Starter Motor not disengaging

I just completed my build . 81 cx500 d. Starter motor was grinding . I have an NWT system installed , after the ignition starts. The starter motor keeps spinning. I did all the tests to make sure the solenoid isn’t sticking. I even bought a brand new starter from Ricks and same issue persists. I can’t seem to figure out where to go next. Does it need to be a
Shimmed ? Is that even possible on this bike ?

It's not the starter. The starter clutch in the flywheel isn't releasing.

I’d pull off the spark plug leads and try the starter several times to be sure the solenoid/starter motor is releasing immediately when you take your finger off the button. I agree it’s probably the starter clutch (which is not part of the starter motor), but pulling the engine apart is a major task if it actually is the solenoid or starter button malfunctioning.

Can do the same test with the kill switch off. Determine if the engine is pushing the starter or the starter is still pushing the engine.

To check the starter clutch more directly, remove the starter and reach a finger into the port in the rear cover. You'll feel the starter reduction gear. It should turn freely in one direction, but not at all in the other.

Yea I did all the tests to make sure the solenoid is disengaging …. That seems to be fine. It’s also draining my battery hella quick .. because the stator thinks it needs more power …. I’m ripping out all the wires and starting again

If you have the original Capacitor Discharge Ignition (CDI) the stator consists of a set of charging windings that produce the power to charge the battery and a set of CDI windings that feed the CDI and are not in any way connected to the battery.

The charging part of the stator feeds power to the battery through the regulator/rectifier. Current can only flow through the rectifier in one direction so unless something is desperately wrong with the reg/rec or the way you have connected it current can NOT flow into the stator from the battery.
