I picked up 2 used D ergs. One has 285km and the other 87. Both are in pristine condition and are 2008 builds. The one with more kilometres is quieter when the chain is pulled. Do they take a little while to break in and quiet down? I probely wouldn't of noticed it but after rowing on the higher kilometre one for a few weeks prior to purchasing the 87 kilometre one I noticed the difference right away.

Have you oiled both of the chains since you purchased them? Besides that, it could be that the less-used one has something on the chain that makes it louder as you row. Definitely start by oiling both then seeing if there's a difference - not that it really matters.

They tend to just get noisier with age. Just stripped down my Model C for the first time recently as you need to remove the chain to replace that gold coloured handle bush when it finally falls in half, usually near the end of a PB and proves quite a distraction.

I found that one of the chain pullys had no lubrication on the bearing and was a source of noise. Also cleaned the chain and boiled it in grease, the same stuff designed for motorcycle chains. The one way bearing in the flywheel should also have lubrication and the inside of the cover should be free from dust and fibre build-up. I understand the Model D & E are now quieter than the model C anyway due to the air intake design. Most of the noise is coming from the movement of the air and is therefore unavoidable.

I'm thinking it might be the area of the sprocket and axle where the noise is most noticable on the pull. The one with 85kil is the noisest by far. Would this eventually quiet down in time or should I see if I can get a new sprocket/axle combo while still in warranty?
