Too long speedometer cable causing bouncing needle?

[klemmy]

Anyone had simmilar issues?

I'm having bouncing needle in the speedometer since i own my ETZ 250. I had tried many things, lubed the wire, lubed driving mechanism in the rear wheel, adjusting cable to have the "smoothest" position to run...I put a new (used) speedometer, it is the same situation, the needle is bouncing up to 70-90km/H beyond that is ok. I tested speedometer with cordless drill and it picked up speed very smoothly and without any bouncing. But when I disconected cable from driving mechanism and drive it with cordless drill ,it is bouncing again. So I think there is a problem in the cable.

The cable itself is looking pretty new...

Any suggestions? Shound I trimmed the end of the cable, the square one?

Thank you very much for your answers

bur on cable it binds an releases giving false reading

MZs speedos at best aren't super accurate. I use a magnetic bike speedo alongside the normal speedo (called cateye quick) for a spot-on reading hence reassurance in these days of 20 limits.
It's small discreet and easy fit. They cost £30. Downside: goes haywire above 53mph and not back-lit.

they make GPS units for boats but most only show to 60 mph and do not display miles traveled

but looks like amazon has a bunch of listings

Problem solved.

It turned out, that the cable was problem at the end of ballade...

New better quality cable is fitted and now it works fine
