i used to have it set as tight as i could, but it may have finially gave some. i used a, i mean several stone bits and a dremel. just like you're thinking, i clamped the motor down all hooked up, then ran it while i ground away at it. it took a while, but it wasn't really that bad, just noisy. im thinking about getting another kb and doing the same for my 1/8 yusa rally project.
