Think this is the same for the tolerances on bearingseats, roundness, concentricity, etc..
But do you think they measure this on a machine for handpicked motors, how could they otherwise know they have a good casing.
What is your opinion on building a new engine in a proven good used casing.
We drive stock motors and i have a motor with over 10km/h topspeed then average,
should i use the casing when i buy a new motor and put all the new stuff in there..?
