12 Volt Dual Output Ignition Coil.Includes copper cored plug leads, length 75cm./29.5" and aluminium spacers, fixing bolts, nuts & washers.
Plug caps not included (available separately).
Applications:
- British Twin Cylinder motorcycles with 12 volt electrics and Sure-Fire/True-Fire electronic ignition system
- Twin cylinder machines fitted with a distributor and 12 volt electrics, including Triumph, Bsa, Norton, Sunbeam, Royal Enfield, AJS & Matchless. Converts to wasted spark ignition, eliminating troublesome distributor cap and rotor arm, boosting spark energy. Once fitted, better starting and reduced maintenance are the result.
- Japanese twin/four cylinder motorcycles with mounting hole centres @ 90mm or 102mm (note: two coils required for four cylinder motorcycles).
Important notes:
This coil must only be mounted by the two metal bar ends; this is the only way for heat to escape from the primary winding. Coils found to be overheated will not be covered by the warranty. An adequate heatsink should be provided, ideally using two aluminium spacers and a minimum of 80 square cms. of cold surface area. A good mounting to clean metal on the frame/chassis will normally suffice, but an extra aluminium heatsink is recommended, to allow the coil to work at its optimum, even at high temperatures and over extensive running periods.
