sackcheck

Or can someone tell me about the pickup coils at least?

This Problem has been occurring more often and is keeping me from ridding Before it would happen like this(go to warm the bike up in the morning and it would not start, let it sit an hour or so. boom fires right up. I assumed it was the carbs cause that was it's main problem at the time. But recently I have rebuilt the carbs and the bike runs perfect with exception it dies 10min's after warm up. It's just like someone walked up an hit the kill switch "silence". I checked all plugs for spark and nothing, it still turns over fine and gets all it's air an fuel but no spark, so I know it's not any of the kill switches. I'm scared to ride it fearing that it might die at the wrong moment and kill me. Cause last time it died I was at mid rev and that was kinda of a weird momment. If anyone has any ideas I would greatly appreciate it THANKS!
