DYNATEK-HARLEY Electronic Ignition System — Black, Dual – 70-84, 86 Big Twin, 79-84 Touring, 84 FXR, 84 Police, 70-85 Sportster

The Electronic Ignition System is a self-contained unit that uses Hall Effect magnetic sensors for reliable spark timing.

It improves overall performance by changing timing less than three degrees, extends plug life, and eliminates the use of points and condensers.

Easy to install and used and endorsed by many championship racers. ⚡️

Operation with the Dyna S ignition system requires the use of an aftermarket 5 ohm coil such as part # DC7-1, or a stock points coil from early Shovelheads; not recommended for operation with OEM coils. 🔧

Street applications require use of a 5-ohm coil; on '84-'99 fitment models listed, an advance weight mechanism is required, and on '86-'03 XL and '80-'99 Big Twin models listed, a mechanical advance unit is required.

Made in the USA.
