Precision Timing for Evolution Sportsters

A healthy ignition system relies on the accurate reading of the engine’s position. This electronic pickup plate (replaces OEM #32400-94) uses a high-sensitivity magnetic sensor to track the ignition rotor. By sending a precise signal to the ignition module, it ensures that your spark plugs fire at the exact moment required for optimal combustion. This results in crisper throttle response, improved fuel efficiency, and a more stable idle.

Engineered for High-Heat Environments

Located behind the timing cover, the ignition sensor is subjected to extreme temperatures that can cause inferior plastics and resins to melt or crack. Standard Motor Products utilizes advanced potting compounds and high-temperature wire insulation to protect the internal circuitry. This specialized construction ensures that the sensor remains functional even during long summer rides or heavy stop-and-go traffic, preventing the heat-related failures common in older factory units.

Direct-Fit, Professional-Grade Solution

Standard Motor Products (SMP) has been a trusted name in the automotive and motorcycle industry for over 100 years. This sensor is a direct-fit replacement, meaning it installs into the factory location without the need for modification. It features the correct wiring harness length and connectors to interface seamlessly with your Sportster’s electrical system, making it the preferred choice for both professional mechanics and DIY enthusiasts.

Troubleshoot Hot-Start and Misfire Issues

If your Sportster runs perfectly when cold but begins to stumble or die once reached operating temperature, the ignition sensor is the most likely culprit. By replacing your aging sensor with this new assembly, you eliminate the intermittent internal shorts and signal degradation that cause these symptoms. It is a vital part of any high-mileage tune-up for 1995–2003 Evolution Sportsters.

Fitment and Compatibility

The MC-SPA2 sensor assembly is designed specifically for the following applications:

• Harley-Davidson Sportster (1995–2003): Fits all 883, 1100, and 1200 Evolution models (XLH, XL, Custom, Hugger).
• Replaces OEM Part Numbers: 32400-94, 32400-94A, and 32400-94B.
• Note: Not compatible with 1994 or earlier models requiring the 32400-80 series sensor.

OEM Quality and Precision Engineering

Standard Motor Products (SMP) has been a leader in automotive and motorcycle electronics for decades. This Ignition Sensor Assembly (replaces OEM #32400-80A) is a direct-fit part that installs perfectly inside the engine’s nose cone. The sensor utilizes a precise magnetic pickup to track the position of the ignition rotor, ensuring that your ignition module fires the spark plugs at the exact millisecond required for peak engine efficiency.

Built for Extreme Heat and Vibration

The ignition sensor is located in one of the harshest environments on a Harley-Davidson—the nose cone, which sits just inches away from the exhaust and cylinder heads. This SMP assembly is built with high-temperature wire insulation and a reinforced sensor housing that resists the “melting” or “oozing” failure common in older factory units. By utilizing superior potting materials, this sensor remains stable even during long-distance summer rides.

Solve Common Ignition Failures

If your bike runs fine when cold but starts cutting out or misfiring once it reaches operating temperature, the ignition sensor is the likely culprit. This electronic pickup plate replaces the aging sensor and wiring harness, eliminating the intermittent connections and thermal breakdown that plague older Harleys. It is the most cost-effective way to restore factory-level reliability without the need for expensive aftermarket programmable ignitions.

Installation and Fitment

This is a “plug-and-play” style replacement that uses the factory-style wiring. It is designed to fit the following models:

• Harley-Davidson Big Twin (1980–1995): Fits Shovelhead and Evolution (Evo) models including Softail, Dyna, and Touring.
• Harley-Davidson Sportster (1980–1993): Fits Ironhead and early Evolution Sportster models.
• Replaces OEM Part Numbers: 32400-80, 32400-80A, and 32400-80B.
