you might want to change the brushes and the springs on that motor , I got one and it was a slow not so much rpms,after rezapping the magnets ,cut the comm(was not round at all) installed a pair of F brushes with purple springs + & - the RPMs came up from 23347 to 29142 and the total watts from 103 to 129 watts(@7 volts)
