Are you reading ° mechanically or electrically?
You said the bike was operated in a corrosive environment. Have you shaken the TB-shafts at idle? You can do so by wiggling the bell cranks. Have a fire extinguisher for this test: direct propane onto any of the induction path to look for leaks.
Have you checked the pivot bearings?

It's a readout of the motronic unit using the motoscan app (similar to a gs-911, but much cheaper and made to be used on a phone) so it's an electronic readout. Since I have no reference to the measured angles there is very little I can say about it.
The famous "blue paint" is very vaguely present on the tps mounting screws (maybe due to the slightly corrosive environment).The end stops or zero position I have not looked at yet.
Pivot bearings are smooth and without any play, if you mean the paralever bearings.
I have not checked the TB shafts. Initial throttle response is crisp and very good. I don't suspect anything mechanically wrong with the TB's.
First thing I will do is swap out some stick coils, a friend of mine has a R1150gs with good coils, I will ask him if I can borrow his for a test.
