Electronic Ignitions & RPM Limiters

DYNA 2000 Digital Ignition Systems

Programmable digital ignition is adaptable to the performance level of virtually any bike. It offers adjustable advance curve, rev-limit, VOES switch on or off, retard mode for use with nitrous or turbo bikes, and single or dual fire triggering. Options are set using switches on the back of the unit. Designed to be plug-compatible with connectors on factory ignitions on most models made since 1984. All systems use stock ignition pick-up, and none work with fuel injected engines.

Dyna 'S' Ignition Systems

Systems use magnetic rotors with Original Equipment spark advance mechanisms to retain the factory advance curves and replace points and condensers with a high-performance dual or single-fire system. Dyna 'S' ignitions change timing less than 3 degrees from 0-8000 RPM and feature improved performance, easy installation and a 3-year factory warranty. Completely self-contained, and install behind points cover.

Spyke High-Performance Ignition System

Using the latest electronic designs, Spyke's ignition system delivers the hottest spark possible, giving easier starting, better combustion and more power.

In-The-Cone Multi-Spark Ignition

Multi-spark photoelectric trigger fires the spark plug up to four times on each compression stroke. Completely fits in the nose cone and works with Spyke coils which have a fast voltage rise time to meet the demands of multiple discharge.

Time delays light circuit so the starter and ignition get all available battery voltage.

80,000 Volt Dual Tower Coil

Generates high voltage for the hottest spark possible. For use with Spyke and other high performance ignitions.

V-Thunder Ignition Computer by Competition Cams

From heart-attack-serious racer to weekend warrior, the V-Thunder Ignition Computer offers unmatched programming capability to perfectly tailor ignition performance to virtually any Evolution® Big Twin. Unique 'switch programming' allows access to over 20 advanced features such as dwell control, nitrous or blower retard, VOES timing, rear cylinder timing trim, cam calibration and minimum and maximum advance adjust. The computer offers 15 built-in programs to match most popular engine combinations, but for the serious tuner, an optional PC interface module allows unlimited access to the internal computer settings and provides infinite adjustment capability. Installation is a super-simple 'black box' swap, without the need to even get inside the nose cone.

RevTech Electronic Ignition Systems

These RevTech high-energy inductive storage systems replace the Original Equipment point-triggered or electronic ignitions fitted to all Sportster® and Big Twin models since 1970. They're Hall cell triggered and unaffected by R.P.M. changes, dirt, oil or any other contaminants that may get into the ignition housing. Each system uses separate magnets in the rotor to turn the coil on and off producing the correct dwell time of 130 degrees (camshaft). This minimizes coil heating and keeps the primary resistance low which keeps the primary current and energy output at optimum levels. These same magnets are mounted in a planar configuration relative to the Hall cell at a radius of just under an inch resulting in perfect timing accuracy because the module-to-module timing is inherent in the desIGNITION and never needs to be adjusted. Benefits of the single-fire system include increased gas mileage, prolonged spark plug life, easier starts, and a smoother ride with more available horsepower. All of this is accomplished by not firing both sparkplugs every time a cylinder comes to top-dead-center, but only the necessary Plug. This means that the piston which is in the overlap position and still has any raw gas in the cylinder will not be fired needlessly, and the motor will not be 'fighting' itself. Each kit comes complete with everything necessary to perform the installation quickly and easily.

Ignition Kits without Advance Unit Assembly

Fit Sportster models from 1971 thru 1979 and Big Twins from 1970 thru 1979

Note: For proper results, matching high-performance coils must be installed in conjunction with the CCI #59-752 and #59-755 single-fire kits.

Ignition Kits with Advance Unit Assembly

Fit all Sportster and Big Twin models from 1980 to present

Note: The single-fire ignition kits listed above, require the additional purchase of the Crane Tachometer Interface Adapter listed elsewhere on this page to correct the readout of the electronic tachs on late-model motorcycles.

Ignition Wiring Adapter

Install the latest stock or high performance ignitions on models with the earlier connector. The adapter has 7-pin male connector to fit wiring harness introduced on 1991 models and 8-pin female 'Deutsch' connector at other end that fits electronic ignitions introduced on Dressers and Sportster models in 1994 and used on all models since 1996.

RevTech Digital Electronic Ignition

The RevTech Digital Ignition is a great leap forward in ignition systems for Harley-Davidson engines. Its advanced digital technology enables you to adjust it for the specific configuration of your high performance engine. The RevTech Digital Ignition produces an electronic digital advance that is much more stable and reliable than mechanical advance, but the biggest advantage is the ability to select from four built-in advance curves. These curves permit maximum performance on engines built to different performance levels. An important safety factor is included with the built-in RPM limiter to protect the engine. It is adjustable in four increments from 6000 to 7500 RPM. The RevTech Digital Ignition stands above the others in ease of installation as well as performance, It is plug-compatible with the seven-pin 'D' plug fitted to most models since 1991. It uses the Original Equipment Hall effect timing pickup used on stock electronic  ignitions since 1984. For those looking for top-performing single-fire ignition timing, a separate output is provided for the second coil, and a dedicated tach output is also provided. To keep installation simple, optional wiring kits adapt it for use with most models built from 1984 thru 1990.

Notes:
1) only carbon-core suppression spark plug wires should be used with this ignition system. Copper or spiral-core wires may cause electronic interference and/or damage the unit.
2) For correct operation of this ignition system, the Original Equipment electronic ignition pickup and OEM 32402-83 rotating cup that attaches to the camshaft (that have been fitted to all models since 19a4) MUST be used.
3) This ignition system may not be installed on motorcycles equipped with kickstart ONLY.

RevTech Coils

These coils have the correct primary resistance necessary for use in single-fire applications. A wide variety of mounting brackets for various applications may be found elsewhere in this section. Sold in pairs.

Note: Dual-fire operation (one coil firing both spark plugs at the same time) requires the use of a CCI #59-713 high-performance coil or an OEM 31614-83 coil (that has been fitted to most models since 1984).

Crane 'Hi-4' Internal High-Performance Ignition Systems

Crane's high-performance electronic ignitions have the entire unit mounted directly to the ignition timing plate for ease-of-installation and trouble-free operation. They're available in single-fire and dual-fire "race' models as well as an 'EPA-friendly' version that is certified legal for use in all 50 states (E.O. #D-225-43). They all feature fully-adjustable advance curves, switching for kick or electric start, a tachometer output, and a rev-limiter that's adjustable from 4,000 to 8,000 RPM . The "race" single-fire kit has adjustable rear cylinder timing, and both single-fire kits have the necessary circuitry to correct the read-out of the electronic tachometers on late-model motorcycles. They fit all Sportster® models from 1983 to present and Big Twin models from 1984 to present that still have their Original Equipment ignition timing rotor in place. They may also be installed on all Sportster models from 1971 thru 1982 and Big Twins from 1970 thru 1983 when their mechanical advance units and point ignitions, or early electronic ignitions and rotors are replaced by an OEM 32402-83 ignition timing rotor. Detailed installation instructions are included.

Note: Crane recommends the use of Spiral core spark plug wires and high-performance coils with at least 2 ohms primary resistance for these ignitions. Ignition unit will not work in conjunction with racing air shifter installed.
