I replaced the air filter in my K1100LT. That took an hour because I couldn't remove the right fairing due to there being a sidecar frame in the way. I had to rotate the fairing out of the way enough to squeeze a hand back there to get the front clip out. Eventually got it done. Over the winter and spring I also replaced the fork springs, bushings, seals, and oil. I also rebuilt both front brake calipers with new seals, brake lines (Spiegler) and pads. I put a new front tire on, changed the fuel filter, and changed the engine, transmission, and final drive oils. Finally, I also rewired the side car and rebuilt the sidecar side marker light and tail light with LEDs.
