Now you can replace your old magneto with a modern electronic ignition from Tri-Spark. Suits 3 bolt flange applications such as  Lucas magneto K2F, K1F.  These magnetos were used on pre unit single cylinder Triumph and BSA bikes  Please check with us for compatibility. 

• No more magneto problems - now you can have all the benefits of electronic ignition 
• Fully digital - Extreme spark stability - LED static timing indicator
• No springs or weights - Electronic spark advance - 12 volt operation
• Completely eliminates the magneto
• Easy starting without kickback 
• No black box 
• Race proven
• Extreme temperature safe
• Idle stabilisation
• The electronics are made in Australia 

For single cylinder Triumph and BSA bikes, the kit includes the Aluminium Housing, Classic Twin ignition,  Tri-Spark 12-Volt ignition coil (Lucas Style IGC-1012), HT lead and spark plug cap.

 A battery is required to get the best possible results such as easy starting.  A 12-volt 4 Ahr battery would be fine - should be about half the size of a house brick.

The Magneto Replacement for Triumph/BSA Singles (MRK-0005) has electronic advance and retard built in. It requires a solid drive gear (no springs and weights) which is not included in the kit.

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.  

Only suitable for 12-volt systems.
