Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Speedo stopped working

Post by Pugzilla on Mon 26 Jan 2015, 7:05 pm

Just noticed on my commute home that my speedo and odometer aren't working. Tacho is working fine.

From googling it, it seems that the speedo cable might be the culprit, how do I confirm this?

Where's the best place online to order a new one?

It will either be the cable or speedo drive. Unscrew the bolt that holds the cable on the front wheel and look at the end of the cable- either the end will be snapped off or a bit of the speedo drive will have snapped. Get a genuine honda cable from david silver or lings because I had a pattern one break in under 6k miles.

Looks like the speedo cable has snapped. Was able to pull a 3 cm segment of it from the tubing.

Not uncommon, I've had two snap on me over the years.

It does happen (as you've seen), it happened to me - I got a cheapo replacement from ebay, so far it is still working.

On quite a lot of speedo cables you can remove the inner from the outer (so to speak). IF you can do this on the replacement one you buy it might be worth greasing it up before putting it into service. If you can't remove the inner then a good spray of chain lube or grease spray (or oil from a can) down the inside isn't a bad idea.

Ancient folklore has it that you shouldn't grease the top two inches or so of the cable (to stop grease getting into the speedo) - personally I have never seen a speedo where it would have been possible for grease from the cable to get into the speedo, but I thought you should know Wink

Will I able be to disconnect the old cable from under the speedo without removing the fairing?

I *think* you need to remove the fairing, but I haven't got a CB500S so I could be wrong.

Someone else that actually *knows* will be along in a minute or two....

I was able to replace the old cable without removing the fairing after all.
A bit awkward though. If you have big hands, it might not be possible.

Thanks for all the advice
