No spark

My 1978 Kawasaki KZ650Sr Still has no spark just replaced the key switch and made huge progress but it is still not getting spark i pulled the points cover off and inspected the points they seem to be ok the bike has 9000 miles what could be the problem?

Got any power at the coils? Do you have a test light or DVOM?

With ignition switch ON, can measure voltage at the dual connector supplying both coils. (See image below.)
The wire might be solid red instead of red/yellow.

How does this voltage compare to voltage measured across the battery terminals?

Good Fortune!

The spark plug caps at the end of the plug wires can go bad. I had spark on only one cylinder when I bought my 79 SR and found that three of the plug caps were bad.

Once upon a time I had a dead bug smeared across the contacts on the kill switch. No spark on any cyclinders.
I would suggest that you need to get a multimeter and trace back from the coils to find where you have voltage

You could also rig up a simple test light with a 12V bulb and some wire instead of a multimeter
