Yamaha T50 4 stroke problems

[john allen]

1996 Yamaha T50 4 stroke has been linked & sync'd, new factory spark plugs. The carbs are not giving a problem, I have an intermittent miss & when going back to idle dies something, does restart right away. I realize it could be a coil pack. But I want know what controls the coil packs & tells them to fire on time. Any help would be appreciated. Thanks in advance

Ran the factory manual test for the CDI box. It completely failed the test three times. So again, Thank you John

Your welcome. Sorry to hear it's the CDI, they are not cheap. However, used ones in good shape are sold on websites like eBay, if you rather not buy new. Good luck.
