Start with the basics.

Gas
Spark
Juice

1. You have gas flowing to the carbs? If I am not mistaken petcocks have screens that clog. Gas filter, clog fuel line.

2. do you have spark at the plugs? Did you pull the plugs yet? , Bad coil?

3. I am assuming the battery is fully charged since it's an 81 with no kickstart.

Ruling out the battery & carbs next I would test the coils.
Before you do any testing make sure you have a fully charged battery. Test the ignition coils.
Measure the resistance between the primary (low-tension) wire and ground or ground terminal. It should be .5 to 1.5 Ohms. The primary wire should be the small wire going to the CDI box or points. Next measure the secondary (high-tension) wire and ground. This should be high, like 6000 to 13000 ohms. If the coil is out side the specs given in the shop manual the coil might be bad.
