i've heard of CDI boxes doing some pretty crazy ****. and i have the basic idea of what they do. but i've also heard that they either work or they don't. anyone ever have a CDI box that still put out spark but on the wrong stroke.

 

generaly but not always they work or don't work checking is a proccess of elimination where you all coresponding components and takes having am manual and specs but they don't fail very often and it usualy will turn out to be something else
