Motorcycle Repair: 72 ct90, dirty point, stator

Question
I have not spark. Changed rectifier, and checked voltage from stator ok, still no spark.

Answer
Todd, the bike needs a charged battery to fire the coils.  Assuming the battery is charged, the problem could be inteh coil or in the points.  Dirty point contact will prevent the coils from sparking. Take a points file and clean them and spray them with contact cleaner. and see if it doesn't get things working again.
