FITS MODEL PART # HONDA 500, 550, 750 4-cylinder 69-78 DS1-2 GL1000 75-79 DS1-3 FITS MODEL PART # KAWASAKI 900, 1000, 1100 4-cylinder 73-85 DS2-1 KZ550, 650, 750 4-cylinder (all) 76-82 DS2-2 FITS MODEL PART # SUZUKI 550, 750, 850, 1000, 1100 4-cylinder (ND) 77-81 DS3-2 1000/1100 82-83 DS3-2 SELF-CONTAINED ELECTRONIC IGNITIONS •Totally self-contained for easy installation • All components fit under the point cover, replacing the original points •Dyna S utilizes all the time-proven Dyna III circuitry but comes in a smaller, condensed package •Use with coils having 3-ohm primary resistance FITMENT APPLICATION PART # W/ single-plug heads Street, 5-ohm (black), pair DC10-1 W/ dual-plug heads Street, 5-ohm (black), pair DC8-1 FITMENT APPLICATION PART # W/ single-plug heads Race only, 3-ohm (green), pair DC3-1 W/ dual-plug heads Race only, 3-ohm (green), pair DC1-1 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 •Made in the U.S.A. NOTE: Not recommended for use with OEM coils. NOTE: 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. DC10-1 DC1-1 DS1-3
