Ahh okay that makes a lot of sense actually…I can’t see any clear signs of the chain catching any metal on the frame or swing arm though.
Only thing i did notice is that the outside faces of the chain links look polished from what I think must be passing through the tensioner block.
The tensioner arm has a bit of side to side movement and is quite easy to push up down. Maybe both of these are contributing to a nasty noise?
@Glaynehaha yeah it’s bugging me too, chain & wheel seem to be nicely in line and spin freely with the bike in a stand.
