it works perfectly
Starting is faster, throttle response is better, and the engine sounds much cleaner. Installation was super easy; I just disconnected the old one and connected this one. I've been using it with zero issues. For the price, it's totally worth it if you want to squeeze a little more performance without having to deal with complicated modifications. I recommend it.

Great upgraded CDI
This Universal CDI Box is a solid upgrade for my 125cc atv. Installation was easy, and it fits perfectly on my Coleman 125cc without any modifications. I noticed an immediate improvement in acceleration and overall performance after adjusting the ignition curves andnl cycling through the modes. The high voltage output feels consistent, and the unit seems durable and well-made, with good heat dissipation. Compared to the stock CDI, the unit does take up more space but it is a good performer. Overall, it’s a reliable, high-performance replacement part that’s easy to install and makes a noticeable difference on the bike.
