S&S Cycle HI-4N: The Toughest Digital Ignition for Evolution Engines

The S&S Cycle HI-4N Single & Dual Fire Ignition Module is the next generation of the legendary HI-4 series. Engineered to solve the heat and vibration issues that plague plastic-bodied ignitions, the HI-4N features a heavy-duty billet aluminum housing that acts as a heat sink to protect the sensitive electronics within. This module is the ultimate upgrade for Harley-Davidson Evolution riders who demand precision timing and a “set-it-and-forget-it” level of reliability.

Versatile Ignition Modes: Single or Dual Fire

The HI-4N is designed for maximum flexibility. With a simple flip of a switch, you can configure the module for Dual-Fire (using your stock coil) or Single-Fire (firing each cylinder independently for smoother operation and reduced vibration). This makes it an ideal choice for riders who want to upgrade their ignition module now and potentially move to a high-output single-fire coil system later without buying a new ignition.

Optimized Performance Tuning

Tuning your V-Twin has never been easier. The HI-4N features on-board rotary switches that allow you to select from four different advance curves, ranging from stock to aggressive performance maps. This allows you to eliminate engine “pinging” (detonation) while maximizing torque. Additionally, the module features a separate rear cylinder timing adjustment, allowing you to offset the timing of the rear cylinder to ensure it runs cooler and more efficiently than the front.

Selectable Start Modes: Electric or Kick

Whether you are riding a modern electric-start Softail or a custom kick-only chopper, the HI-4N has you covered. The “Kick Start” mode provides a spark on the very first compression stroke for immediate ignition. The “Electric Start” mode delays the spark for two revolutions, allowing the starter motor to reach full speed—this virtually eliminates engine kick-back, protecting your starter and ring gear from expensive damage.

Rugged Construction & Built-in Protection

The HI-4N is built to survive. The electronics are fully encapsulated (potted) to protect against moisture, oil, and mechanical shock. It includes a built-in adjustable rev limiter that can be set in 100-RPM increments to protect your valvetrain. A built-in static timing LED allows you to time the engine perfectly without the need for a strobe light, making installation straightforward for the DIY mechanic.

Fitment and Compatibility (1984–1999)

This module (Part # 550-0501) fits “nose cone” ignition applications:

  • Harley Big Twin (1984–1999): Evolution (Evo) engines (Softail, Dyna, and Touring).
  • Harley Sportster (1986–2003): All 883 and 1200 Evolution Sportster models.
  • Custom V-Twins: Direct replacement for S&S V-Series and other aftermarket Evo-style engines.

Dynatek TC88: Precision Digital Ignition for Carbureted Twin Cam 88 Engines

The Dynatek TC88 Digital Performance Ignition System is the definitive electronic upgrade for Harley-Davidson Twin Cam 88 motorcycles equipped with a carburetor. Designed to replace the restrictive factory ignition module, the TC88 unlocks your engine’s hidden potential by providing a more powerful spark and customizable timing maps. Whether you are running a stock 88ci motor or a heavily modified 95ci or 98ci big-bore kit, this module provides the digital precision needed for maximum performance.

Ultimate Tunability: 16 Selectable Advance Curves

The factory ignition timing is often a compromise designed for emissions rather than power. The Dynatek TC88 changes the game with 16 built-in advance curves, organized into four groups to suit different engine states and fuel grades. These curves allow you to optimize torque and horsepower while eliminating the engine “pinging” or detonation often caused by modern low-octane fuels. With simple rotary switches, you can dial in the perfect timing for your specific riding style.

Protecting your valvetrain is critical when pushing a performance V-Twin. The TC88 features an integrated rev limiter with 8 selectable positions, ranging from a conservative 5,750 RPM to a high-performance 7,250 RPM. This allows you to set a safety ceiling that matches your engine’s breathing capabilities and internal component strength, ensuring you don’t over-rev during aggressive gear changes.

