Stator coil, magnet coil, generator charging coil compatible with Yamaha MT-03 XT660 series motorcycles--DTEKGAZ

This product is a universal magneto ignition coil assembly specifically designed for common 250cc ATVs. Compatibility is primarily determined by the key dimensions of LC172 mm or LC170 mm (corresponding to the coil core thickness) and not by a specific vehicle make or model. This product is widely compatible with locally manufactured, assembled, or rebranded ATVs that use this standard magneto ignition, including vehicles with engines such as "CB," "BSE," and "Jinling." It thus provides a universal solution for cost-effective repairs or replacements. 【Key Product Information】 Key Compatibility Specifications: Coil Thickness (LC): 172 mm or 170 mm (Important dimension; please measure your old coil before purchasing). Compatible Engine Displacement: Approximately 250cc air- or liquid-cooled 4-stroke single-cylinder ATV engines. Compatible Models/Makes: Engine/Vehicle Reference: May be associated with engine codes such as JLA-21B and 923. Brand Note: Generally compatible with ATVs, beach buggies, and agricultural vehicles with part numbers CB250, BSE250, Jinling 250, or other unbranded models with similar stock engines. Important Note: This is a universal part; however, compatibility with all 250cc models cannot be guaranteed. Final compatibility depends on actual dimensions. Part Function: Main component of the magneto ignition system, typically consisting of: Generator Coil (Lighting/Charging): Powers headlights and taillights and charges the battery (if present). Ignition Coil (Triggering): Transmits the crankshaft position signal to the CDI unit, thus controlling the ignition timing. Troubleshooting: This product addresses common problems caused by a burnt-out stator coil, a short circuit, or an aging coil: Engine won't start (no spark). The engine starts, but the electrical system doesn't work (headlights malfunction, battery won't charge). Rough engine running, vibrations at idle, or misfires during acceleration.
