DC Ignition CDI for / GY6 50cc (139QMB) Scooter Engines

DC CDI Unit for GY6 50cc and 139QMB Scooter Engines

This DC CDI module is built to bring spark timing back into line on GY6 and 139QMB scooter engines. It can be installed in place of the original OEM unit on scooters that use a DC ignition setup. As part of our GY6 50cc scooter parts range, it is intended to help your engine keep running dependably.

Direct Fit and Compatibility

A 2/4-pin split connector lets the unit plug straight into the existing wiring harness. No cutting or rewiring is required, so swapping out the old module is simple. The CDI is made to suit several engine sizes in the GY6 family, namely 50cc, 80cc, 125cc, 150cc and 169cc.

Construction and Durability

The housing is black and filled with epoxy, which helps it resist vibration and moisture. That protection supports steady operation in tougher riding conditions. If the scooter has trouble starting or begins misfiring, the CDI may need to be replaced.
