Starter spins on bench but won’t crank bike

Hello new member here and would appreciate any assistance. I live in Guelph Ontario Canada which is about 45 ride from Toronto. My 82 CX500 Custom was my daily driver all season and after sitting for just a couple of weeks won’t crank.
I tried a few known good batteries and even load tested them but wouldn’t crank. Solenoid just clicks. I have full voltage >12V through solenoid (power side). I pulled the starter and cleaned everything, replaced brushes and performed ground mod. On the bench it spins with power but in the bike it doesn’t. I can spin the engine over easily with a small rachet on the crank bolt.
The engine isn’t seized and plugs are out. Could I have a weak starter? I can’t seem to locate a new one online. Any suggestions?

I had a look in the garage today. I have a starter that I can give you. I do need to test it though. I'll let you know how that goes.
The starter turns OK. I'm fitting it to my bike to see if it will start the engine. Got too cold so haven't quite got the starter installed. Perhaps I'll have it in tomorrow.
Also, what's this "ground mod" for the starter?
I tested my spare starter today. It cranks the engine. I expect that it would be a good idea to open and clean the starter. I'll leave that to you.

We need to arrange delivery of the starter. I could meet you about half way if necessary.
No charge, I'm giving it to you.
