Hey guys, I was just about to start rebuilding my forks and ran into ran issue. I went to loosen the bottom Allen bolts and this is what I found. Sorry for the bad pictures ill try and get better ones when I remove the forks from the bike.

You may just need to file flats into the side and use and open end wrench.

By F64: doesn't look oem.

Agreed. Looks like somebody installed hex bolts in place of the allen bolts. The bottom allen bolts should be installed with aluminum gaskets. I forget what the manual specifies, but I put a high temp thread sealant on the threads to act as a thread locker.
Just an FYI. There's a pdf manual available for the 81 KZ650.

I'm now thinking someone stripped or drilled the Allen head out and rigged these in vs replacing the Allens.... Great
