CDI unit for 125–150 cc 4-stroke scooters. This is the ignition module: it generates the pulse for the coil, which produces the spark at the spark plug. Without a rev limiter.
If there is no spark or the engine stalls when warm, check the spark plug, the coil and the wiring first, and then the CDI unit. Make sure the connector matches. When diagnosing the ignition, it is handy to compare the spark with another CDI unit known to work.
What to consider when choosing:
- connector type
- number of pins
- engine power
