Howdy folks.
Just had my 1986 K75 delivered today - took a risk, bought it blind based on description, mileage indicated low at 15k, low number of owners etc, turned up today and liking some aspects of it - not liking others.
It's been re-painted at some point, including hammerite on front of engine block. More general wear and tear than I was expecting including a slight oil leak from currently undisclosed location .
However, I am a fussy britches so I'll learn to live with it and It does make it ripe for a mild resto.
Engine is smooth as you like and enjoying the roll on torque. Seating position is also excellent, first time I've sat on a brick and it feels absolutely spot on from the first turn of the wheel.
I now need to solve a few gremlins:
Rev counter only works after having run for a mile or two, until then it just kinda does its own thing - warning lights/neutral/gear indicator also all intermittent
Source and fix oil leak, I suspect clutch seal and possibly sensor on lower front engine block
Front brake feels very vague and weak despite braided hoses
If anyone can point me to a few associated threads I'd be much obliged.

Oil leak at front of block could be the oil pressure switch (easy fix) or the water/oil pump (not so easy) Pump leaks from little hole in front-bottom of engine, switch is covered in rubber boot, pull the boot off and see if it's full of oil. I'd flush and change the front brake fluid, getting them bled can be tricky, that would explain the mushiness. All in all considering it's a 30 year old bike sounds like you did pretty good.
