I have a 2008 kx250f that just stopped running while riding it. No spark at all. I replaced the stator, coil, and harness. I also purchased a used CDI off of a 2007 from ebay and still no spark. The grounds seem fine. Any other ideas? I know the used CDI could also be bad but what are the chances? Any help would be greatly appreciated, especially if you are near DFW. Previous owners brought it to a shop and this is their diagnostic... See attached
