Picked up a new to me 1992 K75s with 83,xxx miles, runs like a dream. I figured that (and the entry test) qualified me for an account on your lifesaving forum, thanks for having me.
I've already begun the disassembly process to see what I'm working with and I wanted to get some advice on a few things.
1. What should I deal with first in terms of maintenance, damage prevention, inspection, (etc.) on an older bike that I'm unfamiliar with?
B) Is it a sin to grind unwanted tabs off of the frame of a completely stock bike?
4) Should I invest in a $600 (plus a day's drive) parts bike with a seized engine? It's been cafe'd out and modernized, and it's a 1991 K75rt while mine is the superior '92 K75s.
Let me know what you guys think, and thanks for the years of suggestions built up on this forum that I'd otherwise have to find out the hard way.

Welcome, Isaac!
There first thing you should do is remove the fuel cap assembly, drain the fuel completely and send us a photo of what you see in there. Replace the fuel filter, and replace all the hoses in there with new SAE30R10 submersible high pressure hose. Ted Verrill created this guide (http://www.verrill.com/moto/newkbike.shtml) for new owners. Follow it.
What tabs are you considering removing and why them? Why would you want a moto with a seized engine and many of its parts removed to "modernize" it? Are you laundering money?
Don't concern yourself with committing sin by your behavior with this moto. Your past behavior probably has you marked already. :laughing4-giggles:

The fuel should all be good, the bike has been ridden regularly and I drove it home from Portland with no problems. But I'll definitely take a look and start replacing some filters!
The bike with the seized engine would be for parts for my running bike. It has already been chopped up and cafe'd with new parts all over so I was wondering if there would likely be enough left to make the drive worth it.
And as for tabs, I was mainly referring to the ones that hold the arms on the rear that the tragkorbs mount over.

The worth of that butchered moto is anybody's guess. As far as the tabs you want to cut off, that's also a mystery.
Here's a photo of a K75 without z-racks or side cases. Where are the tabs?

Welcome! Your moto looks pretty nice. As Laitch suggests, get the guide for a new owner and go through the bike. These machines are incredibly reliable if maintained properly, so there is a lot of payback in keeping up with it.
Dealer servicing can easily cost more than what you paid for the bike, so it's well that you do all your own wrenching. The good news is that these bikes aren't all that bad to work on. I can do an entire year's worth of maintenance in a weekend without breaking a sweat.
First thing I would do is bleed/flush the brakes. The condition of the fluid that comes out will give a good idea of how well the previous owner cared for the bike. Take your time and enjoy the job, think of maintenance as foreplay, the more attention paid to it, the better the ride will be.

Welcome nice looking moto. Looks like fairing is in good nick and just needs a good cleaning.
You can add the last 7 digits of the VIN into the MaxBMW model search link. Good luck

I didn't expect someone else to be picking up a damn near identical bike to mine so soon. Guess I'm not the only one up here anymore.
