Top quality OEM Yamaha YFM400 YFM 400 Big Bear capacitor discharge ignition unit (CDI unit). CDI ignitions have become the system of choice due to their much hotter spark and ability to control spark timing through an internal computer. These units have the highest energy and best design today. Featuring a stronger bottom end and midrange power, these units provide better ignition and higher rev limits. One of the leading causes of CDI failure is a Regulator Rectifier or Ignition Coil. We carry both parts!
