yea, just trying to "shake the tree" - :twisted: - thought I might get some mileage outta that one - you caught me. I deal with it with my truck all the time... if I take the "scooter" to work for a week, it's like the truck has 4 flats!
Flat spotting is true. Go to a dealership and ask to test drive the vehicle that has sit stationary for the longest. It'll feel like it's about to vibrate apart for the first 10ish miles.
