It's simple to drain out the coolant, the plug is rear facing on the motor case, lower right corner. Some bikes have a plug, some have a hose there.
Filling it and purging all the air out is not easy.

Some suggestions - use a syringe, like those used for adding fork oil (Motion Pro) for adding the coolant. Turn on the key and let the pump run while you fill. The system will run and purge air as you go. Wait a few seconds as you add and get close to the top for the coolant level to drop. Do this a few times until it appears to stay full. Put the cap on and ride around the parking lot or the neighborhood. Usually this will purge the remainder of the air and you can top off the coolant. If the pump later seems noisy, it's cavitating a bit and you can add more coolant. None of this hurts the pump, it can basically run dry.
Empty the system holds 750ml. You won't add that much during a flush and fill.

IMO, you guys do not need to change the coolant. Ever.

I suspected this was a feel good service, not something that actually needed to be done.

Sounds like this is a procedure that is more like asking for trouble than maintaining a motorcycle. Just like removing the plastic in order to inspect the brass inserts and re-apply fresh Loctite, LOL!
Agreed & appreciate the feedback!
My motivation would be to insert fresh fluid cleaning out any manufacturing tolerance metal flakes or debri. I may delay the service a bit but will insert some fresh fluid at some point.
I appreciate everyone’s input & help!
