Holy cow man, I've seen the broken in chunks and dried up, but not totally gone! Any way someone put it back together without it? Were there any remnants of it left in there? Honda sure is proud of those dampers though. Well at least you know what was causing it.

I wouldn't think they could disintegrate enough to be absolutely empty so I am sure they were left out. There wasn't even a hint of rubber in there. Odd that I haven't seen them around the shop or garage in the last year though.
If someone did put it together without them it was me. I've been the only one to work on the bike since new. I was able to find a set on eBay and ordered them already, hopefully they'll be here Saturday.

Guess overall it could have been worse, chain/sprocket or transmission issues would have cost a lot more than the $15 for rubber bits.

Hey, at least you have found the problem!
Should be a whole lot quieter when you next ride

Got the replacement cush drive yesterday (thanks to eBay it was only $14 shipped) and today's ride to work was so smooth and quite!!

I also ordered a replacement rear sprocket to try and bring down my RPMs at highway speed. Yeah, that didn't work out. My current setup must be 520 and I ordered a 525 sprocket. Guess I'll have to live with high RPM until I wear this chain & sprocket out.

Thats great news.
The 520 / 525 reference is applicable to the chain size, sprockets are normally referred to by the number of teeth, 45 / 46 being the norm for the rear sprocket.

Sprockets are also referred to by the 520/525/530 designation. Those numbers refer to how far apart the side plates are on the chain and how thick the material is that the sprocket teeth are. You can fit a 525 chain onto a 520 sprocket although there will be some extra slop side to side on the sprocket. However it is unlikely that a 520 chain would fit onto a 525 designed sprocket as it would be too thick for the chain to fit onto. The teeth would be the proper distance from each other, but the thickness of the sprocket itself would be too thick.

Yes, just hang onto that 525. Often 520 setups use alloy materials that don't last very long. If you're not racing and every ounce is critical, get steel sprockets. They'll last the longest.

Absolutely, it was only that there was no reference to the number teeth for the appropriate sprocket which of course it the main factor in determining the cruising speed.

His comment was accurate in referring to the new sprocket as being a 525, which his 520 chain would not fit (regardless of the number of teeth). Your comment about 520/525 being applicable to chains (exclusively) is inaccurate. The number of teeth is relevant to the gearing and RPM. But he was only indicating that it didn't fit.

Just being precise here

I never said or meant exclusively, you have clarified the position.
Thanks for that.
Cheers

The old sprocket is aluminum but since it is new I figure I have several thousand miles. No big deal, I'll live with it.

Current set up: 520 size with 15/48 sprockets.
Next set up: 525 size with 15/46 sprockets. Going to this to drop RPMs which are currently at 1000RPM for every 10MPH. Cruising to work I sit at a steady 7500 and it is just a little too buzzy for me.
