Was wondering if someone could help me out with my TTR 225 I've went through the whole ignition system and replaced it except for the CDI box. I've checked the grounds and the wiring and I have even bypassed the ignition to see if that was it and that wasn't. It did spark for like one or two cranks and then nothing after that.

So should I just get the CDI box or is there something else I can do
