Please help! I'm about to lose my mind! I'm not sure if it's a carb issue or what. It will rev up like someone is holding throttle wide open and the kill switch or key won't shut it off. They work fine, otherwise. I have put in new reeds and even swapped carbs with another bike. I've had tors engaged and disabled and it still does it. I'm about to set it on fire! Cdi issues?
