1979 KZ650SR won't start.

This is a friends bike that has been sitting for years. Has fire to the points and to the back of the coils but no spark.
What say yee?
Any help will be greatly appreciated.

Do you have ignition points or is there an electronic ignition in the bike? It would be hard to believe that both coils would fail at the smae time. Try this: remove the spark plug caps and take an ohm meter and see if you have continiuty through the caps.

While the caps are off bring the ignition leads close to the cylinder head and look for spark. If the spark is good than the caps are bad. If still no spark then the coils might be bad.

You mentioned having voltage at the primary side of the coils. Was this close to battery voltage or quite a bit lower?

Points ignition. I just know I got a reading...at the primary side. Don't know what it was. I will check.
Thanks
