Even in Colorado, 82C would be nice.
First off, it's safe to assume you have a stock 89C thermostat. In order to see what thermostat you have, you have to do 95% of the work to remove it. For that effort, you might as well go out and buy a 82C thermostat and put it in. If you haven't replaced the thermostat in 2 or 3 years, it's time to replace it anyway.
Thermostat replacement is easy on a 900. Follow the top radiator hose back to the engine. It mounts to a metal pipe that's part of a dome-shaped casting held to the engine with two bolts. That's the thermostat housing. Use a turkey baster to pull fluid out of the coolant reservoir. With a cold engine, unbolt the housing. Yes, some coolant will run out. Not a lot. The thermostat will have the temperature stamped on it. Now, you could put the housing back on and bleed the system, or for the effort of plucking the old one out and putting the new one in, you've changed your thermostat. After putting the cover back on, refill the system and bleed it. You do this by running the engine and loosening slightly the bleed nipple right next to the thermostat housing. Stick a piece of hose on it with the other end in a jar. With the nipple just slightly open, wait until the fluid coming out has no air bubbles. That's it.
The thermoswitch may have a temperature stamped on it. It's mounted on the radiator.
Good luck!
