Took this picture at a BMW meet long ago. How long ago? Well, I had to go to Walgreens to get the film developed. The meet was in Kentucky or W. Virginia as I recall. Creative rancher/farmer bodywork.

I found a knob and a clock.  $60+shipping.  I still need to go through my collection of stainless to put together a usable collection of hardware.

Thanks for the suggestion, fuel pressure is steady hot/cold/rich/lean though. Fuel filter was a brand new, quality item fitted by me when I got the bike & tank was previously de-tarred/resealed & had new pump, lines and isolator. 

Good thought though, appreciate the input. I've seen that on cars also, usually accompanied by a "whoosh" of air being drawn in when opening the cap. 

At this point I'm not sure what I'm saying myself, except for the fact that it currently runs* as well as it's ever done in my ownership & due to other 4-wheeled eye candy occurring I'm pretty well donezo with the thing and may let it go to free up some funds if anyone's daft enough to buy it!

My thoughts would be that it was a coincidence. Yes the speedo and odo use the same electrical pulse, but it splits inside the cluster so one would not have any effect on the other. Even if the odo totally stops, it should have zero effect on the speedo.
If both stopped, I'd look for a loose/dirty electrical connection.

Perhaps rotating the knob stem overcame possible obstructive schmutz between the gear teeth or oxidation in the connection to, and within, the gear motor.

Ok So newly acquired Brick;1990 k75 ; was missing trip reset dial...So I got the needle nose pliers and spun that sucker around...IT Works!...suddenly, the speedo AND odometer stopped working for about 3 miles. just as suddenly she came to life...Qustion: What correlation could spinning the dial have with the electric pulses to speedometer. PS the guy probably REMOVED the dial!

Caveman, it'd be awesome to see you, and catch up. Count on us for a stay, recharge, or just a quick shower and go. I've got a cousin under the wing all July, so "help" is available for hammer swinging, etc. Message sent to your box. Cheers

I think you're saying that it runs ok, but then when the engine gets warm it goes lean, I guess that might mean about ten minutes after start up. Even if I've interpreted this right, my guess is still unlikely, but it's such a quick and simple thing to check.

This reminds me of a problem I've seen on cars in the past. Start it up and wait for it to go lean, then pop the fuel tank cap open. If the problem then disappears, one possibility is that the fuel filter is lousy, but you replaced that, goodo. Another possibility is that the fuel tank vent is blocked.
