Motor was running great. Went out in morning to warm up and it just kept cranking with no ignition. Fuel is getting to the carbs but do not see any spark to plugs. I disconnected the black w/yellow stripe wire to eliminate failure switches and still no start. Where can I go from here.

There is an ign troubleshooting test on the CDIElectronics.com website, for your motor. I assume you have the six coil model, with ADI igntion?

There are four coils. One for each cylinder for what I can see

You ignition is also covered in the CDI Troubleshooting guide. Follow the steps laid out, it will lead you to the solution very quickly.
