1 I have now officially decided that my odometer problem is "gremlins" Wed Oct 16, 2013 3:31 am

So, here's the thing. We have two K100RS - one 1984, one 1985. Mine is Hermann. Hers is Helga.
Hermann had the intermittent speedo problem first. I opened the unit, and found that a previous owner had butchered it - the circuit board with three prongs on it, at the top, had been cut through and shabbily soldered back together during a filthy attempt to mount the supporting piece of white plastic to the speedo unit. There were other problems, including connections becoming unstuck.
Eventually, I gave up when the speedo stopped working entirely, and got a second-hand unit. Eventually, that one developed the intermittent speedo problem as well. This time, the insides were clean and virginal. I very, very carefully cut through the supporting arm and remounted it to the speedo unit, while gently twisting the pins, thereby completely curing the intermittency and giving me an ultra-reliable speedo again.
Then, there is Helga. Helga, which is in excellent condition, had the intermittent speedo problem for a while. My partner didn't care. She is amazingly good at judging speed, and anyway, when we ride in a group, she always gets me to lead, so it didn't really matter as much. But, having fixed Hermann properly, I changed the mounting arm and now it's reliable.
But Helga's odometer stopped turning This is much more of a nuisance, for reasons including mileage and judging fuel. My first attempt involving examining the gears - they all appear to be clean, apparently unworn and completely intact. I turned them with a screwdriver - the numbers moved. I put it back on the bike, and ran it carefully in top gear on the centre stand (yes, I took an awful lot of precautions) - the numbers moved. The odometer worked!
She took it for a ride. The odometer did not work. I tried again, this time examining all the connections and gently twisting the pins so the contact was better. The odometer worked precisely once. The second test - no dice.
At this point, my question is: Who in Brisbane is the best person to fix this? I don't like electrical things. They and I don't get along.
