Sticking thermostat?

[Bill in OKC]

Has anyone had a problem with their thermostat sticking?  My bike is 8 years old now and I've started noticing the engine temp fluctuating a bit differently than the first 7 years.  Like the thermostat moves in jumps instead of smoothly.  The part is priced in Ducati bucks

I've not seen any thermostat bad behavior.
Not a blanket endorsement, but I've not even heard of an issue.

You can drain the coolant and remove the thermostat and check it.

Thanks for the input.  I've replaced both sensors and no difference.  I will remove the thermostat and see how it works in water as it heats up.
