NARAKU adjustable CDI unit NK390.23

The adjustable CDI unit is an essential component for optimizing the performance of your 50cc 4-stroke scooter. This device allows you to customize the engine ignition through a simple adjustment screw, which enables you to advance or delay the ignition depending on your needs. By turning it clockwise, the ignition is advanced, while turning it counterclockwise delays it, thus affecting acceleration and the overall operation of the engine.

The CDI unit is particularly useful for tuned vehicles, as it allows you to adapt performance to specific riding requirements. Upon delivery, the adjustment screw is in the central position, allowing for a wide range of adjustments: approximately 12-13 complete turns in both directions. The stop mechanism is designed to provide tactile feedback, ensuring precise adjustment.

It is important to consider the type of voltage of your scooter, which can be AC or DC. Scooters with AC voltage can start without a battery, while those with DC voltage require a battery for ignition. Incorrect installation of the CDI unit could cause damage to the vehicle's main fuse, but it will not compromise the CDI unit itself. With this adjustable CDI unit, you have the opportunity to enhance the efficiency and performance of your scooter, making every ride a more exciting experience.
