Monster 1100 EVO noise when hot

[HotIce]

OK, I would not call it really a noise , but it seems to me that when heat indicator moves to the fourth bar up, I ear a slight noise coming off the engine which I do not ear when the engine is colder.
Anyone else noticed it?
What is it? Change of oil viscosity due to heat, making the engine behave differently?
