Moturo Racing CDI unrestricted for GY6 125 150cc QMI engines

Moturo Racing CDI unrestricted for GY6 and 139QMA/B (50cc to 150cc)

The Moturo Racing CDI unrestricted for GY6 and 139QMA/B (50cc to 150cc) — the replacement that removes factory-installed rev limiters and unlocks the ignition curve. Powered by the alternator, two dual connectors, ready for installation.

The CDI sits between the alternator and the ignition coil and sends ignition current to the spark plug without a rev limiter. Connection via two dual connectors (six-pin: 1×4 and 1×2). The modified ignition curve releases more power and makes the engine rev more freely.

Suitable for four-stroke vehicles with GY6 and 139QMA/B from 50cc to 150cc, provided the ignition current is supplied by the alternator (AC). Not for battery-powered ignitions (DC).

Replacement takes about half an hour — unplug the old CDI, plug the new CDI into the connector, and secure the bracket.
