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.

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.

Bumping this old thread. I was having the indicator issue...I cleaned out the sensor and all is well.

However question, is a small amount of oil in the sensor area normal? Did you guys also find some engine oil in there?
When I cleaned out it wasn't an active leak nothing further dripping. Just not sure how it gets in there and if it is normal or should I be worried about some worn seal somewhere?

I've just noticed mine being slow to respond also. Guess I need to get the manual & find that sensor.

Sounds like an easy fix though!  :)

I just cleaned mine, a simple 15 minute job. Don't do like me & spend a bunch of time looking in the transmission section of manual for location.  :-[ It's in the electrical section.

I used long handled needle nose pliers to pull it out. The 2 brass pins in the bike are spring loaded & will jump out. I didn't realize there was supposed to be one in the center hole until I reassembled it & saw it on the floor. So watch for it.

I see Greg has found it, but here are some pictures anyway.

Last picture is after cleaning.

I have not taken mine apart yet, but thanks for the brass pins and the spring loaded part. Good to know.

Good pics, thanks!

Regarding the small oil leak when cleaning, I learned to clean mine while changing the oil.  Any oil that might come out has most likely already drained by that point, but if not you'll catch it in the drain pan.  Also gives me something to do while waiting for the oil to drain completely.
