Ed may still be on the right path. Could be hitting inside the engine sprocket cover
If that were the case, wouldn't the sound happen regardless of whether or not throttle is being applied?

It is stock...
Maybe put it on the center stand and spin the wheel.
I only hear it when both of two conditions are met... 1: the bike is in motion, 2: throttle is being applied. If I let go of the throttle, I don't hear it. If I push the bike in neutral with it off, I don't hear it. If I put the bike on the center stand, turn the bike on, and apply throttle, I don't hear it... Both of those conditions have to be met...

No.
Consider this -
When the throttle is being applied with the tranny in gear the engine sprocket is pulling the top length of the chain taut as it pulls on the drive sprocket. When that happens all the slack in the drive chain ends up on the bottom length of the chain. This extra slack in the bottom length of the chain can cause the chain to rub things if the chain has too much slack in it.
One word of caution though - do NOT adjust the chain such that there is no slack in it. Doing that will very quickly ruin a chain because it needs some slack to cope with the fact that as the rear axle rises to a point where the axle, engine sprocket center, and swing arm pivot are aligned the distance between the sprockets increase. If the chain is adjusted with insufficient slack the chain will stretch and be damaged. Be sure to follow the instructions in the Kawasaki Service Manual or the bike's Owner's Manual for adjusting the chain. Ed

Do you have checked the rear wheel bearings and the bearing in the rear sprocket hub ?
Under acceleration a worn out bearing can cause a scraping or sliding noise (dry bearing without grease).
