Tri Spark Ignition System, Classic British Twins, Singles

Tri-Spark Classic Twin ignition system – 12 volt system for positive OR negative earth/ground installations.

The Tri-Spark Classic Twin utilises 21st century technology to provide simple installation without the black box, superior running and easy starting without kick back. Many years of experience with classic motorcycles and extensive development has resulted in this high precision, zero maintenance, compact and reliable system. Built in self test mode and LED for setting the timing.

The Tri-Spark ignition system uses the direction and speed of rotation to optimise the starting performance which is critical for kickstarting. This also helps to avoid damage to the electric start mechanism which is easily done in some machines if the engine kicks against the starter.

Tri-Spark stator unit (trigger and control module) – replaces the points plate
Tri-Spark trigger rotor – replaces the auto advance unit and points cam
12 page illustrated colour instruction booklet
