FS~1993 K1100 RS
« on: June 04, 2026, 08:26:13 AM »
Time to pass this machine onto whoever wants a spare parts bike to use.  About 67,000 miles, in fair condition, runs, but there are electrical issues, and others.  I have a couple of extras (ignition switch, brand new rear tire) Let me know if you want to continue.  Not giving it away for free, an honest deal.

Nothing specific happened, 30 year old bikes behave differently, every time I fixed something another issue developed.  Certain parts no longer available so work arounds have to be performed.  The bike runs well, however a BMW tech reported idle speed a little rough, like the intake has air leaks from o-ring failure or flange warpage.  According to them(BMW) it is a 5 hour job(including fuel line replacement)for a wheel barrow of money. I never noticed any rough idling with the motor. I had the electrical issue because Bulb Monitor relay was bad, no longer available, so I had a shop do a work around.  Brake lines were ready to go so I replaced all of them last month, time to do the fuel lines as well.  Earlier this year I had brake light not working, got it fixed, then brake light stayed on forever after changing out brake lines, switch is cooked probably, only $50, the state inspection is current, however I went and bought a BMW R1200RT so I am going to sell this bike.  Will list it at BMWOA also.

You've just stated the major reason sites like Motobrick.com and the K100-Forum exist—mutual support to defend against the cost of institutional repair outfits. BMW dealership technicians tend to be unfamiliar with the quirks of classic Bricks and could be tempted to throw parts at one until it's rehabilitated. The concepts of "flange warpage" and barrels of money are indicators.

You are correct in the understanding of my last post, nevertheless the bike will be exiting stage left.
