All new for 2017 is the Tri-Spark Magneto replacement kit for 6 volt operation and the option of electronic advance and retard or fixed timing.
A further option to supplement the usual parallel twin version is the V twin or offset crank setup by popular request!
The kits suit a number of applications where the engine was originally fitted with a 3 bolt flange mounted magneto such as the pre-unit Triumphs, BSA A10s, Vincent twins and singles and Velocette to name a few. These kits utilise our Classic Twin TRI-0005 ignition installed in a small alloy distributor style housing made from solid AL and highly polished.
Due to many requests we have created new options including 6 volt operation, no advance and retard and offset crank options for v twins like the Vincent and rephased offset crank engines which are often 90 degree offset.
A typical kit for a Pre-unit Triumph on 12 volts (pictured above) includes the alloy housing, Tri-Spark Classic Twin electronic ignition, a dual lead ignition coil IGC-2012, HT leads, spark plug caps and fitting instructions. Part number MRK-0001
Options available: 6 volt operation, no advance and retard, offset crank or V-twin and single cylinder.
Why No advance retard? Some engines were originally equipped with a mechanical auto advance drive gear for the magneto and if you wish to retain the operation of this gear you will need to order the fixed timing option. A better alternative (more stable timing) would be to source a solid drive gear and let the electronic ignition control the timing.
Possible applications include Pre-unit Triumph, BSA 10 and A7, Vincent twins and singles, Norton Atlas, Velocette and Matchless.

This bike by one of our customers in Sydney prompted the 6 volt and no advance options to suit his engine - reports are it works better than ever !! He uses the original charging system with a small 6 volt lithium battery and amazingly the 6 volt version draws only 3 watts from the battery!
