MrMax, the thermostat from Wattman is a bit larger than what is installed in your RX3.

OOEM on the left (with the rubber gasket removed) and Wattman 90C model on the right.

Inside the thermostat housing there is a ledge that you will need to remove in order to fit the new 'stat. Here's the stock housing:

I milled that ledge down, you can use a grinder. My end result:

you can see that you do not have to take off a lot of metal. Now my bike gets the oil up to about 100C on a decent ride. I have yet to take any measurements in cooler weather but I fully expect to see the bike running in the 4 bar range and thus burning off excess fuel/water in the oil.
