For Timing Tri-Spark Ignition, it uses the direction and speed of rotation to optimize 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. We designed this unique system because you want your engine to fire up easily!
Timing Tri-Spark Ignition – Classic Twin for offset crank
The Classic Twin is generally used for parallel twins with a 360-degree crank configuration; however it may be used on engines with offset cranks such as 270-degree. A modification is required to the trigger rotor for offset crank applications to reposition the magnets to suit your engine. Please add the Offset Crank Rotor to your cart and specify the degrees and for what bike in the delivery note section.
