LK LEAPING KNIGHT Ignition Coils Editorial Review
**** The product has garnered a largely negative reception from customers, particularly centered around its performance issues. Users have reported that the device fails to properly operate when installed on SSR140 models. Many complaints highlight that despite following setup procedures, the product does not start the engine, simply cranking without igniting. A few customers noted that the display lights up during cranking, suggesting that the device is receiving power, but that it does not translate into functionality. In instances where customers sought a replacement, they found similar results, with the CDI box only generating spark without successfully initiating engine operations. This led to frustration among users, many of whom have expressed disappointment in wasting their investment due to the persistent issues. The Consensus is clear: potential buyers should tread carefully, as the product has not met the expectations of those hoping for a reliable performance upgrade. **
