Speedometer

Post by Ptatsoc »



I have a resurrected 81 GL1100 finally have it up and running have put the first 200 miles on it. The speedometer took a dump started bouncing around and then stopped at Zero not even driving the odometer. Cable is good, drove speedometer with a drill and nothing happens. Is there a way to resurrect these. The other question is can I use a speedometer off of say a 750 will they work. Flee bay currently only has 2 speedometers listed for GL1100 and the asking price is way high.

I replaced the one on my 82 with one from an 83. the 85 mph one probably got oversped and took a dump before I got it though the odometer still worked. but the 83 version was a 140 mph unit so no danger of over stretching it. just in case it will help.

Was able to open up the speedometer carefully pealed back the chrome ring and separated the top and bottom, the bottom was full of goop Soaked the bottom halve in MMO overnight. Put just enough in to cover the input drive from the inside. Was able to work the input shaft loose in the morning and seems to be free. Works when connected to the tach cable for now. Will see if it lasts.

Keep us up to date. My 83 isn't currently working and I'm planning to open it up sometime soon. Over the years I've learned that the cable often drives a dynamo which creates an electrical signal which the dial uses to move and have had good luck using rubbing alcohol to clean things up and silicon grease on the gears.
I'm selling good clean fresh hay. If you want some that's already passed through the horse, that comes a little cheaper!

The best advice on internet motorcycle repair forums comes from posting the wrong answer to your own question.

Well just did a 50 mile run at 75 to 85, that just barely keeps up with traffic here in TX, Speedometer and Tach both ran solid and smooth the whole run. Temp gage on the other hand need to trouble shoot went from 3/4 to 0 just after the turn around point, fuel gage working just fine so 7v thing is working, hopefully just a loose wire.

check the connection at the temp sending unit. other than that, it could be any of the connections, a bad wire, or even a bad gauge itself.

Apparently when I put the cooling system back together after replacing the radiator, thermostat and the connecting tube o rings I disconnected the darn wire for the temp sensor it was not snapped onto the sensor just hanging there.
