Download the CDI troubleshooting manual and get a meter and DVA adapter. Test the ignition system as it could be stator or timer base..

any simplified way of diagnosing it without a good meter? i have a basic digital OHM meter, stator was tested by a mechanic resistance is good, voltage is good..
could anything else be the culprate ?
has 2 brand new batterys. wires are clean

Faztbullet is correct. Without the proper equipment it's impossible to check out these ignition systems correctly. Unless you have plenty of $$$$ and just start replacing parts.
