Instrument repair

[Lawrence]

This weekend is to be my first opportunity to get up close and personal with my new-to-me 1985 R100RS.  I aim to change the fluids and sort the malfunctioning speedo/odo.  I warmed her up and while the crankcase was draining, I had a look and the instrument pod. It seems to be straightforward: remove two 10mm bolts and then separate the cable connector at the rear.  But noooooo.  :-\ I removed the two nuts, but its impossible to withdraw the bolts which seems necessary to free the instrument pod!  What am I missing here? How does one separate the instrument pod from the bracket that secures it to the fork yoke?

Four allen head screws on the rearside of the instrument pod secures it to the bracket.

Just know that if the speedo/odo doesn't work, the problem is most likely either the electrical connector for the speed sensor (under your right knee), or the sensor itself. Take the sensor out and clean it off. Make sure there's not oxydation etc. in the connector.

And follow the wire between the two.  Mine quit because the wire was rubbing against the rear tire!

The signal pickup in the rear seemed to be fine, and cleaning it had no effect on the speedo.  I did resolve the problem after I cleaned the connectors on the back and interior of the instrument pod, and the one near the right sidecover.  I'm happy to say I now have a working speedo/odo.   ;D
