Unplug your kill switch and try it, if not that then check was the wires run into the coil. Sounds to me that something finally wore through and is grounding out on ya.

I did unplug the kill switch and no change. Also checked the wires from back of the ecu to the coils and all fine. But would both coils go out at the same time ?

I'd check the stator. My guess is either the flywheel ring came off or the stator is loose.
Just an FYI, don't put he bottom bolts in the recoil cover. I actually ground the cover some and left the bolts out. Now I can take it off without loosening the motor.

Need to pull the flywheel in order to see what the stator looks like under it since you are that far.

Not ohm test first ?

You could if you wanted to but I just figured since you already had the cover off of it then you could just pull the flywheel and see. The ring inside of it delaminates and cuts through the wires if you do have a problem Ohming it out.

Yeah you need a small flywheel puller. You can get them at a local autoparts store for about 20 bucks.

Did a test and the stator is dead. Got the flywheel off and the tank off. But there is no way to get the plugs past the motor mount to replace the old stator. How is this done or am i doing this wrong ??

Cable

You can get the stator cable out from under the engine, in between the motor mount and the frame, just underneath the recoil cover. I just did mine with motor mounted. Takes a little work, but can be done.
