SINGLE-FIRE ELECTRONIC IGNITION SYSTEM • All the features of the famous Dyna “S”, plus the special feature of firing the front and rear cylinders independent of each other, allowing a much more accurate timing of each cylinder • The stock ignition system fires both cylinders at the same time, which works fine for the front cylinder but the rear receives the “wasted” spark when the cylinder has started its intake stroke; this can result in harder starting, increased engine vibration, backfire and raw fuel being spit back into the carb, all creating a power loss • Dyno and top-speed testing have shown a dramatic improvement in power in all areas; bikes with hotter cams show the greatest improvement APPLICATION CHART FOR DYNA COILS WHEN USING DYNA “S” IGNITION SYSTEMS FITMENT APPLICATION PART # W/ single-plug heads Street, 5-ohm (black), pair DC10-1 W/ single-plug heads Race only, 3-ohm (green), pair DC3-1 W/ dual-plug heads Race only, 3-ohm (green), pair DC1-1 FITMENT APPLICATION PART # W/ dual-plug heads Street, 5-ohm (black), pair DC8-1 W/ dual-plug heads Race only, requires two coils, 3-ohm (green), each DC6-1 PART # DESCRIPTION DS6-2 For 70-99 Big Twin, 71-85 XL using a mechanical advance unit PART # DESCRIPTION D-101 Tach adapter • If you truly want to get the most out of your stock, slightly modified or all-out customized Harley-Davidson, you need a Dyna “S” single-fire ignition system • Made in the U.S.A. NOTE: Not recommended for use with OEM coils. NOTE: On later models, an advance weight mechanism is required. NOTE: This unit must be used with special Dyna coils; see coil chart for correct coils. NOTE: Tach adapter is required when using an electric tach. NOTE: Not for fuel-injected models. DC10-1 DC1-1 DC6-1 DC8-1 D-101 DS6-2 DUAL-FIRE IGNITION AND COIL KIT • Complete electronic ignition system built with the latest state-of-the-art engineering • The same ignition used by top drag and road racers to set records and bring home victories over the past decade • The Dyna S is completely housed behind the ignition cover and uses a magnetic rotor with the original advance unit, so the factory advance curve is maintained • Coils provide spark voltages in excess of 30,000V and spark energies second to none • The DSK61 Dyna S and coil system includes a DC7-1 high-energy coil • Made in the U.S.A. NOTE: Not for fuel-injected models. NOTE: Later models will require the use of a mechanical advance unit. PART # DESCRIPTION DSK61 For 70-99 Big Twin, 71-85 XL
