Especially the cap.

Only if the “high” mark on the expansion tank is above the highest point of the cooling system. On an XT it is not. The coolant can only be expelled into or drawn through from the expansion tank by a vacuum and only if the coolant level in the radiator is at or above the overflow pipe/valve which the cap controls. If there is any air in the pressurised part of the cooling system then that air will compress like a spring allowing the coolant to expand without creating any fluid pressure in the system and nothing will enter or leave the expansion tank (the air pocket will do its job instead).

Any suggest a reliable meter monitor to watch the temperatures of critical systems, some thing that isn't took expensive

If you are sure the rad cap is good and the levels are all correct then it might be worth checking the temperature sensor. This can be done by plugging the bike into a diagnostic tool or removing it and checking its resistance suspended in a pan of water gently raised in temperature up to 100C and cross referenced against a thermometer.
An alternative would be to fit a temperature gauge which would also tell you what’s going on.
I fitted a KOSO temperature gauge to monitor what’s going on as I have a general mistrust of warning lights as they often only ever tell you anything useful when it’s too late.
It fits in the top hose like this:
