Don't know how much adjustment as:
a) Made a boo boo and mixed up rear and front band adjustment and had to redo it (it was obvious when I tried to back up and nothing happened).
b) In any event, by the time you loosen the lock nut, torque up and back off 1 or 4 turns, tighten locknut as required as required and smear master pipe sealant everywhere it's a bit hard to work out if its changed much.
However, it was previously jolting into gear when I stopped and this no longer happens and the changes are smoother so I suspect it was well out.
