Speedo trouble.

Ok folks, I'm perfectly happy to admit I might be doing something wrong here...


...because for the life of me I can't get my SR125 speedo working.


When I acquired it, the needle worked but it used to jump about and wasn't steady. Now it's died completely.


I've tried 3 cables and 2 speedo drives and can't fathom why it isn't working.


Anyone got any ideas???

Connection into the clock itself? That went south on my Lexmoto (lol Chinese bikes) and I ended up having to replace the entire unit.

I was thinking this But hoping I was installing the cable wrong or something...

Yeah, hopefully not - new clocks are rarely a cheap option.

Dare I say it - couldn't you just download a GPS speedo app for your phone and clip it to the bars, and say "f**k it"? I've resorted to that on more than one occasion :lol:

Disconnect from front hub and try an electric drill on the end of the cable to see if the speedo moves.


Similarly disconnect from the speedo end, spin the front wheel to see if the speedo end of the cable moves.

For some awful reason I was expecting a different issue altogether:

That's lowered the tone. :roll:

 

Yeah that was a bit weird... :|


Moving on...


Oli - I've actually had this issue for a couple of months now but I want to get the bike to 100k miles and how will I ever know I've hit my target without the odometer reading! :) been playing the guessing game with speed cameras for about 3k miles, so far still clean :lol:


Joe - cheers. Will try that - assuming it doesn't make the needle move, diagnosis will prove the dash then?

there is 4 failure points on your speedo and its just a process of elimination


clocks, cable, drive at the wheel and the drive on the wheel


you can test the cable by disconnecting each end and spinning it and see if the other end turns make sure you give each end a tug too to make sure its not split although with you saying that cable is new I dont think it will be your problem


if the cable is fine then move on to the clocks ... attach the cable and use the drill method


you can check the wheel end by attaching the cable and leaving the clocks end off and spinning the wheel


doing all of that will point you in the right direction
