Talked to my dealer's service mgr. on this issue, (he is also a big Honda dealer) and he stated that they see this wobble problem a lot with many makes and models, from Gold Wings to dirt bikes. On many of the gold Wings the factory was attaching a large heavy weight to the triclamps to dampen the vibs(my GL1100 had that). Anyway, he said the Honda owners were pretty fired up about spending that much cabbage and having a wobble, and that owners had spent thousands seeking a cure, often not found. He also said that the wobble, between 45-40 mph on decel, ususally disappeared above and below that speed, and that it usually got worse as the tire wore. Told me to bring mine in and they would check it, but I dunno. It'll either get better or it'll get worse, so for now I'll just ride.
