there's a saying.. that after pleasure come's pain, well that's bloody true :sad: after having a brillant time in the cotswolds with the gang, I decided to remove my rear wheel and fit the new tyre I just purchased, so took the tyre into our workshop and asked the tyre fitted who changes all of our motorcycle tyres to change the tyre. I know the tyre sensors are fragile so made him awear of this, you don't break the bead by the valve, don't remove the valve core, just let the air out by pressing the centre core! anyway, don't know what happened but when the tyre was removed the sensor was loose in the tyre, it had snap from stem. don't know how it happend. it's possible he caught the sensor with the tyre lever or when breaking the "bead" may have shocked it? anyway, this has been the most expensive tyre I've ever changed. here is a picture of the broken sensor and the cost to have replaced. needless to say I'm well pissed of with my-self, so I needed to fit a standard valve just to get the tyre on, so I can re-fit the wheel so I can get the bike to the dealers, so they can fit the new sensor and re-program the e.c.u with the new sensor. and to rub salt in the wound, my significant other half "my darling wife" said.. serves you right, for being trying to save a few bob, then said the obvious... if you had taken it to the dealer and it happened they would need to put it right. well I've warned her to sleep with one eye open tonight. :laugh: well if I never, I would :cry:

replacement sensor £165.00
remove the rear wheel and tyre and re-fit £25.00
re-program the new sensor £30.00
total cost £220.00 plus the tyre which was £122.40
TOTAL.. £342.40 :angry: :sad: :hammer: :hammer: :cry: :cry: :cry: and double :shit:
Bugger :sad: Unlucky mate.
Forgive me if this is a daft question but does it affect the bike in any way if the sensors are not replaced ?
Dave, what the hell were you thinking????
Ouch! Sorry to hear that. I feel your pain.
well steve.. that's just it, I wasn't thinking..!!

No. You just don't get any value on the display when on TPS mode.

well that's simple my mate..! the buggers don't work :laugh: well you got to :laugh: or you would :cry: if the sensor is not replaced it will show the fault warning on your lead display and most likley will stay on, which would be as bad the wife moaning at us all the time :smiley: I'm not sure if you can by-pass this. however, having tyre sensors that don't work is like having a dog and barking yourself. so I will need to bite the bullet, call myself everything under the sun for being a "tight arse" thinking I will be saving a few bob, and put this down to experience. like the wife said before, when I was walking around the house with a right "GOB" on me.. it's no use :cry: ing over spilt milk :hammer: :hammer:
sorry to see that Dave....the power of hindsight and all that mate
- your wife sounds damn familiar ...

happened to me the other week, the sensor was snapped away from the valve part, so the sensor its self was ok, kawa do a valve only replace part for £40 v the £180 for the full lot. My tyre guy found a vlave from a car that was almost the same fit and its fine after 3k miles
From now on I am going to put two strips of masking tape on the wheel to highlight where the TPS sensor is.
I bet they still f up

nice one mate..! just check with simon chity at kawasaki customer services, they do a stem valve seperately and I even have the part number which is 161260040 :smiley: of course I did ask this question when I phoned my local dealer, who said it was a complete unit. they also said they have order the full sensor now. I quickly pointed out, I asked if this stem was supplied seperately and you said know. so why I'm I paying for the full sensor when I don't need to..! he said he will check it out and get back to me. p.s thanks for this information :clap: another p.s..lol.. don't suppoe you know or can find out a.s.a.p what the car valve stem came from, could try and pick one up!
you know what, im gonna go and see my tyre guy and find out what car valve he used as a fix, maybe order a bunch of them and then we all can have a spare . It was a valve i think from a renault , its held in by a nut just under the inflatey part , but its a great spare to take in your tool kit whilst touring. just got back from Italy and i was shittin' it that id have a puncture and the mario brothers would end up doing the repair and crushing my TPS again
I can see how the TPS can get destroyed when the tyre is removed. Although the TPS is in fact quite small, any of the following done to break the bead
at the value will damage it:
- Positioning the bead breaker at the base of the tyre (almost guaranteed TPS damage)
- Positioning the bead breaker at a point higher than the TPS sensor, but then allowing the bread breaker to travel excessively. The rim of the tyre then breaks the TPS.
Bear in mind it can also break when:
- Using a lever to remove the tyre once the bead is broken. Just watch how they insert the lever. Sometime almost vertically down and if the TPS is in the way, then its adios TPS
- Getting the new tyre over the rim (unlikely though)
On a side note, I know many trust the dealer to do this and in most cases its fine. However, I very much doubt the dealer will do most of the following: grease the splines, axle and bearings. Check bearings for excessive play. Inspect and grease the dust cover. Clean the spacer with brake cleaner and inspect damage. Torque all nuts and bolts correctly. They'll give you a new cotter pin though, as it shiny, and gives the illusion its all ok.

this is one of the reasons why I removed the wheel myself, because I wanted to make sure the splines where greased with the correct moly 60 grease, and also wanted to clean and copper grease the pad pin while I had the caliper off, and make sure all is torqued correctly. the mistake I made, was to trust a "very experience" motorcylce tyre remover. by "all accounts" he's very good :whistling: but he has obviously become to complacent over the years. I won't be making that mistake again..
If I wasn't desperate to do my tyre change this week, I would have taken pics and done a guide.
However, if you can't be bothered with doing it yourself, there is one thing you can do when you go to the garage. Take some Moly 60 paste, grease + brush, brake cleaner and a rag. Once you've watched them safely take off your tyre, you can grease the spline with the Moly 60. Then squirt some brake cleaner onto the spacer and clean that. By this time they should just be finishing balancing the wheel. Put some grease on the brush and liberally apply to the dust seal and bearings.
You can tell if your bearings are on the way out when they balance the wheel. Just listen for a rumbling sound.
Edit: it's probably worth replacing the dust seal. Takes a few seconds
