What is Derestricting?

Derestricting is removing part of the circuitry in a 50cc scooter that prevents it from reaching its maximum speed. Once restricted, your scooter will be able to reach speeds up to 70km/hr. Scooters come from the factory with two main restrictions: small jets and a circuit board limiting reach its maximum speed. A user must purchase larger jets or obliterate the circuit board to get a scooter to reach its top speed.

The circuit boards are soldered in, so removing them is not possible. Removing jets from a scooter is sometimes more difficult than other models, depending on the model-specific features of the jet. Removing the scooter. Once the jets are removed, the entire fuel system must be checked and re-adjusted to keep your engine from running lean or flooding.

Why is Derestricting in Scooter Important?

A scooter modified to reach its full potential is more enjoyable to drive. It reaches the speeds people are used to and makes for a better experience on longer commutes. It is also much faster than other 50cc scooters. Note that derestricted or high-speed scooters are not street legal in any area that requires a driver to have a driver’s license for operation. It is illegal to ride this scooter on public roads.

The scooter owner will be responsible for any fines incurred while operating on public streets. Don’t forget that some states require special licensing to operate a scooter over 50cc. Some areas are more restrictive than others, so it is important to understand your local laws before modifying your scooter in this way!

Derestricting Procedure for the Taotao 50cc Scooter:

1. Ensure to do this at your own risk; if you are not comfortable doing it, don’t try it or ask anyone (such as a professional) to do it.

2. Disconnect the negative side of the battery and wait at least 5 minutes before starting this process.

3. Take off the black cover on top of the engine and remove the spark plug using a wrench (make sure to wear safety goggles/glasses).

4. Hold down the throttle and brake levers tightly, start up your scooter and leave it idle until you see that it is about to stall (the RPM indicator will be at the maximum).

5. Remove the air cleaner by undoing two screws on top of your carburetor using a wrench, then take it off slowly.

6. Using a small screwdriver, open up the fuel mixture screw located on your carburetor clockwise until it is almost running for about 30 seconds.

7. Stop the engine, disconnect the spark plug, put back on the black cover, and reconnect the battery’s negative side.

How to Derestrict a Taotao 50cc Scooter: 10 Ways to Smooth And Effective Scooter Derestricting

1. Variator System:

On your scooter’s variator system, the variable pulley screw of the drive belt is where you’ll find your jets. Unfortunately, the two different sizes of screw holes ensure that only one size jet can be used at a time. Hence, it is essential to keep track of which screws go into which hole and how they should be installed, or else the function and performance of your scooter may be compromised.

2. Get Rid of the Kickstart:

The kickstart is another important part of the 50cc scooter that restricts its top speed. The kickstart wire enters your scooter’s ignition coil, making it impossible to reach speeds greater than 30mph. The easiest solution for this problem is using an alternative power source such as a battery or DC adapter when riding your scooter.

3. Swap Jet Sizes:

This method requires extra parts and time, but the payoff will be well worth it. Instead of removing jets from your carburetor, swap them with one another so that no single jet has full control over the flow rate in your engine. For example, if there are two identical jets in your scooter – both size 47mm and one of them is restricting your scooter’s speed, you can remove the smaller jet and replace it with a larger one.

4. Use An Air Filter:

This method involves buying an aftermarket air filter and replacing your current air intake system. The easiest way to do this is by using a cone-shaped foam air filter that allows airflow into your engine but restricts dirt particles from entering. While this modification does not increase the top speed of your scooter, it will allow you to achieve speeds of up to 70km/hr without having to purchase any additional components for your scooter, such as jets or carburetor kits.

5. Make Sure You’re Using High-Quality Fuel:

Next time you fill your scooter up with gasoline, make sure you’re using a high-quality brand. Generic fuel is usually cut with corn alcohol or kerosene, which can reduce your engine’s “octane” level and lead to decreased speeds.

6. Remove Your Exhaust Pipes:

If you need to remove all restrictions from your scooter to achieve top speeds over 70km/h, consider removing the exhaust pipe instead. Simply detach both pipes from their mounting points under your scooter’s hood and remove them from the vehicle completely. This will increase airflow into your engine and allow it to run at its full potential capacity while idling and accelerating.

7. Use a Riser:

Some scooter riders prefer to use aluminum bar risers that increase airflow into the carburetor, increasing speeds and acceleration slightly. These risers can be attached under your scooter’s handlebars by bolting them to each side’s existing mounting points. Just make sure you don’t attach them too high, or you’ll tie up the throttle, causing unwanted acceleration.

8. Exchange Intake Manifold:

Another option for scooter riders is to purchase an aftermarket intake manifold that increases airflow from your carburetor into your engine. These manifolds are also fitted with velocity stacks that allow air to enter your engine more rapidly, increasing your scooter’s top speed.

9. Get Rid of the Muffler:

Removing the muffler on your scooter is another way to increase its speeds slightly by allowing air to escape from the engine more quickly. However, this also requires removing the exhaust pipe if you have one installed, which can be difficult for some riders to perform independently. For this reason, it may be advisable to take your scooter into a shop and have a mechanic or experienced technician remove these parts for you to enjoy increased speeds with no additional work required from yourself.

10. Remove Washer Around Front Pulley Rod:

When you remove the washer located around your scooter’s front pulley rod, it will cause your throttle to open up all the way, allowing you to maintain a constant speed when traveling at lower speeds.

Removing this particular washer will make your scooter run much more efficiently and increase speeds slightly due to improved airflow. However, this will also make your engine very loud when traveling at high speeds. Overall, it’s a pretty simple and inexpensive way to increase the speed of your scooter without having to spend money on new components or kits.

Why Are Scooter Engines Restricted?

A 50cc scooter engine is restricted for several reasons. First, scooters are designed to be ridden by people with minimal training. This means that they are built to have very predictable characteristics, and their engines are not allowed to be modified in any way that might change these characteristics or make them unsafe.

Scooters are typically used as a mode of transportation by commuters looking to save money, and the people who own them don’t want to pay a bunch of extra cash for a vehicle that can go dangerously fast. Their reduced speed also helps them from being as intimidating as motorcycles or other larger vehicles on the road.

You might want to remove some restrictions from your scooter engine, but safety should always be your number one priority. So if you are interested in how to derestrict a taotao 50cc scooter be sure to read this full article.
