Here are some basic pics. The tensioner doesn’t have much more room to move as it is fairly stretched as it is. I just want to make sure that I buy the right thing – even if a better tensioner is the way forward.
One thing I have noticed, is that the arm of the tensioner seems to “oscillate” slightly up and down when the chain is moving through it, almost like the tension is varying. It’s not by much but is noticeable, is this normal?
