I just picked up my bike (zx6r) from the dealer, I was having speedo problems. It was
way overestimating my speed, for instance if I was going down a local block
doing no more than 20 mph my speedo would indicate 50mph. The faster I went
the bigger the error.

The dealer ordered a new speedo unit, I looked over my bike and saw that they
didn't test ride it becasue the speedo had 0 miles and the trip had 0 as well.

As soon as I rode it down the street I immediatly knew the problem wasn't
fixed. My speedo indicated I was going 20 mph while I was barly doing 5mph

What can cause this? I have a spanking new speedo (thank the lord for an
extended warranty - the bill was $570) I checked the speedo sensor and the wires are all connected.
And its not exclusive to the speedo, the tach is sometimes off..

any ideas?
Cluth slippage
Chain / sprocket wear?

I don't want to bring it back to the dealer just yet. If I have to I will but
I have a feeling they will be asking the same questions

Thanks
Dave

THe speedo pickup is down on the front sprocket cover. Is that intact? it should be some sort of magnetic pick up that recognises how fast the chain is turning. Make sure the hole on the back of the sprocket cover isnt jammed with gook and grease.

And did ya go to a smaller front sprocket? Might no be able to pick it up as easily since the chain is now slightly lower in its rotation circle.

But if the tach is messing up too, then Id suspect something that controled both. ie. computer.


98 6R. TBR slip-on. No poser add-ons.

i vote for contacting kawasaki directly, i mean whats the worse they can say? "talk to your dealer", they could probley give you more help than a dealer can anyways. if they do tell you to go to a dealer, try and find one thats in the area that is worth dealing with.

you could also check the wiring down in the engine, there might a short or something; but also might be the computer.
