Naraku CDI / ECU 18-Pin unrestricted for GY6 50 ccm 4-stroke Euro 4 with carburetor from model year 2018, OEM reference Rieju 0/005.705.3880 / Yamaha 5WX-H5540-00

The Naraku CDI is an unrestricted replacement ignition unit with an 18-pin connection for 50 ccm GY6 4-stroke scooters of the Euro 4 generation with carburetor from model year 2018. It corresponds structurally to the original ECU of these vehicles and, like the stock component, has no factory-installed RPM limiter. The OEM references enable comparison with the installed stock component.

Important Note:

• Suitable exclusively for Euro 4 models from model year 2018 with carburetor. Before purchase, it is mandatory to check the vehicle to see if an 18-pin ECU is installed.

Product Features:

• Replacement CDI / ECU without RPM limiter
• 18-pin connection (18-pin)
• For GY6 50 ccm 4-stroke Euro 4 engine with carburetor from model year 2018
• Corresponds to the construction of the original ECU
• OEM reference Rieju 0/005.705.3880 / Yamaha / MBK 5WX-H5540-00
• Note: For complete unrestricted performance of the scooter, further restrictors (e.g. on the variator) may need to be removed

The 18-pin connection and the restriction to Euro 4 carburetor models from model year 2018 are the decisive compatibility parameters - a mix-up with ECUs of other pin configurations or with Euro 3 predecessor models is not excluded for vehicles of this platform and will lead to a non-functioning ignition system. The OEM references Rieju 0/005.705.3880 and Yamaha / MBK 5WX-H5540-00 are the most reliable comparison parameters before purchase.
