What is a CDI Pickup?
Before diving into the specifics of the Polini Thor 250 CDI Pickup, it’s essential to understand what a CDI (Capacitor Discharge Ignition) system is and how a CDI pickup functions.
In simple terms, the CDI system is an ignition system that uses a capacitor to store and discharge electrical energy to fire the spark plug at the right time. The CDI system ensures precise timing of the spark in the engine’s combustion chamber, optimizing performance and fuel efficiency. The CDI pickup, often referred to as the trigger, is a component that detects the position of the engine’s crankshaft and sends this information to the CDI unit to ensure accurate ignition timing.
The CDI Pickup is an essential component in managing the ignition timing of the engine. The Polini Thor 250 CDI Pickup, in particular, is designed for optimal performance, delivering consistent power while ensuring smooth acceleration and engine responsiveness.
