restrictor components. Manufacturers may use inserts or baffles to limit airflow. Remove these restrictors using pliers or a screwdriver, depending on their design.

6.4 Reinstall the Intake

After removing the restrictors, reconnect any hoses or wire connectors to the intake system. Securely fasten the intake to the engine using the previously removed bolts. Double-check all connections for tightness.

6.5 Test and Optimize

Take your moped for a test ride to evaluate the impact of the intake derestriction. Notice any changes in acceleration and overall power. Fine-tune the intake system if necessary for optimal performance.

7. Maintenance Considerations

Once you have derestricted your 50cc moped 4 stroke, it’s important to keep up with regular maintenance to ensure longevity and continued performance. Here are a few maintenance considerations:

7.1 Spark Plug Inspection

Regularly inspect and clean the spark plug, ensuring it’s in good condition. Replace it if necessary, following the manufacturer’s recommendations.

7.2 Air Filter Maintenance

Clean or replace the air filter according to the manufacturer’s instructions. A clogged or dirty air filter can hinder airflow and performance.

7.3 Oil Changes

Frequent oil changes are essential for maintaining a healthy engine. Follow the recommended oil change intervals and use the appropriate oil for your moped.

7.4 Chain Lubrication

Keep the chain properly lubricated to prevent excessive wear. Regularly inspect the chain tension and adjust as needed.

Derestricting a 50cc moped 4 stroke can significantly enhance its performance, allowing you to experience improved acceleration and top speed. By understanding the different types of restrictions and following the steps outlined in this guide, you can successfully derestrict your moped and enjoy a more thrilling ride.
