The three most hated letters T P S !!!!

It improves throttle response as it modifies the timing to suit the throttle opening, also stops pinging (poor combustion) when opening the throttle quickly. Depending on how it fails internally it can cause surging and /or extra vibration.

Hi ,not noticed any changes in performance but I don't ride everyday ,still waiting for a cooler day to have a test ride

When mine failed on the 600 the only thing I noticed that the throttle response was a bit off, but I thought it was down to poor fuel as It did not throw up any code. 
It made no difference to the power, but the throttle did not feel right .
When I checked during a service it would not change from 10000 on the clock which ever way it was turned. 
The new one bought, brought back the throttle feel again, but then I was riding every day which was probably why I noticed the change.

When it failed on the 1000 it was making my fingeres number in traffic especially around 3 to 4000 rev  and was surging on an off the throttle, but fine up over 5000revs no difference to the power, again not code on the Tacho
The new one has it back to normal. The new Suzuki one was €97 and the Yamaha on was €330. Exactly the same fittings and resistance measurements, but it need two pins to be swapped around as it works on the left side of the carb whereas the Yamaha one is on the right side. The work in different directions

Hi Unfazed,had a quick look at my tps yesterday, there's no reading from any of the 3 pins using a multimeter no matter what combination I try so I'd say it's died, when you say you had to swap two pins over on the suzuki tps which two?I noticed that the new tps (not mikuni) that I recently bought that didnt work(had a standing reading of 5.9 between the middle and either end pin but didnt alter when you turned the center )was also anti clockwise instead of clockwise.

That sounds like there is no connection internally, where did you get it? 
There are a few very cheap chineses made look alikes, but they either do not work or fail sooner than the proper ones due to poor or no quality control
It is usually from the lack of quality control.

It was the 1000 Fazer one that I changed, to get it to work on the right side,  unfortunately the 600 one is spring loaded and cannot be changed, you have to buy the one for the right side of the carburettors/throttle bodies.
For example the fuel injected XJR1300 has exactly the same TPS as the 600 Fazer but it is spring loaded in the opposite direction as it fits on the right hand side of the throttle body
