Hi, i just bought a 2006 yz450f knowing it had no spark just trying to figure out what the problem is. The guy i bought it from said the only thing he tried was changing the plug. So here's my question would it be the the CDI box or the coil is there a special way to figure this out? The guy said that it was the CDI box. But I don't know any help would be appreciated, thanks.

Start with a manual:

Have you checked to see if it actually has spark or not?
