You seem to have made a very common mistake and this could be your problem.
When balancing the carbs the amount of Hg pulled by each carb is very important they must all pull 230 - 250mm Hg at 1150 - 1250 rpm. This Hg reading sets the amount clearance on the butterfly which in turn gives you an idle speed and datum. Before you start you MUST ensure the pilot screws are set correctly and that the rest of the engine is within spec i.e. air filter, plugs valve clearance etc. When setting the Hg you my well have to increase or decrease the idle speed to keep it within the range, keeping them within the Hg range at the correct idle speed the whole thing is a balancing act hence the term "balancing".
If yours are outside this range even just one of them you will get poor low speed running at small throttle openings the TPS will be useless, on a correctly set up bike you can disconnect the TPS and you wont notice any real difference to be honest. Most bikes are not set correctly most stealers have no idea and use cheap untrained labour the same applies to DIY owners both taking little or no notice of Hg readings, most bikes I've worked on are all over the place.
If after doing all the above you still can't set the TPS then it's possible its shot but that is easily checked by doing a resistance check.
