Are you sure the cable is broken?

It is easy enough to put the new cable in, leave your old cable in and put the new one alongside it. Then take out the old cable.

Easy enough to do. Remember to grease the cable up too!

You need to make sure that the cable is pushed home at both ends, at the speedo and the gear on the wheel. If it is, it could be a problem with the gear on the front wheel.

What I have to do with the.wheel??? cable is fit good

As you look at the bike, on the right hand side of the front wheel, you have the speedo drive gear. You need to make sure the speedo cable is pushed into this properly.

It usually snaps the inner cable inside just above where it comes out from the fixing at the front wheel, diconnect it there and pull the inner cable ,see if its broken

i am polish :( i have no idea what you talking about, what the f.. is inner cable?

The speedo cable is a thin twisted wire (something like the stuff your mum may have used to hang net curtains) inside an armoured sheath.
If you unscrew the cable at the front wheel, you can usually draw the cable out from the sheath and feed the new one back in...unless it's broken and you can only get part of it out.

You have the whole thing (cable and sheath), so it's just a matter of screwing it in at both ends and using the same clips the old one used.

Have you found the problem Tom?

replacing a full speedo cable (inner and outer) is really easy, though I had to learn the hard way....

take the screen out the the surround that goes around the clocks. takes a bit of careful jiggery pokery to get it out but do that, then you can easily access the top part of the speedo cable so you only then need to unscrew it at both end s and carefully remove the cable from the clips that hold the cable in place on the inside of the front fairing.. just follow the cable up with your hands from the front wheel and you'll feel the clips.

another way to see if the cable is broken, get a drill, detatch the bottom end of the speedo cable from the front wheel drive and get the inner metal part of the speedo cable secured into the drill and give it a gentle whizz.
if the speedo moves off the stop you know its not the speedo cable but the speedo drive.

if it is the speedo drive, its likle that the plastic hub inside the speedo drive has worn. I had this coming back from bigmac last year. yamahas original part is shitty plastic that wears. mine had done 41,000 miles and a replacement is pretty cheap and is made of metal so much harder wearing.

hopefully some of that is useful to you

Tom, the test is quite easy.

There are 4 parts to the speedo. The display, the cable, the pickup drive and the 'clutch meter'.

As Mr Nutt said, use a drill - have your wife look at the speedo while you are doing the test. The needle should move, also check the mileage numbers (Odo) if they move, could be they are moving backwards. This will mean the cable and speedo are OK.

I have gone through a few pick up drives and clutch meters and I do think this is where your problem is. It will need a front paddock stand and the wheel taking off, so getting someone to do this for you will be a good idea.
There are two parts in the front wheel, one is the pickup drive, that is the unit you screw the speedo cable into - the original drives had a nylon worm gear in them, the replacement units are made with a brass gear (I have managed to wear out both types). The cheapset part is the clutch meter, which is a washer with two raised tabs and two ears. this part tends to get bashed when the front wheel is removed when the tyre is replaced.

Tom the work really isn't hard at allay worst you'll not have a working speedo if it goes wrong but as Steve explained in some great detail there for you, it's really really simple to do, changing over the entire set if fairings is probably harder than doing this.
If you need any more help just ask
