Overheating on run stand

I realize I'm late to this LOL

However this spawns the question who in the hell has a tight motor that runs hot because it's tight? LOL inconceivable.
That biotch would spin bearings if friction was literally created by short clearance.

In my experience only Motors that are new and running hot... is because the tune/timing isn't right yet...or they use an inadequate radiator/cooling system
