Remember, the TPS is a datum and shouldn't be moved before checking the settings of No4 carb.
You need to check butterfly operation, throttle cable and linkage freedom/movement, air screw condition/setting, idle speed and that's pulling the correct level of Hg (230 - 250) at the correct idle. If it's not there's a problem that you need to sort out on the carb.
No 4 carb is non adjustable when carrying out balancing it's the datum. The biggest mistake and what leads to many TPS failures is owners and stealers adjusting them before checking the settings above. In theory unless strip/take the carbs the TPS should rarely if ever need adjusting, that's why from the factory the screws are covered in paint.
My own Fazer 99, still has it's OE TPS, all those I work on for owners still have theirs. All of the TPS's I've had to adjust over the years are because one of the above mentioned have moved it, due to incorrect balancing, sticking throttles and/or people messing about with them.
I've only replaced 3 OE TPS's due to failure and these where 80k plus mileage, obviously this is likely to increase as bikes age, some Fazer are knocking on 27yrs old now.