Seamless Plug-and-Play Installation

There is no need for wire cutting or complex soldering. The TC88 is a direct “plug-and-play” replacement for the stock Harley module. It utilizes the factory 12-pin connector and works in harmony with the original sensors, including the MAP sensor and Crank Position Sensor (CPS). This ensures a clean, professional installation that maintains the integrity of your motorcycle’s wiring harness while providing a significant boost in electrical efficiency.

High-Energy Spark & Intelligent Starting

The TC88 is engineered to deliver a higher energy spark than the OEM unit, leading to more complete combustion, cleaner spark plugs, and smoother idling. Additionally, the module features an intelligent starting algorithm that ensures the engine is spinning at the correct speed before firing, which significantly reduces the strain on your starter motor and prevents the violent “kick-back” common in large V-Twins.

Dynatek High-Performance Ignition System: Precision Timing for Classic & Modern V-Twins

The Dynatek High-Performance Ignition System is a professional-grade solution for Harley-Davidson owners looking to unlock the full potential of their 1970–2003 machines. For decades, Dynatek has been the industry leader in V-Twin electronics, and this system continues that legacy by providing a completely digital, high-energy spark that outclasses factory equipment. Whether you’re running a classic Shovelhead, a reliable Evolution, or a high-strung Sportster, this ignition system delivers the accuracy and power required for peak performance.

Eliminate Mechanical Weak Points

Traditional ignition systems rely on mechanical advance weights and springs that wear out over time, leading to erratic timing and power loss. The Dynatek system replaces these antiquated components with a fully digital advance map. By utilizing solid-state sensors and a high-speed microprocessor, the system calculates the perfect spark timing hundreds of times per second. This results in a smoother idle, crisper throttle response, and more consistent power delivery across the entire RPM range.

Customizable Advance Curves and Rev Control

One size does not fit all in the world of V-Twin performance. This high-performance kit features selectable advance curves, allowing riders to tailor the ignition timing to their specific engine build, fuel grade, and riding style. Additionally, the built-in adjustable rev limiter provides a critical safety net, protecting your valvetrain from over-revving during aggressive riding or missed shifts. These features make it the ideal choice for high-compression engines that are prone to detonation or “pinging.”

Single-Fire Technology for Smoother Operation

While many factory systems utilize “Dual-Fire” ignition (firing both cylinders simultaneously), the Dynatek system is capable of Single-Fire operation. By firing each cylinder independently on its own compression stroke, the system eliminates the “wasted spark” that occurs on the exhaust stroke. This technology significantly reduces engine vibration, lowers operating temperatures, and improves overall combustion efficiency, leading to a more refined riding experience.

Intelligent Starting Algorithm

V-Twin engines are notorious for “kick-back” during startup, which can cause expensive damage to starter clutches and primary drives. Dynatek’s intelligent starting technology manages the initial spark timing to ensure the engine is spinning freely before firing. This results in reliable, effortless starting even on large-displacement engines or in cold weather conditions, preserving the life of your battery and starter motor.

Fitment and Application Guide

This high-performance system is designed for “nose-cone” ignition setups on the following models:

  • Harley Big Twin (1970–1999): Fits Shovelhead and Evolution (Evo) models.
  • Harley Sportster (1971–2003): Fits Ironhead and 883/1200 Evolution Sportster models.
  • Custom Engines: Direct fit for S&S, RevTech, and Ultima engines using classic ignition configurations.
The Dynatek High-Performance Ignition System is more than just a replacement part; it is a fundamental upgrade to your motorcycle’s “brain.” With a static timing LED for easy installation and a rugged, heat-resistant housing, this kit provides the “set-it-and-forget-it” reliability that serious riders demand. Experience the difference that professional-grade digital timing makes on your next ride.

