I have a 1987 Honda CBR 600, I bought the bike used. The Speedo works, but i think it is off, the RPM's works, but the Odometer doesnt work, the trip doesnt work and the Temperature guage always reads 1/2, even at cold start up.
Is there a way to fix the odometer, trip and temp gauge without replacing the whole cluster?

 

Kind of a vague question, but it sounds like you have multiple issues within the same cluster. I don't think they would be attributed to one thing, and you more than likely have several different things causing the issues. Without tearing into the cluster, you won't know what the problems are. They wil surely be internal.

If it were me and my cluster had all of those issues, I would check into a new cluster, or a used on on ebay.

the one thing that may be wrong with the temp gauge is the sending unit. make sure its hooked up. If it is, you may want to test it.

 

check the connections in the back and make sure they are clean.

 

Does the 87 CBR have a seperate odometer cable? I saw one forsale on ebay. Where would I find drawings or schematics for the cluster?

cheers with gears

 

it doesn't have a seperate cable. its pretty easy to get inside to the workings of the speedo. there is probably a gear on a shaft that came loose. i've reglued odometer gears on my cars speedometer before.
i have a spare speedometer, and temp gauge if you're interested.

 

I took the instrument cluster apart, noticed on the speedometer that it looks like there is a gear missing, is there a gear that goes on the speedometer and attaches to the odometer gear? It seems like there should be one.
How much are you asking for the speedometer?
Thanks

 

are you interested in selling the speedo
