TECHNICAL MOTOBRICK WRENCHING In Remembrance of Inge K. => The Motobrick Workshop => Topic started by: awshucks on October 17, 2011, 06:19:16 PM

Ever since spline lube early summer on '85 K100 RS, my speedo occasionally wouldn't start working w/o a finger nail few taps on the glass/plastic face.
This w/e, I was cruising long at about 60 indicated, looked down and the needle was at 0. I tapped the side of housing w/ a pocket knife, still at 60 and it started working again.
Any guesses what/how much this one will be?

Also check the wiring harness connector for it.

Thanks, just what I needed. ;D

I'd definitely start with the 2 wire connector coming from the speedo's sensor. It's happened to me before that I unplugged it, plugged it back in and got the same symptoms you have now. Do that again, maybe clean the contacts up this time, and it may just fix itself-- like mine.

greetings awshucks...
speedo only or odo too...

Not 100% sure, but think odo goes at same time. I'll have to check it out in a.m. if it acts up.
-
everytime i would wash the bug or ride in the rain my speedo n odo would run slow for days n sometime weeks... then all of a sudden it would be ok...
i always thought it was the sensor wire cause both ran slow....
-
Gee, How time flys! I wanted to let y'all know, it appears to have been a little crap on speedo pickup in final drive. I'm several excursions w/ it, and no more problems, knock on wood. Thanks for the help!
-
Good to hear. And it's always nice when people come back and update tech threads. Thanks.

you know you can chrisschross the sensor wires n run the odo backwards...

Lol, honestly didn't know that, but suspect PO may have!

I just ride down hills backwards.

LOl, better man than me! Speaking of hills, my gravel drive goes up while doing a 180 degree turn. I could handle it easily on airhead, but K w/ higher center of gravity was a thrill, even w/o washouts from rain.
I had a 30" by 5" deep sidewalk dugout and poured in middle of it, all 403". At first it was like trying to keep the bike on a railroad track. ;D This is the easy part, two more curves, the last a sharp 90.

So why do you suppose tapping the speedo face worked if it was the sensor? May still have a flakey connection in the instrument pod, sometimes they go dormant depending on moon phases.
-
Good question, haven't a clue. It was light/white colored non-magnetic right on what I assume was the magnet, may have jiggled around there?
I know, wishful thinking, I so don't want to have to tear into this, lol.

Did a 500 miler this w/e, tap tap tap. Trip goes out w/ speedo, didn't check odo, but would guess it does too. I got 40 mpg two up [w/ kid].
Will have to address this sooner than later, idiot lights for 7L and 3L are a joke. I need that trip odo.