Dynatek 2000i: The Ultimate Programmable Ignition for Harley-Davidson

The Dynatek 2000i Programmable Electronic Ignition Kit is a high-tech powerhouse designed to replace the aging ignition systems found on Harley-Davidson motorcycles from 1971 to 1998. This self-contained digital module fits completely within the engine’s nose cone, providing a sleek, hidden installation that removes the need for an external ignition box. Whether you are riding a Shovelhead or an Evolution engine, the 2000i brings modern digital precision to your classic V-Twin.

Customizable Performance: 8 Advance Curves

Every engine is different, and the Dynatek 2000i respects that. With 8 selectable advance curves, riders can fine-tune their ignition timing to match their specific engine build. Whether you have a stock cruiser, a high-compression street sleeper, or a dedicated drag bike, you can easily select a curve that maximizes horsepower and prevents engine pinging. This level of adjustability ensures optimal throttle response throughout the entire RPM range.

Single-Fire or Dual-Fire Versatility

The 2000i is incredibly versatile, allowing you to run your bike in Single-Fire or Dual-Fire mode. In single-fire mode, each spark plug fires independently, eliminating the “wasted spark” found in factory setups. This leads to a smoother-running engine, reduced vibration, and improved idle stability. The module is designed to work with standard coils or high-performance aftermarket coils, giving you total control over your spark delivery.

Built-In Adjustable Rev Limiter

Protect your engine from over-revving with the integrated, adjustable rev limiter. With settings ranging from 6,000 to 7,500 RPM (adjustable in 250 RPM increments), you can push your machine to its performance limits with the peace of mind that the ignition will safely manage your engine’s ceiling. This is an essential feature for riders who have invested in high-performance cam sets and valvetrain components.

Intelligent Starting and Kick-Back Protection

One of the most valuable features of the Dynatek 2000i is its intelligent starting algorithm. The module delays the ignition spark for the first two revolutions of the engine. This allows the starter to get the engine spinning freely before ignition occurs, virtually eliminating engine kick-back. This feature protects your starter motor, ring gear, and primary components from the violent shocks associated with hard-starting V-Twins.

Dynatek Dyna S Dual Fire Ignition: Proven Performance for Classic Harleys

The Dynatek Dyna S Dual Fire Ignition Kit is a time-tested performance solution for Harley-Davidson enthusiasts looking to modernize their vintage V-Twin electrical system. Designed for models from 1970 through 1999, the Dyna S is a high-performance, solid-state ignition that fits entirely within the cam cover. By replacing mechanical points or failing factory electronic ignitions with a precise magnetic-pulse system, the Dyna S ensures your Shovelhead or Evolution engine runs smoother and starts faster.

Self-Contained Magnetic Pulse Technology

The beauty of the Dyna S lies in its simplicity. Unlike modern digital ignitions that require complex programming, the Dyna S uses a specialized magnetic pickup and rotor system. There are no moving parts to wear out, meaning you will never have to deal with pitted points or wandering timing again. This maintenance-free design provides consistent, high-energy spark delivery regardless of engine temperature or RPM, making it a favorite for both daily riders and custom builders.

Improved Starting and Idle Quality

Classic Harleys can be temperamental during startup. The Dynatek Dyna S addresses this by providing a stronger spark at lower voltages, which is critical during the heavy draw of a starter motor. Riders will immediately notice a crisper throttle response and a significantly more stable idle. By providing a more complete combustion cycle, the Dyna S helps eliminate the “coughs” and “stumbles” often associated with aged ignition systems.

Direct Dual-Fire Compatibility

This kit is a Dual-Fire system, meaning it is designed to work seamlessly with your motorcycle’s existing dual-fire coil. It utilizes the “wasted spark” method, firing both cylinders simultaneously, which simplifies the installation process. The Dyna S is engineered to work best with 5-ohm coils (standard for street use) or 3-ohm coils for racing applications, offering the flexibility to match your specific riding style.

Rugged Construction & Easy Installation

Built to survive the intense heat and vibration of a V-Twin engine, the Dyna S features a heavy-duty aluminum base plate and high-quality electronic components. Installation is straightforward: the module bolts directly into the factory ignition location in the nose cone. Because the entire system is contained behind the timing cover, you maintain the clean, classic look of your motorcycle without the need for unsightly external ignition boxes or additional wiring harnesses.

