990991 Sensor, crankshaft position Sportster

For owners of 2004 and 2005 rubber-mount Sportsters, this crankshaft position sensor is a key component for maintaining engine performance. This OEM-style replacement sensor from MCS replaces part number 32804-04B. It monitors the crank rotation to provide the necessary data for the ignition system to function correctly. If your Sporty is experiencing erratic idling or is difficult to start when warm, this sensor may be the issue. It is designed for a simple plug-and-play installation, restoring the factory-standard timing accuracy that these Evolution engines require. Keeping your sensors in good working order is essential for a reliable ride, whether you are commuting or hitting the backroads.
