So I ran it in for 2 hours at 6v and 30 mins at 9v and it does seem to have made the vibrations less violent although still more than other motors. 

I didn't know the blue/red!/green gunk was for balancing, this motor doesnt have any but a few of my 20k sharks do.

Even if I did open the can, how would I know where to add any ballast?
