Had to do some work on the old girl, and had the battery disconnected for about 2 weeks. I understand the procedure for resetting the TPS and what it does. My question is this. With this procedure, will my gas milage change? I am currently getting about 45 MPG. I am estimating the battery was last disconnected approx. 10,000 miles ago.

It depends on what work you performed. A difference would be noted from an adaptive reset not a TPS learn. I still don't think it does a TPS learn, yes I know I'm the only one who thinks this. Even if it was a self learn it would do it as you rode the bike.

There would be no reason for a manual TPS adjustment if it was self learning (with the exception of a base setting to keep it in range) but then again you surely won't hurt it with the key on and turning the grip lock to lock two times.

Well I had to make a call to a "source" and it was explained to me that the Motronic 2.4 does in fact learn the TPS limits. It does have a base setting that would need to be set with the idle control disabled then a throttle sweep to learn the end points.
It will learn on the fly as you ride but until or unless you use full throttle it won't know the max end point.
So that ends that for me.

It will also do an adaptive reset to the base settings with a battery disconnect. If nothing else was done such as a tune-up it can run a little rough until the adaptives reset to compensate. After a tune-up, air filter, fuel filter, plugs it would be beneficial to disconnect the battery to reset the adaptives.
