Re: left blinker not working.....'85 k100
I am not 100% sure but I believe the flasher is common for both turn signals so this might cause the problem. On my 85K the left turn would would intermittantly work but it never effected the right. I found that the connector for the switch under the fuel tank was loose. I have read multiple posts that these old bikes are susceptable to the connections getting corroded and also wires breaking do to age. May want to follow the wires down from the left turn switch to the connector under the tank. Mine has a clear plastic cover over the connector which makes it difficult to take apart and reassemble. While you have the tank off look at the ground lug on the left side of the back bone just behind the steering head. These also can corrode over time causing wierd problems.
I personnaly find that intermittant electrcal problems are the worst thing to diagnose.
