Odometer and trip meter

[TomInLosAngeles]

Hi -- I bought my 84 Cb700SC on Saturday, and here is my first question.  The bike is great (tons of fun and speed, love the look of it and I'll post a pic once I get the tuneup done and the thing back together).  I have already read the info on turn signal options (I currently have these tiny little aftermarket things that don't fit the rest of the styling at all) and wonder what anyone did with this kind of thing before forums like this one!

the first of MANY questions for the knowledge base of the forum is:
The odometer sort-of works.  If I ride ten miles, the odo ticks over maybe one mile.  The trip meter works as it should (ten miles registers as ten miles).  Any suggestions?  I think it means that the cable is fine, and the issue is with the odometer.  Are they replacable?  Or fixable?

The current odo is 19000, but who knows how many miles are really on the bike.  It needs some TLC (hand painted tank, oil leak from the shifter seal, fuel gauge, hazy plasitc screen in the fairing) but nothing too major.  I bought it two hours from my house and had a blast riding it home.

Any suggestions re: odometer appreciated.
Thanks
Tom

Yeah, it sounds like your odometer is messed up. I'm not sure if you could change just that or not. Would probably be easier to swap out the speedometer gauge with a used one. You could also clean-up your gauge lens at the same time.

Thanks for the quick reply.  I was kind of hoping you'd tell me to squirt some WD40 in there and I'd be right as rain.

Are the speedos available?  Since I bought the bike I've been on this forum and cruising the web and parts for the SC seems few and far between.  I am assuming that there is a lot of interchange between, for example, the 650 and other Honda's from the era.

700 parts only fit 700's as far as I know. Maybe a few incidentals, but nothing major is interchangeable.

There are some tutorials online about rebuilding odometers.  You'd have to search for them.  I don't have the links anymore.  There's a guy in SF who does this as a side job.  I took the odometer from my 78 CB400 to him.  Great guy.  It turns out my problem was elsewhere, but he did what he could, and cleaned it up, and put it back together.  I would recommend him.  I'll give you his info offline if you'd like.

You can squirt some WD40 up inside after removing the drive cable.  It won't hurt and may help.

I had a speedometer that made a bunch of noise.  I thought it was the front wheel bearings, but not.
I went to the extreme with WD40!
I sprayed WD40 all inside the speedometer, including through the holes that the light bulbs fit.
There was liquid WD40 inside the speedometer.... and the noise quit.  The speedometer worked well or better.
The WD40 did leave an oily film on the face of the speedometer, but it was almost invisible.

Later I was told that spraying lubricant up the drive hole would have been sufficient.

Ride safely,
