You can set the timing statically using the built-in LED on the module - it simply requires that you accurately position the engine at the fully advanced crank position for the setup procedure.  

Offset Crank Option available. 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 note section.

Please contact us directly if you require a variation, such as no advance and retard.
