Which engine does your shadow have [600, 750 or 1100], and which model is it.
There are two small socket head bolts located on either seat of the seat below the seam that seperates the front and rear seat and that bolt the seat to a bracket on the fender. Remove the bolts then slide the seat straight back to remove the slotted bracket that holds the back of the passenger seat to the fender. A link below may help.
