Stephen,

Don't take the carbs off again!!

Find the disconnect/plug on the TPS wiring, get a good multimeter, make a semi permanent connection, if you don't have a friend, sit on the bike and work the throttle while imagining you are going around Donnington Park, Laguna Seca or wherever. No seriously open the throttle in increments. Whilst doing this check that the resistance, I think about 8-9k but you will see, changes smoothly and uniformly. record the readings doing this up and down the range. Slam the throttle open/closed see that there are no jerkingy readings.

Or if you have a timing light check the timing at idle. Mine was advanced rev the bike up see if it changes smoothly.

As you have a spare set of carbs you can check the "spare" off the bike to see what you get before doing the real one.
