i just got my 750 f01 changed to the 90c tstat.
im in tampa, florida.
before my operating temp was 105c to 108c. now with the 90c tstat, the temp is normally around 98-102c. goes down to 93c under "sport mode" and crusing on the freeway.
my first concern is that my oil temp is around 99c most of the time. i like the oil to be a bit hotter to burn off any moisture in the oil or the engine.
i ordered the tstat on the link above and had an indepedant shop put it in. about 500 USD altogether.
