15. IGNITION SYSTEM Mongoose/KXR 90/50 PULSER COIL INSPECTION This test is performed with the stator installed in the engine. Disconnect the A.C. generator connector. Measure the pulser coil resistance between the blue/yellow and green wire terminals. Pulser Coil Lead Resistance: Mongoose/KXR 90): 121.1/20°C Mongoose/KXR 50): 80160/20°C Note: The readings in this table are taken with a YF-3501 Tester. REMOVAL Refer to chapter 14 for the A.C. generator removal. IGNITION TIMING INSPECTION The CDI unit is not adjustable. If the ignition timing is incorrect, inspect the CDI unit, pulser coil and A.C. generator and replace any faulty parts. Remove the fan cover. Warm up the engine and check the ignition "F" Mark Advance Mark timing with a timing light. When the engine is running at the ignition timing is correct if the "F" mark aligns with the index mark within 2°. Ignition Timing: Mongoose/KXR 90): BTDC28°/4000rpm Mongoose/KXR 50): BTDC15°/1700rpm 15-8
