Keep your bike maintained and serviced and don't worry about finding someplace to get it repaired. I used to race in my misspent youth and it taught me the value of diligent maintenance and preparation. Maintain your ride and use it regularly and you will have no problems. Make sure all your electrical connections and the fuel system are clean. With your '85 K100 I would suggest replacing your ignition coils with later models for more reliability.
I carry the factory tool kit along with a set of Harbor Freight ball end Allen wrenches, a 4in1 screwdriver, and a set of 1/4" drive sockets. A tire kit and a 12v compressor will handle tire problems. I have a tablet with the factory repair manual on it.
I carry a few spares: a clutch cable, HES plate, some fuses and a couple relays. My K75RT horizon chaser has 100,000 miles now, and I
nothing of doing 7-8,000 miles on a trip. So far, I have only had to replace a couple worn out tires and add some oil to the engine. When I am all alone out in the middle of nowhere after dark my only concern is whether or not I have enough fuel to make the next gas station.
Last, being from California, as long as you don't break down in Oregon or Washington, U-Haul will probably pay you take one of their trucks back to Cali with your bike on it.
