Hondaman has posted a LOT of info on the swingarm pivots and may offer a rebuild service.
My experience: the aftermarket bronze bushings do not fit. I gave up after returning 4 sets that were all too big: looser than the service limit. I installed the last set in the hope that they would shrink when pressed in the tight bore in the swingarm. Nope, and they sere not easy to get out again.
Also the collar that the bushings turn on wears. It becomes an oval shape. This part is long discontinued and unavailable.
Unless your swingarm is really sloppy I would leave it, otherwise talk to Hondaman and get it fixed properly.
If you remove the back wheel and get the shock top mounts off - and you can lift the bike a bit - the swingarm will swing down enough to get at the lower mounts. The upper mounts require that the shocks swing out a fair bit to disconnect and if they don't hit the pipes before releasing it puts unusual stress on the shock. I would not want to install new shocks this way since they are not designed for this bending stress and may be damaged.
