What owners report

Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.

In hot humid conditions the scooter stalled-out or would not start. Initially, I thought it might be related to the summer blend of fuel, but then it occurred to me that it had run fine in the same conditions the previous five summers.
