My speedometer is off by about 15km/hour. If I want to fix it, do I need new speedometer gauge, or would a new cable fix it?
If it's a new gauge I think I'm going to just live with it for the time being.

If the cable is sticking/binding it could make the speedometer be off. Does the needle flutter? Also did, you change the front tire size? You might try lubing the cable.

It definitely flutters. I thought that was just due to it being an old bike.

Oh, and no I'm running a stock front tire.
I'll try lubing it before buying any new parts.

Well, lubing the speedometer cable was one of the things that I did over the winter and now it flutters a lot more.
What does this usually indicate?

I had similar results with my '79. I went through it, lubing everything I could -- speedo needle jumping got worse after lubricating the cable (I did, however, use wheel bearing grease on the cable length, not a liquid lubricant, as specified by the book -- discovered my mistake long after I did it, didn't feel like taking it off and re-doing it). My speedo is over by 9 MPH at 55 (which is actually only 46 MPH... 80 on the clock, is an actual speed of roughly 69-70 MPH) -- this did not change after my mis-lube job. On my Voyager, there is a plastic gear in the wheel: if it loses a tooth (common failure...), the speedo will be off by 5-9 MPH. Could be a similar issue on the Honda's.
I checked into having my speedo repaired, but the company I found (which claimed in their ad to be capable of fixing 'any' speedo...) told me it was too old, no parts. Use a GPS to gauge your speedo's margin of error: check speed on the GPS, and the speedo, to find out what you need to aim for, at common speeds, such as in-town, and highway. Your speedo will be off by a percentage, not a fixed number of KPH's, so as you climb in speed, the KPH difference will increase, between clock, and actual (GPS). Be careful while doing this, as you will need to take your eyes off the road to read the gauges... Cheers!

Thanks for the insight sarge. I used specific cable lube that I picked up at the honda dealer while I was getting some other parts a while ago.
Anyone have any tips on the jumping? It was pretty much unusable it was jumping so much.
I thought it might be slipping, so I tried screwing it in tighter to see if that helps.
If that doesn't work, does anyone know of a way to fix it? Do I need to pony up and buy a new speedo?
Judging by the cost of things on ebay (seem to go for about $100, plus the ~$30 it would take to ship it to Canada) I am thinking I might just get something different and better looking from Carpy or another place.

I've done a little research and read the FSM and it seems there is a chance that it's the speedometer gear that is on the front wheel, or the cable itself could have snapped or partially broken. I'll check into this fairly soon.

My speedo does ok,but my tach jumps real bad anywhere above 6-6500. The faster I am accelerating the harder it jumps. Wasn't trying to hi-jack,figured it might be related issues.

Sounds like kinked cables cause jumping so I'd inspect it and maybe a replacement cable would fix it if it annoys you. Sent from my BlackBerry device on the Rogers Wireless Network

I figured this out. My front axle was loose causing the speedometer to not seat properly.
I took pics so I'll post a write up in the how-to section.
