New to me 87 K75. When sitting still, locking the front brake and sharply pressing down on the handle bars to compress the front suspension, the bike immediatly rebounds with a few cyclic bounces before it settles down. Seems like the front fork is not providing any return dampening.

I haven't had anything older than a 95 BMW in a long time, so everything I have ridden since 1997 when I got my first Oil Head (R1100RS) has had Paralever/telelever, with the expected excellent anti-dive and jounce damping.

when I mentioned this to the prior owner,......he seemed bewildered and stated that he had recenly changed the fork oil.

It is usually the fork oil being well past the use by date that causes that. Maybe using a heavier grade would suit better. I would be changing it regardless of what the PO said as it could be as simple as not enough oil.
Being that you are new to bricks have a read of the "you just bought a K bike so what now" on the portal page, there is a wealth of info for new owners there.
