Motorcycle Repair: I HAVE A 2002 HONDA XR100...., honda xr100, cam chain

Question
I HAVE A  2002 HONDA XR100. THE CHAIN POPED OFF AND NOW THE BIKE DOES NOT HAVE SPARK. WHAT WENT WRONG  

Answer
Hi Dean.
 Which chain?  The cam chain or the drive chain?  The two are not related to each other or to spark.

Give me some details as to what happened and what you did to assess it and then we can work on what needs to be done to fix it.
