Here is our "No rev limit" racing capacitive discharge ignition (CDI) module for 4-stroke 125cc & 150cc GY6/QMB139 Honda-style Chinese made go-kart engines. This version of CDI has 6 pins (6 wires) with a rounded connector as shown.

This gas scooter part is a high performance CDI designed to increase your acceleration and performance. A simple "plug and play" switch of your CDI is all it takes for increased acceleration, particularly on hills and steep inclines.

125cc & 150cc GY6 style engines are commonly found on Chinese made scooters, pit bikes, go karts, dirt bikes, and ATVs.

This is an upgraded version of Monster Scooter Parts part number X98-1391 CDI. This CDI provides better RPM display readings as compared to the Version 1 125cc & 150cc racing CDI.

Compatibility is based on matching wiring and connectors. Please ensure your make and model have the same connector and number of pins prior to ordering.

Note: 4-stroke and 2-stroke engines require different engine timing. Though they may appear visually similar, a CDI module from a 4-stroke engine cannot be interchanged with a CDI module from a 2-stroke engine.
