Faulty thermostat?
Discussion
My 450 only shows about 70 (or a bit less) on the temp guage during normal driving but if I leave it ticking over the fans kick in at about 87 degrees. Reading some other threads it sounds like this may just be the guage under reading slightly but I am concerned that the normal running temp is too low - does this sound like a faulty/incorrect thermostat, as I'm tempted to try changing it?
It sounds about right to me and the same as mine.
There are many threads re running temp but there is a concensus with good reasons to run the engine as cool as possible. Something to do with liners etc. The engine needs to be at operating temp to get right mixture etc so unless you are drinking fuel it sounds OK.
The gauge is only a guide.
If it were running too cool then the mixture would be rich so the plugs would be black. It might be worth checking a couple for peace of mind.
There is a thread that explains the theory of running cooler
Hope this helps

As higlighted you don't want to overcool the engine.
Keeping running temp around 80 degree is perfectly good enough to maintain stability of internals etc . .
Yours sound like it's about right. It also sounds like you have an 82 degree stat rather than a 74 which is preferred by many - myself included for summer running- moving back to an 82 for colder weather/winter running.

TRy this link as it has some info on recommended temps etc
