I picked up the scoot (used) with about 1,400 miles this June and have about 4,500 miles so far. Every so often I seem to picking insulation out of the vents.... it seems to be an issue for a few days.. then doesn't happen until a week or so later.
There was also a notch cut in the left grip so I don't know if the insulation is part of the previous owners handy work.... however, neither of the two dealers I frequent can answer if this is normal...
