Dyna S Question..................

[PORKCHOPT]

Why Does The Instructions For The Dyna S Dual Fire Ignition Say That I Can't Use The Stock Coil From My '86 Sporty?

And Why Can't You Use A 3 Ohm Coil On The Street?

The Dyna S ignition is a race ignition (If memory serves me) the stock coil carry's too much impedance and won't put out the correct spark..

The Dyna S High Performance Ignition System, designed for Harleys, is a complete self-contained electronic ignition system built with the latest state-of-the-art engineering. This is the same ignition used by top racers over the past 2 decades. The Dyna S is completely housed behind the ignition cover and uses a magnetic rotor with the original spark advancer, so the factory advance curve is maintained.
Dyna high tech coils for Harley-Davidson Big Twins and Sportsters are American made, top quality performance coils . Tested and proven on street, racing, and touring motorcycles for over fourteen years. Dyna coils produce spark voltages in excess of 30,000 volts and spark energies second to none. All Dyna Coils are guaranteed against defects in materials and workmanship.

• The DSK6-1 Dyna S and coil system includes a DC7-1 high energy coil
• The DSK6-2 Dyna S and coil system is designed for single-fire applications; includes two DC10-1 Dyna coils

go with a dyna 2ki or 2ki-P for street use..
