Green92lx.....There was a test that was done over 50 years ago that proves me right. Do a search on google. Its called the the 60 hr test.
They ran 4 or 5 motors all at different temperatures, from 40 to 180 degrees to see how the temperature affects the motor. If you cant find it I might be able to scan the paper tommorrow.
