Compatible with the stator coil, magnet coil and generator coil of the Yamaha XJR400 motorcycle, original reference 4HM-81410-00-00 (compatible with models from 1993 to 2007).--DTEKGAZ

This product is a high-precision stator coil (magneto coil/alternator coil), specifically designed for the Yamaha XJR400, a classic four-cylinder street motorcycle. It is an exact match for the original part number 4HM-81410-00-00 and covers the entire production cycle of this model (1993 to 2007). As the heart of the charging system, this coil ensures a stable and reliable power supply to the high-revving four-cylinder engine, restoring its optimal performance and torque. 【Important Product Information】 Original Part Number: 4HM-81410-00-00 Compatible Models: Yamaha XJR400 Compatible Years: 1993 to 2007 (Compatible with all current models) Function: This component is the central part of the magneto ignition system. When the crankshaft drives the external flywheel, the coil interrupts the magnetic field, generating three-phase alternating current. This current powers all of the vehicle's electrical systems (including the complex four-cylinder ignition system, headlights, instruments, etc.) and charges the battery. This product effectively resolves the following common problems caused by aging or overheating of the stator coil (common in high-revving four-cylinder motorcycles) or by insulation faults: The battery remains consistently weak even after extended driving. The headlights and all other lights are unusually dim, especially at idle. Starting with the electric starter is difficult and requires push-starting the engine. The engine stalls abruptly at high RPM due to a power interruption. During testing, the charging voltage is extremely low or zero (it should normally be between 13.5 and 14.8 V).
