Book Excerpt: 1995-2006 Yamaha XJR1200, XJR1300, XJR1300SP Repair Manual IGNITION SYSTEM

GENERAL INFORMATION All models are fitted with a fully transistorised electronic ignition system, which due to its lack of mechanical parts is totally maintenance free. The system comprises a trigger, pick-up coil, ignition control unit and ignition HT coils (refer to the wiring diagrams at the end of Chapter 8 for details). All models are fitted with two HT coils. A throttle position sensor mounted on the right-hand end of the carburetors provides throttle opening information to the ignition control unit. The ignition trigger, which is on the left-hand end of the crankshaft, magnetically operates the pick-up coil as the crankshaft rotates. The pick-up coil sends a signal to the ignition control unit which then supplies the ignition HT coils with the power necessary to produce a spark at the plugs. Each HT coil works on the 'wasted spark' principle with each spark plug sparking twice for every cycle of the engine; once on the compression stroke and once on the exhaust stroke. The system incorporates an electronic advance system controlled by signals from the ignition trigger and pick-up coil and the throttle position sensor.
