Product Information

Full details

The Naraku CDI Unrestricted Ignition Unit (700.05.57) is designed for owners of 2-stroke scooters from brands like CPI, Keeway, Longjia, and Generic who want to unlock the full performance potential of their engine. By removing the factory-imposed electronic RPM limiter, this unit is an essential upgrade for those who have installed 70cc cylinder kits or other performance modifications. While it offers a significant boost in performance, it is important to note that this unit is exclusively compatible with engines utilizing a double-plug CDI system and will not work on cable-based ignition setups.

Extended Product Information

FAQs

Will this CDI increase my top speed?

By removing the electronic RPM limiter, it allows the engine to rev higher, which often results in an increase in top speed, provided the engine has sufficient power to pull the gearing.

Is this legal for road use?

This component is designed for performance and racing applications. Please check your local traffic regulations regarding modifications to vehicle speed limiters.

How do I know if my scooter has a double-plug CDI?

Physically inspect the existing CDI unit mounted on your scooter frame. If it features two distinct electrical plug connections, it is a double-plug system.

Does this work on 4-stroke engines?

No, this specific unit is engineered exclusively for 2-stroke engines.

Do I need to tune my carburetor after installation?

While not always mandatory, it is highly recommended to check your spark plug color and carburetor jetting, as the engine will be operating in a different RPM range than before.

Troubleshooting

Engine does not start after installation

Double-check that both plugs are firmly seated and that you have verified your vehicle uses a double-plug system rather than a cable-based system.

Engine still feels restricted at high RPM

Verify that your carburetor jetting and transmission weights are properly tuned to match the higher RPM range unlocked by the CDI.

Pros and Cons

Pros

  • Removes speed and RPM restrictions for better performance
  • Easy plug-and-play installation process
  • Ideal for tuned 70cc engine setups
  • Reliable replacement for restrictive factory units

Cons

  • Not compatible with cable-based ignition systems
  • Requires verification of double-plug configuration before purchase
  • May require additional tuning of carburetion depending on engine modifications

Setup, Compatibility & Care

Installation is designed to be straightforward. Locate your original CDI unit, disconnect the double-plug harness, and swap it with the Naraku unit.

Compatibility Requirements:

  • Ensure your vehicle utilizes a double-plug CDI plug system.
  • Confirm the manufacturer is CPI, Keeway, Longjia, or Generic.
  • Do not attempt to install if your vehicle uses a cable-based ignition system, as it will not fit.

Care Instructions: Ensure all electrical connections are clean and free of moisture or corrosion during installation to prevent signal interference. Regularly check that the unit remains securely mounted to prevent vibration damage.
