I have a 1988 k100lt with 140k miles. Purchased from a bmw mechanic in brooklyn. Mechanically the bike is great and had never had any electrical problems to the previous owner.
I have been riding the bike for a little over a month. A few gremlins I've encountered :
Sometimes the cooling fan cycles on/off with the blinker.
Sometimes when i turn the ignition and pull the brake the lights go dim on the instrument cluster and the bike will not start until ignition is switched over again.
Taking the bike on a road trip from ny to al i noticed that sometimes a loss of power would occur around 4k rpms or 3/4 throttle. Pulling the clutch the engine would rev past 4k fine but in any gear the power was lost. Restating the bike would fix this for a couple hours.
Made it 1000 miles to alabama.
I was heading back to ny through Atlanta and all the sudden i noticed that the tachometer/speedometer wasnt working, and the battery light was on. I pulled the clutch to restart the bike and nothing, no dummy lights... Blinkers, horn, headlight and brakes all work. So i pushed the bike off to get it off the interstate. Pulled to the nearest gas station and as i was using my blinker to turn, trying to cancel the light, smoke came pouring out of the right hand controls and from under the gas tank. Shut it off... walked it to a stop and checked the wiring. Lots of stuff fried on the right hand control connection, all the way up to the wiring for the fuel and fan cluster.
Cant believe it.
Not really sure where to go from here.
