Quite a few, you have to take apart most of the front.

Speaking of the VTS, how far do you tighten yours? I tried the stock setting (~1mm of threads showing) and it felt smoother and the belt actually didn't skip under hard braking anymore, but the outside pad was glazing over very fast (15 mins of driving and you could use it as a mirror). I went to 1.5 mm, and it glazes less, but still enough to be smooth after 3 runs or so.
I'm running a 550 size 5.5t LRP X12L at 14t.
