Would you please help me with the gap for the set screw that presses up against the shaft that holds the odometer gears? It's the white nylon screw that touches up against the the steel shaft with the odometer's gears. In the attached picture there is a red circle around the area.

In my last adventure going in this deep, I didn't pay attention to the gap. When my odometer hit 61,999 miles, it got stuck and would not roll over. This also kept the trip meter from functioning.

Before I put it back together, I'd like to go on more than a guess for the gap.

Thanks. odometer set screw gap? K100_o10

Ricardo Palao helped me, suggesting a gap of 2mm, on the FaceBook group "BMW-K  motorcycles K1 k75  k100  k1100 (purists)". I've put around 250 miles on it since reassembling with that tolerance, and it's working great.

Having had a look at a couple of mine, my guess is that the screw is only there on the very early speedos where it's possible to remove the spindle - it prevents the spindle from migrating across and dropping the drums. On the later speedos the other (non-screw) end of the spindle is crushed to prevent it from being pulled out. I haven't seen that screw in the later speedos.

Disclaimer: I've only dismantled around six speedos in total and those were my findings.
