Standard Motor Products Ignition Sensor Assembly For Harley Sportster 1995-2003

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.
