Universal 6-core stator coil, compatible with the Yamaha JOG50 Westlake 90 1PE40QMB engine, suitable for 50-90cc scooters of the same platform.

This product is an OEM-spec solenoid coil (generator coil), specifically designed for Yamaha's classic, high-performance two-stroke Mountain Max and VMAX 600/700 ER snowmobiles. It is an exact match for OEM part number 8DM-81410-00 and is a critical electrical component reinforced to withstand the extreme conditions of cold, humidity, and high vibration encountered during snowmobile operation. This product provides a stable and reliable power supply to the snowmobile's CDI ignition system, electric starter, and various electric heating devices. It is essential for resolving charging or ignition issues and ensuring optimal performance during polar expeditions and competitions. 【Product Information】 Original Part Number: 8DM-81410-00 Compatible Models: Yamaha Mountain Max Series, VMAX 600 ER and VMAX 700 ER (Exact compatibility should be verified based on the year of manufacture and engine model; checking the Vehicle Identification Number (VIN) is recommended). Engine Type: Two-stroke twin-cylinder or three-cylinder engine (600 cc/700 cc). Function: This product is the main component for generating power for the snowmobile's magneto ignition. It must operate reliably even in extremely low temperatures and essentially performs the following functions: Ignition System Power Supply: Provides high voltage to the multi-cylinder CDI capacitor discharge ignition system, ensuring precise ignition of each cylinder at high RPMs. Charging and Starting: Charges the battery and ensures the proper functioning of the electric starter system. Heater Power Supply: Provides (after voltage regulation) the basic power for high-performance electrical devices such as handlebar and seat heaters. Symptoms: This product is designed to correct typical problems caused by damage to the stator coil in extremely cold and harsh environments: difficulty starting in cold weather or complete inability to start using the electric starter/pull starter (no spark). Sudden engine stalling, misfires, or loss of power at high RPMs. Malfunction or very low performance of the electric heater. Rapid battery discharge after use. Abnormal instrument readings or warnings of electrical faults.
