Speedo not working

[Bonzodave]

hi just bought a 2000 model 600 fazer and the speedo only seems to be working now and then, and starts jumping up and down even when I'm stood still, The tacho is fine and isn't giving me any error codes, can anyone help?

It is more than likely the speedo sensor has been damaged. There are two tabs which are prone to failure on a ring fitted in the front wheel - plenty of threads covering repair and replacement in the 600 section

Cheers dude I'll have a look

If it's jumping up and down when the bikes stood still,
It won't be the speedo rotor which is the part that the tabs break off from.
Sounds more electrical,
I'd start checking for loose connections and frayed or damaged wires

Definitly speedo, and not rev counter?
