Does cleaning the gear position sensor ever work?
« on: June 13, 2019, 11:32:07 am »
My gear position indicator has been acting up recently - slow to respond to gear changes and sometimes not indicating the right gear.  I did the sensor test of pulling the clutch lever in while the bike is in OD but the indicator still shows 5, and the indicator changed to OD.  So it appears the sensor is the problem.

Has anyone restored sensor functionality just cleaning it?  If so, what did you use to clean it, and were you able to do so without completely disconnecting it and the two wiring harnesses?

Yes - mine was similar some time ago.  I cleaned the contacts with very fine emery.  2 screws to remove from contacts on the end of selector drum.
The best substitute for brains is ..............what?

Freddy - Just saw your post.  I hadn't heard back from anyone so went ahead and just removed the sensor (but not the other two connections) and wiped it and the the two pins in the shifter drum real good with a soft cloth.  Took it for a 50 mile ride and all is well!  It showed the correct gear with every shift and there was no latency. 

If the problem returns though I'll try cleaning with a very fine emery cloth or very fine steel wool.
