The top mounts on mine are simply pins coming off the frame. Are you maybe meaning the bushes in the swing arm for the bottom mount?
As Brando said, they'll have to out for the baking, but I'm not sure that you won't damage the finish when re-installing.
A cheap puller is 2 sockets, a long bolt with a nut & a couple of washers. Put the big socket on one side, the other has to be very close to the OD of the bush. Put the bolt through both & tighten the nut to push the bush into the larger socket.
