Goofit Single Pulse Ignition Sensor Compatible with Honda XLR125/NX125/FL400/XR250 ATVs Original Part Number: 30300-HA7-671 Crankshaft Position Sensor

【Crankshaft Position Sensor Specifically Designed for Classic Honda Small-Displacement Off-Road Motorcycles】This single pulse sensor is specifically designed for various classic Honda small-displacement off-road and endurance motorcycles. It meets original Honda specifications and is identical to original part number 30300-HA7-671. Its shockproof, dustproof, and waterproof housing allows for use in the harshest off-road conditions. It precisely monitors crankshaft speed and position, providing a stable and reliable ignition pulse signal for the CDI ignition system. It is a crucial component for reliable engine starting and optimal torque delivery in the low and mid-range RPMs. **[Perfect Compatibility with Many Classic Vehicle Models]** This product directly replaces part number 30300-HA7-671, as confirmed in the manufacturer's original catalog. This part is specifically designed for the following classic motorcycle models: Honda XLR125, Honda NX125, Honda NX125 Falcon (FL400) (market-specific model), Honda XR250 (specific year/production version). (Note: This product is fully compatible with the above models using this part number. Please check the part number in your vehicle manual or on the original parts before purchasing to ensure compatibility. This is the most reliable method for checking compatibility. Different part numbers may be used depending on the XR250's year of manufacture.) **[Resolving Ignition Problems in Classic Off-Road Vehicles]** Replacing the original ignition sensor, which can be damaged by persistent vibration, aging of the ignition coil, or internal moisture, effectively resolves the following problems: difficulty starting, especially in cold weather; rough idling and stalling at low RPMs; weak acceleration or sporadic "coughing" noises; unexplained engine stalling while riding. [Professional Installation and Air Gap Requirements] This product is a precision electromagnetic component, typically mounted in the engine's magnetic cover or at a specific location in the crankcase, along with the trigger connector on the flywheel. Crucial to proper installation is the precise adjustment of the air gap between the sensor head and the trigger connector on the flywheel. This air gap must meet stringent requirements (typically 0.3 to 0.8 mm) and be adjusted using a non-magnetic feeler gauge (plastic/brass) and in accordance with the Honda Repair Manual. A correct air gap is essential for signal strength. [Scope of Delivery] 1 Single Pulse Trigger Sensor
