50CC & 150CC CDI Fits nearly all 50CC & 150CC Scooters and ATVs.
NO REV LIMIT VERSION CDI! Others charge more, A LOT MORE for the no Rev limit version.
What is a CDI module? A typical CDI module consists of a small
transformer, a charging circuit, a triggering circuit and a main capacitor.
First, the system voltage is raised up to 400-600 Volts by a transformer inside
the CDI module. Then, the electric current flows to the charging circuit and
charges the capacitor. The rectifier inside the charging circuit prevents
capacitor discharge before the ignition point. When the triggering circuit
receives triggering signals, the triggering circuit stops the operation of the
charging circuit, allowing the capacitor to discharge its output rapidly to the
low inductance ignition coil, which increases the 400-600 V capacitor discharge
to up to 40 kV at the secondary winding at the spark plug. When there's no
triggering signal, the charging circuit is reconnected to charge back the
capacitor.
Our CDI modules are compatible with various versions
of 50cc-150cc GY6/QMB139 4-stroke scooter engines as well as 50cc-150cc Chinese
made Honda-style 4-stroke scooter engines.
Please check your CDI module
with the pictures on each item page carefully prior to ordering.
