'03 450 EXC overheating

[40YrLocust]

I've reciently cleaned the carborator on my 450 and had some work done at a local shop. Since then the bike is running very hot. Yesterday after cleaning the carb I started the bike and while ideling it overheated and coolant was leaking from the radiator. I'm not much of a gere head so other than flushing the coolant...what can I check?

ok, i should have just googled the issue to begin with. Evidently there are overheating issues with KTMs and it is recomended not to let them idle for too long. Also, there were some recomendations about jetting so I will go in that direction.
