Need 2-25 tooth 32 pitch, 6mm bore pinion

[lincpimp]

The front endbell screws on. I took one of mine off and drilled/tapped the std 25mm motor pattern on it. Not very difficult, you just need an 1/8 drill bit and a m3 tap. Put the holes 12.5mm from the center of the shaft, or 9.5mm from the side of the shaft.

The kb 45 motors are great. I have 4 of them and they make plenty of power and run cool too.
