I have several big old Sago Palms out in my yard. I have tried to remove the pups in the past but don't anymore. Its hard to do without causing damage to the pup and the tree trunk.
I have read its just a matter of twisting or snapping them off the mother trunk. If you can manage that, go for it. I can never find a little neck to snap or twist so end up cutting and destroying the pup.
