Hello from Belgium! Last year I bought a 1993 K75S with slightly less than 50k miles on it as my first bike and so far I rode 5k happy miles with it.
The bike looked great but since I did not have any information about the service history I changed the air, oil and fuel filter, motor, final drive and transmission oil. I also changed the clutch cable and the crankcase breather hose. I installed a Hepco&Becker rack and tragkorbs (those are awesome as compared to the BMW tragkorbs), improved the tail light (added LED strips in the tail light as shown in one of the topics here) and added brake ‘eagle eye’ LEDs on the license plate holder. I also added fog lights (not yet on the pictures) and while doing that I wired relays into the headlight (also thanks to the information on this forum).
In the future I want to replace all fuel lines and maybe the rubber of the air intake manifolds/throttle body, the front fork oil and seals, the splines (never checked them, should be on the top of my list maybe). I also have the low seat version while I’m quite tall, so thinking about increasing the saddle height one way or another.
Please feel free to mention thing I should check or do as well.
Finally, some pictures…and…a thank you to everyone sharing information on this forum. Since it’s my first bike I had literally zero experience with motorcycle maintenance so this forum was of incredible value! :clap: :clap: :clap:
