Aprilia RS 125 overheating

Request from someone how to test thermostat on RS 125 .

I did a little video on it nothing amazing but might help .

Id check radiator fins and then antifreeze water solution and then make sure the system is bleed properly as an airlock can stop flow this has usually been my problem locked air needing bleeding out 

you can check a rad and flow by testing inlet and outlet temps as well .

If these are ok id then check thermostat by testing to see if it opens , see above video .

Then if all this is ok its time to go in engine and check water pump and reverse flush the entire system and maybe cylinder head gasket replacement.
