The leak seems to be from a crack in the speedo cable in the front and some black fluid is slowly coming out. What is this fluid? Easy to repair?? Major Concern?

The speedometer still works. Just wondering what the fluid is coming out of line. Is this a problem? Does this have anything to do with the Hub grease?

It's speedometer fluid that's leaked down through the cable. A drop or two shouldn't be a big deal, but if the needle starts to bounce, you should top it up, or flush and replace it if it's never been done.

Thank you. Since the black sheathing is cracked, I have put electrical tape temporarily. Should I replace cable, sheathing, might as well replace plastic gear too. Do you sell this stuff?

Dumb question... this has nothing to do with hub grease or anything right? So nothing to really worry about immediately?

He's messing with you!

A crack in the speedo cable shouldn't be a big deal. Do the speedometer and odometer still work fine?

My cable had a crack in it at the headset end. I used it that way for a couple of seasons, and replaced the cable when it finally broke and my speedo stopped working - it was kind of a pain, requiring removal of body panels and finicky cable routing.

Have you ever greased that speedometer cable? It should be done every few thousand miles. Service Intervals After a while, the grease gets black and gummy - that could be what you see coming out of the crack?

Jokes on me Crying or Very sad emoticon

yes everything is still working fine. Vespa only has 3500 miles so maybe I can hold off greasing right away.

Funny part is I asked my neighbor who is a Harley guy and he was telling me I had to immediately fix that before it dries out the wheel bearings... silly HD riders...

+1 on what Berto said.

My speedo was bouncing pretty badly. I removed the inside cable for cleaning, it was full of black gritty gunk.

Well, if it ain't broke...

But then again, the bike (and grease) is 15 years old, so extra attention wouldn't hurt it!

Nothing black coming out of anywhere on any vehicle is a good thing. That being said it is only the speedo cable.

Good fix with the electrical tape.

If you have the wherewithal clean the inner cable and re-grease it. If not don't worry until next time you get the oil changed or something and ask them to clean and re-grease then.

That doesn't sound right. Do they always fail at the same point?

Is the cable routed correctly? Maybe it's pinched or has an overly-tight bend somewhere?

Tape will be fine, maybe heat shrink tubing for something a bit more permanent.

Just installed my 4th cable today at 24,000 miles. The first 3 lasted for about 8,000 miles each. I think it's the bumpy roads we have in New York. The constant flexing of the cable causes it to crack then the inner cable breaks.

How do you wire it correctly? Can you take of your fender for me from the inside?

I had some cracks in my speedo cable and sealed it up again with some black silicone sealant. Been good for a couple of years now.
