I've removed the shock, mainly because it sounded like that's where it was coming from. Bushing aren't new but also aren't the problem. I did some turning and twisting of the spring(Progressive 412's), seemed a bit loose but nothing to get concerned over. Put it back on and went for a ride with my hand down on the shock near the top. Sure enough, when I hit a bump I got a clank and felt it there. Wonder if it could be internal. Any thoughts? Or, could it be the spring slapping around inside that top cover. Thinking about stuffing a scrap of cloth up in there alongside the spring to see if that stops it. If it does, might be time for a rebuild or replacement.

When I get that noise, my exhaust is loose at the rear mount. |

Hmm, I guess it's possible to transmit a clank from the muffler mount up through the shock. I'll have to double check that mount, see if one or both nuts are loose.

Another possibility, though you wouldn't think so, is if your rear pads are a bit worn the brake caliper might be clanking  |

Well, it's not the muffler hanger nuts and the pads aren't worn very much. Just for kicks, I folded a piece of manilla folder and stuck it up between the spring and the ~ 2" cap that comes down over the top of the spring. There's a nice bump a block down the street that will tell if it's less noisy or still there.

Always good to have your own personal test bump – because I don't see any use for speed bumps otherwise  |

Has the pre-load been backed off to the point it will clunk?

Shouldn't be. When I installed them I set them midway with HD springs, haven't touched them since. |

In short....I never found anything. While I had the shocks off I switched them back to standard springs in place of the HD. Has a better ride now, not as harsh. Only thing I found was one of the rubber insulators was missing, goes under the forward exhaust cover and it was more of a rattle. Replaced that and made sure the cover was well clear of the exhaust to eliminate that possibility. Took it for a short spin around the block, still had a bit of a clunk but much subdued. When I spin the rear wheel there is no noise coming from the bearings, shouldn't be since I switched to the double row at the last service. I've decided to ride it and see if the sound gets worse, it just doesn't make enough of those noises to let you track it down.
One bad thing I discovered this evening while putting it all back together; the battery needs replacing. It's only about four years old, I usually will replace it every three years but didn't this time since I haven't been riding much. When it's idle I always have the battery tender hooked up. Alternator is putting out good so guess it's time for the battery.
