I bought the kit in 2016 for my 15 Multi (so this may only apply to DVT bikes). I didn't have a problem for quite a while but (I think) as the cush drives started to wear in and allowed the carrier to move more this issue became visible... it appears in my case the last week of hot weather riding did the trick because this wasn't presenting last week when I prepped for the ride.
Superlite part# - SCQ50A1200-15-42 - Superlite quickchange carrier purchased from Sprocket Center in 2016.
It looks like the carrier is improperly configured for my Multi and as the cush drives have worn and loosened up a bit it has allowed the carrier to contact the eccentric hub and damage both carrier and hub. I don't think this is necessarily a safety issue, but it DOES damage the eccentric hub.
The hub assembly has a washer that limits the ability of the carrier to move back into the eccentric, but this particular carrier design has an 11mm clearance on it's back that allows the carrier to float on the hub assembly... in this image you can see the clearance on the carrier as a gap between the carrier and the flange:
Over time the cush drives have loosened up and the carrier floated back into contact with the eccentric (because that 11mm clearance actually defeats the purpose of the washer by not limiting the motion of the carrier). Here's the contact damage on the eccentric:
I talked to Sprocket Center and they checked that this is the correct part for my Multi and have forwarded to Superlite. I'll keep you all posted but if you're running the carrier on your DVT Multi I strongly suggest you check for this issue. It's pretty easy to do... pull the carrier (you can do it without breaking the chain) and remove the cush drives then slide everything back onto the hub - this will allow you to move the carrier through all it's allowed motion without the cush drives locking things up. If things are right the carrier should NEVER come in contact with the eccentric hub, the washer should hold it away from metal to metal.
The only other thing I can think of is that the hub is somehow allowing the washer to move back more than it should... but I don't see how that's possible, the hub has a bushing that the washer rides against and it all appears to be correct - here's a vid to see if anyone else has any ideas:
