If the gap is too much, insert one more shim.....I have never use more then 2 shims ever on any V3 or MMM motors.
The motor already had 3 shims in it when I bought it, the shims were not something extra included. I took the motor apart to try and see if I can solder the wires directly on the bullet connectors (as they keep on coming out) and I accidently didn't notice which side the shims came off of. There was no long shim in my motor, only 3 little ones (1 of them is thicker than the other 2).
