.... It is probably better suited to someone who has wrenching expertise....
That might be you and you don't know it yet.
I acquired my K less than two years ago on Craigslist. Besides oil changes, I had never worked on a motorcycle in my life. A week later I rode it up to the local BMW service desk and asked the service manager what they could do to replace worn bits, etc. The service manager suggested that old K bikes were relatively easy to work on and encouraged me to get a
repair guide and attempt the work myself.
I remember poking around on the bike in my driveway soon after, cautiously removing bits of the fairing, hesitantly unscrewing and screwing, and spending a lot of time on this and other K-bike forums. There's
lots of good K-bike maintenance and repair info and help online. I took advice from the forums, tackled one thing at a time, and slowly became more comfortable working on the bike. I learned quickly that the K bikes were well designed and fairly easy to work on with a few simple tools.
For months I was scared to remove the top of the fairing or the fuel tank. Couldn't figure out where the air filter was. Total newbie. But after doing those things once I realized how simple they were. I am comfortable enough now to almost completely disassemble and reassemble the whole bike.
I recommend you dive in and ask questions as you go. You might be more capable than you think.
