The one on my Fzs1000 failed recently at 68000km and it had not been touched either.
Adjusting them does not cause the failure, as you are only moving the start point of the TPS.
Yes they should be checked after the carburettors are synched and idle speed set.
They are mechanical and anything mechanical is prone to wear regardless.
I know of bikes with over 80000 miles and still have the original TPS, it is like most things mechanical some wear quicker than others.
All all Fazer carburettor are set to number 3 which is the reference/base carburettor as it has the throttle cables attached which is why you should really set 3 & 4 first then 1 & 2 and finally the screw between 1 & 2 to £ & 4is set.
Some came from the factory set incorrectly. Many 05 model FZS1000 had the Carbs and the TPS set incorrectly from the factory.
Wear and tear on the engine like Valves going out of adjustments effect the carb synch and when synchronised it can throw off the idles setting.
Adjusting the idle setting can throw off the TPs setting which is why it should be checked everytime you resynch the carbs
On my recent failure on the FZS1000 it tested perfectly on the tacho 0, 5000 and 10000 revs, but knowing I had a surging and vibration issue, I tested it with a meter and it was going open circuit around 2.7Kohm about half way through its rotation. No reason for it to fail at that point, but it did. I have a video of the test in MP$ format, but for some reason it will not allow me upload it.
I don't know why I bother sometimes, I really don't.
