Whatever they’re called, for this discussion the rollers are the center piece between the side plates. Can you see the shiny part at its edge? They appear on almost all of the rollers and disappears when they come onto the sprocket as they move around. At the end of my last tour and ever since when the chain warms up I hear a chunking kind of sound as though the chain is wonky. If I pull the clutch in the sound goes away but the sprockets are still turning? Taking off from a stand still the chunking sound is very prevalent and I’m guessing it continues as I ride but with wind noise around my helmet I can’t hear it. Accel or decel is the same as long as the clutch is engaged. On my tour the chain picked up a piece of wire that got ground up and I thought a piece of it may have got caught on the front sprocket but it was clean. New chain or do all chains do this? I also found a piece of rubber just sitting free in this slot. It has a groove in it as if it’s supposed to go somewhere other than this slot it fell? into. Any ideas?
All the chain links flex easy enough, maybe too easy?, no stuck or sticky ones. I’m thinking maybe those ‘rollers’ aren’t supposed to move around like that within their (slots) just when they come onto the sprocket teeth? But I’ve never looked at them this way. Almost all of them move like the pics show, the shiny area that appears when they come onto the sprocket, but not each link. Could nearly every roller be busted?
Could the combination of nearly every link flexing like this under a load be causing the chunking sound I’m hearing? And why the sound goes away when I pull the clutch lever in so there‘s no load on the chain but it’s still spinning?
