Contact Breaker (Points) Ignition

Contact breaker (points) ignition is one of the earliest types of motorcycle ignition systems, primarily used in vintage and classic bikes. It operates by mechanically opening and closing electrical contacts, which initiates the ignition process. As the points open, they interrupt the current flow in the primary coil, generating a spark for combustion.

The contact breaker system consists of a cam-driven mechanism linked to the engine’s camshaft. When the cam lobe pushes on the breaker arm, it causes the contact points to close, allowing current to flow through the coil. As the cam turns, it eventually separates the points, breaking the circuit and inducing a high-voltage pulse in the secondary coil.

Adjusting the timing of the contact points is critical for optimal engine performance. Incorrect gap settings or worn points can lead to poor firing, misfires, or difficulty starting the motorcycle.
