1985 ATC250R - No Spark

Looking for advice. So far I changed the spark plug which was of course the easiest. I still don't get a spark. This is for a 1985 ATC250R. The rest of the trike looks good. I bought it like this so i was taking a chance. I'd like to figure out the no spark problem without too much guesswork. Does anyone know the next logical step?

Thanks,
Sidd

Maybe you can test the ignition coil next. It can be checked with an ohmmeter.

Is there an official coil test procedure?

You can use an ohmmeter to check for continuity on the primary side and also check that there are no shorts to the secondary side. It's pretty straight forward.
