Since no one else has asked yet; I will....

What does this mean? ">> Spec motors are to be unmodified from the factory"

Isn't changing connectors a modification? Stock connectors on many over the counter motors will not survive heat racing. What about replacing worn out bearings? Wouldn't that be considered maintenance? I thought this is why we when to a physical size limitations, because it's techable. It's already been determined that high end, high quality, and high dollar motors don't offer an advantage. Right?

I personally purchased a motor and the manufacturer claimed was 61.5mm in length; it showed up longer (62.94mm). However, I was able to take a little aluminum off of each end bell to put it in spec. Is this motor modified?

I am ready for the verbal beating!
