**【Product Function and Significance】】
⚙️ Main Control Unit of the Ignition System: The CDI (Capacitor Diode) is the "brain" of the electronic ignition system. From engine speed and position signals, it precisely controls the ignition timing (advance) and sends a trigger signal to the ignition coil, generating a high-voltage spark. Its performance directly determines engine power, responsiveness, and efficiency. 🚀 Improve engine performance: Replacing a faulty CDI effectively resolves issues such as starting problems, rough idling, poor acceleration, high-rev misfires, increased fuel consumption, and uneven power delivery. 🔧 Easy installation: This product matches the original dimensions and interface standards, ensuring perfect compatibility with your vehicle's wiring harness. Installation typically involves simply removing the old part and inserting the new one – without any modifications to the wiring.
🛡️ Stable and durable design: Thanks to high-quality electronic components and a stable circuit housed in a high-temperature, shock, and moisture-resistant casing, this product ensures continuous and precise ignition control, even under demanding driving conditions.

**【Compatibility and important installation steps】】
✅ Compatibility check (absolutely essential): This product is only compatible with vehicles equipped with an original CDI unit with part number 61N-85540-00.

Please locate and verify the part number of your original CDI module (usually printed on a sticker or the housing) before purchasing to ensure proper compatibility. This verification is essential for the proper operation and safety of your vehicle. 🔧 Safety Instructions for Installation: 1. Disconnect Power: Always turn off the ignition and disconnect the negative battery terminal before starting any work to avoid short circuits or electric shocks. 2.

Installation: Align the connector of this product with the corresponding socket on the vehicle's wiring harness and carefully but firmly insert it until it clicks into place (if present). Reinstall the CDI unit. 4. Function Test: Reconnect the negative battery terminal. Start the engine and check idle stability. Perform test rides to assess responsiveness and acceleration at low, mid, and high RPMs.
