My bike is not getting any spark and I changed the plugs. This was not a sudden thing it started happening slowly, like it took my bike longer to start up slowly and than one day while riding she just stopped. I peddaled home and changed the plug thinking that was the problem but nope. I pedaled and nothing, not even a single spark. I took of the spark plug and kept it on the CDI to test for spark and not a single thing. Additionally I checked all wiring and the magneto and everything looks okay. So I was wondering if the CDI or magneto just up and die randomly (they are both stock) and just needed other opinions before I bought new parts. Thanks ahead.
