Goofit Single Pulse Generator (Crankshaft Position Sensor) Compatible with KTM Duke 620/640 and SMC/SXC 660 Series High-performance ignition sensor for single-cylinder engines

[Crankshaft Position Sensor for KTM LC4 Single-Cylinder Engines] This crankshaft position sensor was specifically designed for classic KTM models with the LC4 single-cylinder engine, such as the Duke 620, Duke 640, SMC 660, and SXC 660. It meets original specifications and is compatible with part number 58439034000. Thanks to its robust and high-temperature resistant construction, it withstands the strong shocks and vibrations of high-torque single-cylinder engines. It precisely monitors crankshaft speed and position and delivers an accurate ignition signal to the engine control unit (ECU or CDI, depending on the year of manufacture). This sensor is essential for strong low-end torque, reliable starting, and optimal engine performance. **[Precise Compatibility with Multiple LC4 Platform Models]** This product directly replaces part number 58439034000 and is suitable for the following KTM LC4 engine models (exact compatibility must be confirmed based on the model year): KTM Duke 620, KTM Duke 640, KTM SMC 660 (Superbike), KTM SXC 660. (*Note: This product is compatible with the above LC4 engine models using this part number. Please check the part number in your motorcycle's service manual, on original parts, or use the VIN for an accurate search before purchasing. Differences may exist depending on the production year and fuel injection/carburetor version.*) **[Fixes Ignition Problems on KTM Single-Cylinder Engines]** Replacing original sensors damaged by vibration, aging due to high temperatures, magnet failure, or a broken wiring harness effectively resolves the following issues: Engine will not start or has Starting difficulties (no cold start) (crankshaft signal): Extremely rough idle, easy stalling, loss of power, or misfires during acceleration. The warranty light illuminates, and crankshaft sensor fault codes are stored. [Professional installation and air gap adjustment (on some models)] This product is a precision electromagnetic component. It is typically mounted on the left side of the engine, near the flywheel or timing sprocket. On some LC4 models, precise air gap adjustment between the sensor head and the trigger teeth of the flywheel (or signal disc) is required during installation. This air gap must meet strict requirements (e.g., 0.5 to 1.0 mm) and be set using a non-magnetic feeler gauge, as per the KTM Service Manual. On some models, the air gap can be preset via the mounting bracket.
