Clutch/Stalled 1982 KZ1100a2

TexasKZ AGAIN THANKS FOR THE CARBURETOR ISSUE!
So here’s what’s going on not all the time but when I shift from 4th gear to 5th gear it shifts in between the gears? Like it’s in neutral but very hard to get into gear actually grinding gears ⚙️. Trying to put back in goes back into gear easier when I can slow down shifts easier without grinding. Clutch plates? 
What all should I change? Also a one time deal this happened came up on a stop sign shifted down quick and the bike stalled? All the lights came on showed it was in neutral I was able to push the bike off to the side so I know it was in neutral would not start? Waited and turned on and off a couple of times and started back up Neutral safety switch?

Hi.
False nuetrals can happen for a number of reasons, although they usually happen in the lower gears because they get used and wear more.  A worn shift drum, worn or damaged shift forks, worn dogs on the gears, a dragging clutch, or shift linkage issues can all play a part.

I think it’s a dragging clutch going to change clutch plates, heavier spring first. Thanks for the suggestion 

Worn clutch plates and springs would not cause false neutrals or gear grinding.

Can you still 'find' a false neutral if gear changing without the clutch?

A dragging clutch is usually caused by-

improperly adjusted clutch cable
an improperly installed clutch release mechanism
warped steel plates in the clutch
the entire clutch assembly is coming loose from the transmission shaft

Worn friction plates and weak springs would cause the clutch to slip rather than drag.
