MOREV 9-Curve Backfire CDI – 5-Pin AC
The MOREV Digital Adjustable Backfire CDI offers nine selectable ignition settings for backfire effects. This version is intended for selected 50cc–125cc four-stroke horizontal-engine motorcycles, pit bikes, ATVs and other applications equipped with a compatible 5-pin AC CDI ignition system. It is a separate product from the MOREV 9-Curve Non-Backfire series.
Important: Modified Exhaust Required
A suitably modified exhaust system is required to achieve the intended backfire effect. Installing this CDI alone will not create the intended backfire effect. Actual results depend on engine condition, exhaust design and overall vehicle setup; exhaust popping or visible flames are not guaranteed. Exhaust changes may be subject to local noise, emissions and road-use regulations.
Key Features
- Nine backfire settings: Select from curves 1–9; there is no 0 setting.
- One-button adjustment: Select a setting using the built-in button, before or after engine startup.
- Digital display: Shows the selected setting.
- 5-pin AC configuration: Designed for the matching AC-powered CDI ignition system and connector layout.

Compatibility and Installation
Suitable only for selected 50cc, 70cc, 90cc, 110cc and 125cc four-stroke horizontal-engine vehicles with a matching 5-pin AC CDI. Some Coolster, TaoTao, SSR and similar applications may use this ignition system, but brand, engine size or identical connector shape alone does not confirm compatibility. Compare the original CDI's AC power type, terminal assignment, wiring, connector layout and mounting clearance before ordering.
Professional assessment and installation are recommended. Backfire can produce loud reports and hot exhaust gases. Avoid use near people or flammable materials and follow all applicable laws.
