ZX11 starter goes bang

The problem child is a '93 ZX11C. Put in a new battery in November, lost my job in December so I pulled the insurance and parked it. Got a new job so I can go riding again! Just to be safe I put the battery on charge Saturday and checked it out on Sunday. Started just fine, took it around the block and stopped at the gas station for some fresh dead dinos, and declared it good to go.

Monday morning the bastard wont start. Hit the button and got firriierthunk. Tried a few more times just to confirm it. Thunk every time. Cuss a blue streak, put the charger on it and jump in the car for work. Replaying the tape in my mind I realize it was not a dieing battery no crank. It actually cranked good for the few seconds it cranked. Get home, take it off charge and it fires right up. Check things with a voltmeter and everything is good. Check it again just before bedtime and again fires up no problem.

This morning go out and again get firriierthunk. Only this time it was more like a bang with some bell ringing mixed in. Hit the button again, thunk. Put it in gear and rock it back and forth a few times, back in neutral and hit the magic button. Fires right up with no problems or strange noises. No rattling, clanging, banging or bell ringing. No sounds whatsoever to suggest something coming apart.

Any suggestions as to where to start looking?

The only problem is you have to split the cases to access it.

Sounds reasonable so I looked into it and have two thoughts -

Where the hell do I find it on the diagrams?! Went through every motor diagram on bike bandit and apparently the starter connects to the crank via pixie dust. I'm sure I can find it in my manual at home but there is the small matter of getting replacements.

Every other post I've found about a bad starter clutch the problem is slipping, not locking up the motor. Of course, this bike does like to do things differently.

Pulled the clutch cover and the alternator chain tensioner is busted. Apparently this a known issue. WTF is it with Kawasaki and chain tensioners?
