The timing on the electronic ignition isn't adjusted properly. Or you have the wires for the L & R cylinders reversed. If you're still having problems, put the points back in. If it runs, then somethings wrong with the new ignition - timing, crossed wires or it's a piece of junk. Stock is best - stick with the points.

Your could have tooth lacking from the flywheel.try rolling the motorcycle in kit some inches forward or decrease back,then see if it is going to work together. Ebay is a sturdy place to come across factors if mandatory

Sounds like the timing is off.