Fitment and Compatibility (1970–1999)

The Dynatek Dyna S (Part # DS6-1) is compatible with:

  • Harley Big Twin (1970–1999): Shovelhead and Evolution (Evo) engines (uses the mechanical advance mechanism).
  • Harley Sportster (1971–2003): Ironhead and Evolution Sportster models.
  • Custom Engines: Ideal for S&S and other aftermarket V-Twins based on the classic nose-cone design.
For over three decades, the Dynatek Dyna S Dual Fire Ignition Kit has been the gold standard for riders who want “set-it-and-forget-it” reliability. Whether you are maintaining a survivor Shovelhead or upgrading an Evo chopper, the Dyna S provides the powerful ignition performance you need to enjoy the open road with total confidence.

Dynatek 2000i Programmable Digital Ignition: Modern Precision for Classic Harley-Davidson

The Dynatek 2000i Ignition Kit is a game-changing performance upgrade for Harley-Davidson motorcycles from 1970 to 2000. For riders tired of dealing with inconsistent mechanical advance weights, worn-out points, or failing factory electronic modules, the 2000i offers a completely integrated, digital solution. Housed entirely within the engine’s nose cone, this kit eliminates the need for an external ignition box, providing a clean look and high-tech performance for Shovelhead, Evolution, and Ironhead engines.

Complete Control: Selectable Advance Curves

One of the standout features of the Dynatek 2000i is its versatility. The module features on-board switches that allow riders to choose from 8 different advance curves. Whether you are running a bone-stock cruiser or a high-compression, large-displacement build, you can fine-tune the ignition timing to prevent detonation (pinging) and maximize power delivery. This level of customization ensures optimal throttle response throughout the entire RPM range.

Adjustable Rev Limiter and Safety Features

Protecting your investment is easy with the 2000i’s built-in adjustable rev limiter. With settings ranging from 6,000 to 7,500 RPM, you can safely push your V-Twin to its limits without the risk of over-revving. Additionally, the module includes a specialized static timing LED, allowing you to time your engine perfectly without the need for a strobe light, and a dedicated VOES (Vacuum Operated Electric Switch) input to maintain fuel economy and performance under varying engine loads.

Single-Fire or Dual-Fire Compatibility

The Dynatek 2000i is designed to be the only ignition module you will ever need. It can be configured to run in Dual-Fire mode (using your stock coil) or Single-Fire mode (using two separate coils or a single-fire coil). Single-fire operation fires each spark plug independently, eliminating the “wasted spark” and significantly reducing engine vibration while improving idle stability—a must-have upgrade for performance enthusiasts.

Intelligent Electronic Kick-Back Protection

Every Harley rider knows the frustration of engine “kick-back” during startup, which can damage starter drives and primary components. The Dynatek 2000i features an intelligent starting algorithm that delays the spark during the first few revolutions. This ensures the engine is spinning at the proper speed before firing, resulting in smoother, safer, and more reliable starts every time you hit the button or kick the pedal.

Fitment and Compatibility (1970–2000)

The Dynatek 2000i (Part # D2KI-1P) fits models equipped with the “nose cone” style ignition, including:

  • Harley Big Twin (1970–1999): Shovelhead and Evolution (Evo) models (excluding Twin Cam).
  • Harley Sportster (1971–2003): All Ironhead and Evolution Sportster models.
  • Custom Builds: Ideal for S&S, RevTech, and Ultima engine applications.
Stop settling for dated ignition technology. The Dynatek 2000i Ignition Kit brings 21st-century digital precision to your classic Harley-Davidson. With its ease of installation, programmable features, and proven track record on both the street and the strip, it is the single most effective way to improve the rideability and power of your V-Twin.

Dynatek 2000i Ignition Kit For Harley
