Unless he actually meant he moved or changed the TPS value.. He did say he moved it. Turned it a little each time. So that's what he did.So is this going to happen whenever I change my battery???
We are not sure what he did ... not 100% yet. BUT, to answer your question: NO, normally there is NO need to adjust TPS when a Battery is removed or unplugged for ANY period of time.
The only minor issues is that after about 10 minutes, Motronic-EFI looses internal memory of so-called "learned values" and this may cause minor running behavior compare to before battery was removed. Because of age, mileage, wear and parts tolerances, each engine is a bit different and Motronic-EFI may have learned larger fluctuation to base factory fuel map settings on yours. Hence, on some bike the changes in behavior, until "re-learned" may be more apparent - it may take a few start-stop cycles and a few rides.
The so-called "TPS reset" procedure that is often posted here in forums (ignition ON, twist / open throttle 3 times fully open, then fully close, ignition OFF) is really NOT absolutely required although many believe it is. This procedure was more critical in older Motronic_EFI 2.2 version (R1100 boxer engine 1994-2000) and this became and "old-truth" that has been carried around forums for many years.
CAVEAT 1: all above so called "learning" from Motronic-EFI assumes the Oxygen-sensor is functioning properly. In case where the O2 sensor does not work properly, then there is either: (1) no learning possible -OR- (2) very slow to adapt to out-of-tolerances settings of each engine.
CAVEAT 2: another very mis-understood factor in TPS learning is the importance of a good positive throttle close when handgrip is released (mechanical "click" at throttle-rail should be heard). When / IF the throttle-cables free-play is incorrect -OR- the throttle cables friction is such that the throttle rail does not close positively, you will have a problem anytime you unplug battery for more than 10 minutes. At next engine start Motronic_EFI will be very confused if throttle is not fully closed (at idle stop) the 1st time you turn ignition ON (it is re-learning at this point). Hence, the so-called "TPS reset" procedure may help as it forces you positively move throttle fully closed.
