Is your old Kawasaki Bayou acting up or not sparking right? This might be the fix! This is a brand new, high-performance CDI (Capacitor Discharge Ignition) box designed specifically for the Kawasaki KLF 300 Bayou A, 2x4 and 4x4 models from the years 1986 and 1987. The CDI box is a crucial part of the ignition system – it controls the spark timing for the engine. This one from Labwork is a direct replacement that should bolt right up and plug into your existing wiring harness. It replaces OEM part numbers 21119-1025, 21119-1065, and 21119-1193. It's a solid-state unit with a plastic housing, built to handle the vibrations and heat of an ATV engine. Installing a new CDI can often solve hard-starting, misfiring, or no-spark issues if the old unit has failed. It comes with a 90-day manufacturer warranty for peace of mind. Made in China. This is for the front of the vehicle where the ignition components are typically located. A great, affordable fix to get your classic Bayou back on the trails. Make sure your model and year match before ordering!
