I noticed that the 955i only had this eccentric adjustment for a few years before going to a standard slide/lock system.

Is there any benefit to the eccentric swing arm (other than being a cool deep-blue anodized color)?

On a whim, could you actually flip the eccentrics upside-down to lower the rear end?

I also can't figure out exactly how to use them... my owners manual says to loosen the left OR right adjuster clamp bolt. Do they mean AND?

Yes.

AND not OR

FWIW, my eccentric is upside down to lower the back. You will probably need to sod around spacing the chainguard rear mount to gain clearance.

Cons: I reckon my wheel alignment goes out every time I try to adjust the chain and of course the alignment marks don't align when you've swivelled the eccentric. I did punch new marks when I first got the bike, the dealer having swivelled for me. It struck me only yesterday when checking the alignment - were the wheels in line when I originally punched the new marks? Doh!

Ouch! Good point! Looking at either side I see no visible marks for adjustment. But, the chain is perfect as is, so I may just leave it be until the next oil change and fiddle with it then.

Thanks for the info! Depending on how road-riding works out I may drop the rear end as you have.

Chazzy,

Do you slacken off the spindle when you adjust the chain as this almost guarantees that the wheel will go out of line?

And mine was out of line when I bought it - after the dealer I got it from had changed the rear tyre......

It is easier to get out of alignment with them, but once you get the hang of it, tightening your chain takes about 60 seconds. I think the setup is great.
