Welcome to the forum and sorry for the problem with your EX
If the valves are not moving it indicates the camshaft is not turning - for the camshaft to not turn indicates either the chain connecting the crankshaft to the cam is worn out, broken, bolts holding cam sprocket have come out or sheared off, crankshaft is broken or the motor is not actually turning when using the starter motor.
You need to determine what is not moving. Take the plug out of the alternator cover, take a valve adjuster cover off and rotate the crankshaft counter clockwise with a wrench. If the valves move it indicates the chain is connected and turning the cam. Remove the wrench, take the spark plug wire off and use the starter motor to turn the engine. Look in the hole and see if the flywheel rotates when the starter is engaged.
Let me know what you find out and I guide you to determine what is wrong.
