That's screwed. At the very least you will probably have blown the rectifier in your voltage regulator (I'm assuming you have a charging system), but if it doesn't run you prob need a CDI as well.
The only real way to be sure is get out a manual and a test meter and go to town. Beyond that you are replacing parts on a guess....
