Fitment FAQ
Will this part fit my specific model and year?
This fuel injection kit is intended for Vehicle Type; Brand / Model; Engine. Key physical/spec details from the product data include 169cc, 170cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. If your original part has a stamped OEM or manufacturer number, match that number first before ordering. For this fuel injection kit, also compare the ECU/EFI compatibility, injector plug type, throttle body size, sensor connectors, harness layout, and engine displacement. This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this fuel injection kit for machines outside the listed compatibility, or for units with different ECU systems, injector connectors, sensor plugs, throttle-body sizes, or harness layouts. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the ECU/EFI compatibility, injector plug type, throttle body size, sensor connectors, harness layout, and engine displacement. Recheck listed specs such as 169cc, 170cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
It was all good until it came to installing the fuel pump which was too tall other than that it was a good product
Después de que mi scooter empezara a ratear, le metí este pack completo y volvió a rugir como nuevo. Trae de todo: ECU, bobina, sensor de O₂, relé de la bomba, cuerpo de acelerador con inyector… todo embolsado y etiquetado, así que sólo fue desconectar el viejo cableado y enchufar el nuevo. Los conectores cuadran al milímetro y arrancó a la primera sin petardeos ni pérdidas de potencia, incluso dándole caña en cuestas.
Puntos a tener en cuenta: el cable del sensor de temperatura llega algo justo y, para rematar, no viene ni un triste manual en papel—tocó tirar de un vídeo en el móvil para no liarme con la ECU. Quitando eso, instalación plug-and-play y motor funcionando más fino que nunca.
Installed this EFI kit on a 170cc GY6 engine and it worked great right out of the box. Everything was included and labeled well, which made the process way smoother than I expected. If you’ve got some experience working on engines, setup should be pretty straightforward. The bike starts quicker now and runs a lot smoother, especially at idle and lower speeds. Throttle response feels more consistent too. Haven’t had any fuel issues since swapping over. It’s a solid upgrade if you’re looking to ditch the carb and get more reliable performance without constant tuning.
If you have a scooter or something with a GY6 engine and you need to repair or replace the EFI system, this has it all, from the O2 sensor to the fuel pump to the throttle body. It's a very inclusive package. All the parts seem to be decent quality, and I have no complaints about any of it. 5 stars.
