You need to check the TPS before doing a carb balance anyway, only takes a minute to see if it's in the right position or possibly faulty.
I've had 2 of those break down on me before, and the bike tends to feel as if it's just not happy with itself, especially at lower revs where it can feel a bit jerky.
Difficult to explain really, but i can sense now even when it's not positioned correctly, although the readings can also be false as well just to make things even more tricky, as both of mine started to break down rather than simply stop working, which would've given me a blatant reading of 3000rpm.
