CDIs are not a common item to go bad.

Pull the ignition cover and check the flywheel/pickup.

My flywheel came apart and gave me a no spark symptom because the pickup ridge (I dont know what its really called) was no longer passing by the pickup therefore not initiating spark.

Hi there

mine, a 2006 YZ450F went out quitely and after changing the plug without results we checked the stator which gives off energy so there are only a few items remaining. The CDI or the ignition coil, well the wiring too I suppose.

Lets hope that tomorrow I know more.

Hello there

In my case it was the stator, well at least they have it here in the country. Soon I can :thumbsup: again on the YZ450F
